Read and answer the following questions.
What would it be like to live in the ocean? Many sea animals have found this to be the perfect place to live. Oceans cover more than 75% of the Earth’s surface. This means that the ocean is the largest habitat on Earth.
There are four oceans. They are the Pacific, Indian, Atlantic, and Arctic Oceans. The four oceans all connect to each other. There are also many seas. Seas are smaller branches of oceans. Some examples of seas are the Caribbean Sea and the Mediterranean Sea.
Have you wondered why the ocean is salty? Rivers collect salt as they travel over rocks. The salt filters out into the seas and oceans. It dissolves in the ocean but doesn’t evaporate. This means that the salt just builds up over time.
Waves on the surface of the ocean are caused by the wind. The stronger the wind, the stronger the waves will be. Waves only move up and down. Waves do not represent a flow of water.
