2. 1Water vapor is water in the form of invisible gas. Yes No Do you agree with the statement?

3. 2Water vapor becomes liquid during condensation. Yes No Do you agree with the statement?

4. 3The air temperature does not affect the steps in the water cycle. Yes No Do you agree with the statement?

5. 4When ice changes into water vapor it must melt first. Yes No Do you agree with the statement?

6. Water in the Air Water is always in the air as a gas called water vapor, which is invisible. There are also many gas particles in the air that are always moving, this movement against another object causes air pressure.

7. The Water Cycle Water is always moving on the Earth’s surface, underground and in the air as water vapor. The water cycle is the repeated moving of water through the environment in many forms. There are four steps to the water cycle: 1.Evaporation- changing liquid water to water vapor, when heated by sun. 2.Condensation- changing water vapor to liquid water droplets when temperatures cool forming clouds or morning dew. 3.Precipitation- water that falls from clouds as rain, snow, sleet (frozen raindrops) or hail. 4.Runoff- movement of water flowing downhill into rivers, lakes or oceans and takes the longest to happen. Frost occurs when water vapor freezes before becoming a liquid. Another path in the water cycle is sublimation which is when ice turns to water vapor without first melting. Third paragraph pg. 208

8. Many Paths of the Water Cycle Not all water stays in the water cycle because organisms make and use water for many things, like photosynthesis in plants. The distance from the ocean can affect the climate in an area. Energy from the sun keeps the water cycle going by causing most of the melting, evaporation and sublimation.
