1. The Water Cycle (Hydrologic cycle)
Unit 5 - Chapter 6
The Water Cycle (Hydrologic cycle)

2. Where is the Water?

3. Where is the Water?
Highest % of freshwater is used for agriculture
WHY?
More underdeveloped countries rely on farming
Why Water Is Important:
Single most EROSIVE agent on Earth

4. Water Cycle Objectives
Identify all important stages
Explain all important stages
Label all important stages
Draw all important stages

5. Water Cycle

6. Continuous process in which Earth uses and recycles its water source
Water Cycle
Continuous process in which Earth uses and recycles its water source
Powered by energy from Sun
Four (4) Major Components:
Evaporation
Condensation
Precipitation
Collection

7. 1. Evaporation - Water evaporates from oceans, lakes, rivers
Transpiration: Loss of water vapor from parts of plants and trees

8. 2. Condensation Condensation: Changing from gas  liquid
- As water vapor rises , it condenses into water droplets, forming clouds
Condensation: Changing from gas  liquid

9. 3. Precipitation
- When clouds have enough water in them and cannot hold any more
Precipitation: Water comes back to surface in form of rain, snow, sleet, hail

10. 4. Collection
Three (3) Options: 1. RUNOFF: Water flowing downslope along Earth’s surface as streams and rivers and eventually flow into lakes and oceans

11. 4. Collection
Three (3) Options:
2. INFILTRATION: Water that soaks into ground to become groundwater

12. 4. Collection
Three (3) Options:
3. GROUNDWATER: Water collected underneath surface that will return above as surface water

13. 4. Collection
REMAINDER: 4. Some evaporates back into atmosphere

14. Water Cycle Activity
Draw AND color a DETAILED water cycle by labeling ALL major components from below:
1) Evaporation
2) Transpiration
3) Condensation
4) Precipitation
5) Surface Runoff
6) Infiltration
7) Groundwater
On the back of your drawing, write a concise summary/description of EACH step above!
