Why is ocean water salty while rivers contain much less salt?
In this colorful 2D animated educational video, we explore the science behind ocean salinity and explain how dissolved minerals travel from rocks into rivers and eventually reach the sea.
Discover:
- How rainfall dissolves minerals from rocks and soil.
- Why rivers contain only small amounts of dissolved salt.
- How evaporation removes water but leaves dissolved salts behind.
- Why oceans have accumulated salt over geological time.
- How marine organisms use calcium to build shells.
This short science animation makes Earth science, the water cycle, and ocean chemistry easy to understand.
