1. Distribution of Freshwater and Saltwater

2. How is Earth’s water distributed among saltwater and freshwater Earth is known as the “blue planet” because over 70% of Earth’s surface is covered with water. Earth is known as the “blue planet” because over 70% of Earth’s surface is covered with water. Most of Earth’s freshwater is found in the polar ice caps near the North and South Poles. Most of Earth’s freshwater is found in the polar ice caps near the North and South Poles. From largest to smallest, the amounts of water on Earth are salt water (97%), solid fresh water (2%), liquid fresh water (1%). From largest to smallest, the amounts of water on Earth are salt water (97%), solid fresh water (2%), liquid fresh water (1%).

4. Salt Water Most of the water on Earth is found in Earth’s oceans Most of the water on Earth is found in Earth’s oceans Oceans contain salt water. Oceans contain salt water. In order of size from largest to smallest, Earth’s oceans are the Pacific, Atlantic, and Indian Oceans. In order of size from largest to smallest, Earth’s oceans are the Pacific, Atlantic, and Indian Oceans.

5. Fresh Water Most of the Earth’s freshwater is located in the polar caps (ice). Most of the Earth’s freshwater is located in the polar caps (ice). Underground water, lakes, rivers, and glaciers hold the rest of Earth’s surface freshwater. Underground water, lakes, rivers, and glaciers hold the rest of Earth’s surface freshwater. The largest portion of the Earth’s liquid freshwater is trapped between underground layers of rock. This trapped freshwater is called groundwater. The largest portion of the Earth’s liquid freshwater is trapped between underground layers of rock. This trapped freshwater is called groundwater. A glacier is a very slow moving river of ice. A glacier is a very slow moving river of ice.
