4. Concept map
Work in your group to create a concept map about water.

5. Concept map

6. Read the introduction and look for key ideas
Like clouds, fog is also
made up of tiny drops of
water. If you have ever
been in fog, you know what
the inside of a cloud is like!

20. Key vocabulary definitions
Cloud - A visible collection of water droplets in the atmosphere. Clouds usually form hundreds of meters above Earth’s surface but fog is a cloud formed near Earth’s surface. Condensation - The process of change in state from gas to liquid, or the droplets of liquid formed from this process.

21. Key vocabulary definitions
Evaporation - The process of change in state from a liquid to a gas. Freezing - To change from a liquid to a solid state. Humidity - The amount of water vapor in the air.

22. Key vocabulary definitions
Melting - To change from a solid to liquid state.

23. Key vocabulary definitions
Water cycle - The movement of water from one state to another as it circulates through the earth’s crust, oceans, and atmosphere. Water evaporates from the surface, rises and cools at higher elevations, condenses as rain or snow, and falls to the surface where it collects in lakes, oceans, soil, and rocks underground.

24. Key vocabulary definitions
Water vapor - Water in a gaseous state.
