Read the passage. Then answer the question.

Liquid freshwater found on the surface of Earth's continents is called surface water. Rivers, lakes, and swamps are examples of surface water.

Earth also has a large amount of fresh groundwater. Groundwater is water that is underground. This water cannot be seen from the surface. So, groundwater is not shown on most maps.

This diagram shows a river on Earth's surface. It also shows layers below the surface. The brown layers show rock and soil. The blue layer shows groundwater.

Complete the sentence.

    Groundwater is _____________ water that is located _____________ the surface of Earth.

Read the passage. Then answer the question.

Most of Earth's surface is covered by salt water located in oceans. Ocean water contains between three percent and four percent salt. That is about as salty as one teaspoon of salt mixed into a six-ounce cup of water.

The water in rivers also contains a tiny amount of salt. Rivers eventually carry this salt into oceans. As ocean water evaporates, salts and minerals are left behind. Over time, the oceans become more and more salty. 


Select all of the true statements.
