00:00Oh my! This is a flood! Help! Help!

00:07But first, you need to learn about floods.

00:10Zoom in!

00:12Many of you might think that floods are a natural phenomenon.

00:17But it's not.

00:19Floods are a natural phenomenon.

00:22They are caused by the presence of water.

00:26Zoom in!

00:28Many of you might think that floods are just overflowing of water.

00:33Well, it is much more than that.

00:39An event when a dry piece of land suddenly gets submerged in water..

00:44..is usually known as floods.

00:47Oh! Don't take it lightly.

00:49A flood comes in all depths.

00:52Sometimes, it is so high that you don't even have a place to go.

00:58The power of floods is sometimes very dangerous.

01:02It can knock your car off and sweep you off your feet too.

01:08Causes of floods are heavy rains, river overflow, tsunami or hurricanes..

01:16..ice or snowmails, breaking of dams, etc.

01:21Oh! Help!

01:27So, a flood can be divided majorly into three categories.

01:34Slow-onset floods.

01:36This kind of flood usually happens when water bodies overflood their banks.

01:42As the name suggests, this one develops slowly..

01:46..which can last for days or even weeks.

01:51Rapid-onset floods.

01:53This kind of flood lasts for a day or two.

01:57Even though it is destructive, it still takes a little time to develop..

02:02..and thus giving people a chance to escape.

02:07Now comes the most dangerous of them all.

02:10Flash floods.

02:12This kind occurs within a very short time.

02:16That is, 2 to 6 hours.

02:19And sometimes within minutes.

02:21This doesn't give any time to prepare.

02:24No warnings, no words of caution, just destruction.

02:30But hey, don't lose heart.

02:33We can do our bits to prevent floods.

02:36Yes, that's right.

02:38Planting more trees help preventing floods.

02:43The roots of plants and trees dig deep into the soil..

02:47..and create spaces between soil particles..

02:50..which help in seeping and holding on to flood water.

02:55Trivia Time!

02:58Floods can even occur in deserts.

03:01In ancient Egypt, people relied on the Nile River floods..

03:05..because they created enriched soil for farmers.

03:10So, what are the three types of floods?

03:14Well, you keep thinking and post your answers in the comment section below.

03:20This is me Zooming out.

03:23Tune in next time for more fun facts.

03:27Hey friends, isn't the weather lovely?

03:30Wait a minute, is it me or is the ground moving?

03:35Whoa! Be careful, it's a landslide.

03:40Let me tell you about this natural disaster.

03:45Zoom in!

03:47When the upper mass of the soil gets dislocated from the lower layers..

03:52..and travels downslope, it is referred to as a landslide.

03:57It is also called a landslip or a mudslide.

04:02Landslides can be caused by a number of reasons.

04:06It could be either natural causes like volcanic eruptions..

04:10..soil erosion and sometimes heavy rainfall..

04:15..increases the wrath of landslides.

04:18Even human activities like mining, cutting trees..

04:22..increase the fertility of land and make it more prone to landslides.

04:28One of the most prevalent reasons is gravity.

04:33Well, whatever is up has to fall down due to gravity, isn't it?

04:40Landslides can either move very slowly like some millimeters per year..

04:46..or it could be disastrously fast, sometimes more than 100 miles per hour.

04:54But if you're living on a flat land with no hills or mountains, then you're safe.

05:01But if you're living somewhere between mountains and on a hilly terrain..

05:06..then my friends, you might be at risk.

05:09But don't worry, you could always prepare with some simple steps.

05:15Avoid building houses near steep slopes or at the edges of mountains.

05:21Stay away from drainage paths because water flow increases the speed of landslides.

05:28Landslides do not only happen on Earth.

05:32Many scientists believe that planets like Mercury, Mars and Venus have had landslides too.

05:40Woah! Looks like friends, I'm not even safe here.

05:45Trivia Time!

05:48Landslides can happen underwater too and they are called Submarine Landslides.

05:55The Hutt Mountain Landslide is the largest landslide ever recorded..

06:00..that has happened 50 million years ago.

06:05So friends, what are the other two names for landslides?

06:10Post it right below in the comment section and wait for more fun facts.

06:16This is me Zooming out!

06:21What's wrong with the water today?

06:24One day of no water can be so troublesome, isn't it?

06:28But can you imagine living for a week without adequate water supply?

06:33That's what happens in a drought.

06:35And this is what we'll be talking about today.

06:39Come on, Zoom in!

06:42Droughts are usually defined as extended periods of time with less than average rainfall.

06:49Causing a water shortage on the surface, in the atmosphere or in the ground water levels.

06:56It truly becomes a disaster when it begins to affect crops and the lives of people and animals alike.

07:05Droughts can lead to the destruction of crops, erosion of soil, severe shortage of water supply, etc.

07:15Droughts can be classified into four different types.

07:19These are Meteorological Drought.

07:22This kind of drought is specific to different regions based on the weather.

07:28For example, 20 inches of rainfall in a year is normal for place A.

07:35But the same amount could be very less to place B.

07:41Agricultural Drought.

07:43This accounts for the water needs of crops and agriculture.

07:48For instance, not enough water at planting may cause low yields.

07:54Leading to low plant populations.

07:58Hydrological Drought.

08:00Refers to continuous low water volumes in streams, rivers and reservoirs.

08:07Human activities can worsen hydrological droughts.

08:11Hydrological drought is often linked with meteorological droughts.

08:18Socioeconomic Drought.

08:20This occurs when the demand for water exceeds the supply.

08:25Examples of this could be when a state requires a lot more water than is produced..

08:32..from hydroelectric stations or underground wells.

08:37Now that you know about what droughts are, let me tell you some tips on how to survive them.

08:45The one major rule you must keep in mind is, SAVE WATER!

08:51So, here are some tips for saving water during a drought.

08:56Fill the washing machine and dishwasher to full before starting them.

09:03Wash fruits and vegetables in a bowl of water instead of under running water.

09:09Don't leave the water running while washing your face or brushing your teeth.

09:16Take smaller showers or if you use a bathtub, fill it only half way.

09:22And most importantly, RECYCLE!

09:26Don't waste water that can be reused somewhere else, such as to water plants or cleaning.

09:34TRIVIA TIME!

09:37Only 0.3% of water on earth is fresh water available for human consumption.

09:46A once thriving settlement by the Pueblo people in Chaco Canyon, New Mexico..

09:52..was abandoned in the 13th century due to a 60 year mega drought.

09:59Well friends, now you know what droughts are and how to prepare and survive through them.

10:06For more fun facts, tune in next time.

10:09Till then, this is me Zooming out!

10:13Woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

10:43Oh okay, well that reminds me that today's topic is Hurricane!

10:49Zoom in!

10:51Whoa!

10:53A hurricane is a huge storm that generally forms over warm ocean waters near the equator.

11:01The warm air above the ocean rises upward, thus creating an area of low pressure below.

11:08Air from the surrounding areas push in and try to fill the area with low air pressure,

11:15which now becomes warm and moist and rises too.

11:20As the moist air rises, the surrounding air again tries to fill in

11:26and this process continues till the water in the air forms clouds.

11:31Soon the clouds and winds spin around, fueled by the ocean's heat and water vapor.

11:39Therefore, hurricanes could also be called giant engines that use warm and moist air as their fuel.

11:48When we see from the top, hurricanes can be as huge as 300 miles wide.

11:55The center of the hurricane is called the eye of the hurricane, which is the calmest part.

12:03The eye wall surrounds the eye where the most damaging winds are found.

12:09It can range anywhere from 5 to 30 miles.

12:14Then comes the rain bands which surround the eye wall.

12:18These bands are a series of dense clouds that give a pinwheel like appearance to the hurricane,

12:25which range from 50 to 300 miles.

12:30Hurricanes are divided into 5 categories depending on the speed of their wind.

12:37Here, take a look.

12:40Category 3, 4 and 5 are the most dangerous ones.

12:45Trivia Time!

12:48A huge hurricane can release energy equivalent to 10 atomic bombs per second.

12:55Hurricanes in the Pacific Ocean are known as Typhoons.

13:01So this is me zooming out.

13:05Tune in next time for more fun facts.

13:09Bye!

13:15Whoa!

13:19You're laughing, right? Watching me tumble like that?

13:22Are you?

13:24Oh, no, no, go ahead.

13:29But hey, do you know what just happened?

13:33Whoa!

13:35There we go again.

13:38Well, this is nothing but an earthquake.

13:42A small one indeed.

13:43Come, let me tell you about earthquakes today.

13:48Zoom in!

13:50The surface of the earth is like a jigsaw puzzle.

13:54Yes, it's not a single piece of land, but approximately 20 pieces of a puzzle that constantly move.

14:02But you don't feel it because they move quite slowly.

14:07Each one of those puzzle pieces are called tectonic plates.

14:11So, whenever those plates hit, bump or slide past another plate, an earthquake is caused.

14:22The surface where these plates slip is called the Fault or the Fault Plane.

14:28So, when do you think it happens?

14:31Well, it happens all the time.

14:35But hey, don't be scared.

14:37Most of the times, we don't feel the quakes as they are too small to reach us.

14:44But sometimes, they are so strong that they can be felt over a thousand miles away.

14:52The place where the earthquake originates is called the Hypocenter.

14:57And the place where it occurs on the earth's surface is called the Epicenter.

15:03There are three types of earthquakes.

15:06Convergent Boundary

15:09Here, one plate is forced over another during an earthquake, which causes a thrust fault.

15:17Many hills and mountains have been formed due to the Convergent Boundary.

15:23Divergent Boundary

15:25Here, plates are drifted apart from each other, forming a rift zone.

15:31This kind gives birth to new ocean flows.

15:35Transform Fault

15:37Here, the plates slip by each other and this is also called Strike Slip.

15:44So, earthquakes are nothing but the shaking, rolling or a sudden shock of the earth's surface.

15:55Now you know that whenever the earth is stressed or angry, it shakes and grumbles.

16:02Haha! Don't be scared. I was just kidding.

16:07Trivia Time

16:09The instrument used by scientists to measure the intensity of earthquake is known as a seismograph.

16:17A tsunami is caused when earthquakes occur underwater.

16:22Bobo! Woah! Yikes!

16:26I need to rush before I tumble again.

16:29So this is me zooming out. Tune in next time for more fun facts.

16:37Hey! Hello friends!

16:44Oh no! I guess that's a tsunami!

16:49Come, let me tell you all about it.

16:53Zoom in!

16:55Tsunamis are caused by sudden movements of the ocean floor due to earthquakes.

17:01Landslides on the sea floor.

17:04Land slumping into the ocean.

17:08Large volcanic eruptions or a meteorite crash on the ocean floor.

17:14When an earthquake, a landslide or a volcanic eruption occurs on the sea or ocean bed..

17:24..a vertical joint is created which displaces the bed and causes extreme tension in water.

17:32The water is pushed upwards but gravity tries to pull it down.

17:38This causes an upsurge in the water levels and the waves start moving away from the point of tension.

17:47Tsunamis are barely felt as a ripple on the ocean surface as the water is quite deep.

17:55But as and when those waves reach the land, the water becomes shallower.

18:01And the waves constantly increase in height.

18:04They hit the shore and oh my! cause a lot of destruction.

18:11It is said the first wave of a tsunami is not the strongest.

18:17But the successive waves are bigger and stronger.

18:21Oh! And tsunamis can travel at a speed of about 500 miles per hour.

18:29Which is almost as fast as a jet plane.

18:33And that's why tsunami waves are called killer waves.

18:38Deadly, isn't it?

18:42Did you know that a tsunami wave can be less than 30 cm in height and can pass off unnoticed?

18:50If you get stuck in a tsunami, don't swim.

18:53Because the currents will pull you in the opposite direction.

18:57Just hold on to a floating object and be safe.

19:01So here's the deal, go watch this video to know more about earthquakes.

19:06After all, that's one of the major causes of a tsunami.

19:11This is me zooming out.

19:14Tune in next time for more fun facts.

19:22Oh! Hello friends.

19:24Oh!

19:29Are you wondering what this is?

19:32Well, it's the molten lava that comes out from a volcano.

19:38Come, let me tell you what a volcano is.

19:42Zoom in.

19:44I'm sure you've seen mountains that open up and blurt out thick molten semi-solid like substance.

19:52Well, that's called a volcano.

19:55Let's learn more about it.

19:59A volcano is a vent or chimney that connects magma from within the Earth's crust to the Earth's surface.

20:07The liquid rock is called magma when it is under the Earth's surface and lava after it comes out.

20:16So, how does a volcano erupt?

20:20The molten rock stored in the magma chamber rises through the crater pipe pockets.

20:26As it travels up the main vent, gases expand and water becomes steam, creating pressure.

20:34When the pressure can no longer be contained, the volcano erupts through the crater and secondary side vents.

20:41Common volcanic gases include water vapour, carbon dioxide, sulphur dioxide, hydrogen chloride, hydrogen fluoride and hydrogen sulphide.

20:54Popular belief is that volcanoes are large cone-shaped mountains, but that's not true.

21:01There are many more types of volcanoes, such as white plateaus, fissure vents, and volcanic eruptions.

21:09There are also volcanoes found on the ocean floor and even under ice caps, such as those found in Iceland.

21:19The word volcano originally comes from the name of the Roman god of fire, Vulcan.

21:28The tallest volcano in the solar system isn't on Earth at all.

21:34The tallest volcano in the solar system isn't on Earth at all.

21:39But on Mars!

21:42So, tune in next time for some more fun-filled facts.

21:46This is me Zooming Out!
