- One cubic foot of ocean water contains over 2 pounds of salt. The Red Sea and the Persian Gulf have the saltiest water.
- The oceans become salty because water picks up small amounts of dissolved salt minerals as it flows through rivers and streams. When this water enters the ocean, it slowly makes the ocean saltier.
- Winds cause the waves on the ocean’s surface. The tides are caused by the gravitational pull of the moon.
- The water spins clockwise in northern oceans; it spins counterclockwise in southern oceans.
- In the Atlantic Ocean is a huge mountain range. It is longer than the Rockies, Himalaya and Andes mountains combined.
