Name 4 places where Earth's water is stored.

1 - d. The sun's energy heats the water. 2 - b. Heat causes some of the water to change from a liquid to a gas called water vapor. 3 - f. Water vapor rises into the air. 4 - a. Water vapor cools and begins to form water droplets. 5 - g. Tiny droplets of water begin to stick together and form clouds. 6 - c. Clouds get darker as more and more water droplets cling together. 7 - e. Water in the clouds becomes too heavy and rain begins to fall.

Place the following events in the order in which they happen: a. Water vapor cools and begins to form water droplets. b. Heat causes some of the water to change from a liquid to a gas called water vapor. c. Clouds get darker as more and more water droplets cling together. d. The sun's energy heats the water. e. Water in the clouds becomes too heavy and rain begins to fall. f. Water vapor rises into the air. g. Tiny droplets of water begin to stick together and form clouds.

Any form of water that falls from the sky back into rivers, streams, lakes, oceans, or back onto the land.

Precipitation

oceans and some rivers

Salt water is found in _____ and some _____.

97%

Salt water makes up approximately _____ % of the earth's water.

0 degrees C or 32 degrees F

Temperature at which water freezes

Evaporation

The process by which water is heated and changes ito water vapor.

Condensation

The process in which water vapor cools and forms droplets of water that cling together to form clouds.

Water Vapor

Water in gas form

Evaporation, Condensation, and Precipitation

What 3 processes make up the water cycle?

Fresh and Salt

What are the 2 types of water found on Earth?

Water vapor cools as it rises into the air. As the gas cools, it forms tiny droplets of water that begin to stick together and clouds are formed.

What is condensation?

The sun heats the surface of water, which causes some of the water to turn into its gas form, which is called water vapor.

What is evaporation?

The majority of Earth's fresh water is unusable because it is frozen in glaciers.

Why is the majority of Earth's water unusable?

Fresh Water

_____ _____ makes up approximately 3% of the earth's water

Salt Water

_____ _____ makes up approximately 97 % of the earth's water.
