The lesson
Look at a globe or a world map. You will see blue almost everywhere. That blue is the ocean. The ocean covers more of Earth than land.
Mia visited the beach with her mom. She tasted a little ocean water. It was salty, not sweet like juice. Her cup at home has fresh water.
Rivers and lakes have fresh water. The ocean's water is salty instead. That is why we do not drink ocean water.
The ocean is home to countless living things. Fish, whales, crabs, and coral all live there. More creatures live in the ocean than anywhere else on Earth.
The ocean is huge, salty, and full of life. It covers more of Earth than land does.
