Mystery Science G5 L1: Hydrosphere & Water Distribution

Front

What is the hydrosphere?

Back

The hydrosphere is the part of Earth that is made up of water, including oceans, rivers, lakes, and ice.

Front

What percentage of Earth's water is salt water?

Back

About 97% of Earth's water is salt water, primarily found in oceans.

Front

What is fresh water?

Back

Fresh water is water that has low concentrations of dissolved salts, found in rivers, lakes, and glaciers.

Front

Where is most of the Earth's fresh water stored?

Back

Most of the Earth's fresh water is stored in glaciers and ice caps.

Front

What is the difference between salt water and fresh water?

Back

Salt water contains a high concentration of dissolved salts, while fresh water has a low concentration of salts.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually due to heat.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

Precipitation is any form of water that falls from the atmosphere to the Earth's surface, such as rain, snow, or sleet.
