Water Cycle Questions

1) What are the two sources of energy that drive the water cycle? (DOK1)

2) Explain how plants and animals contribute to the water cycle.(DOK2)

3) Explain how gravity affect the water cycle. (DOK2)4) Illustrate the water cycle. Includes these key words:

Evaporation, Condensation, Precipitation, Run Off, Transpiration, Infiltration, and Sublimation . (DOK3)

5) Explain what a water table is, and how its affected by the water cycle.

Project

• You must build a model of the water cycle that you can use to describe how it works to a blind person. The model must represent all the parts of the water cycle. You cannot buy new materials. It must come from materials you have at home.

Ecosystem Cycles:Water Cycle

The Water Cycle

1. Water cycles between the oceans, atmosphere and land. All living organisms require water.

A. Water enters the atmosphere as water vapor, a gas, when water evaporates from the ocean or other bodies of water.

Evaporation—the process by which water changes from a liquid to a gas.

B. Water can also enter the atmosphere by evaporating from the leaves of plants—Transpiration.

The Water Cycle

C. Precipitation--rain, snow, sleet, or haila. The sun heats the atmosphere.b. Warm, moist air rises and cools.c. Eventually, the water vapor

condenses into tiny droplets that form clouds.

d. When the droplets become large enough, the water return to Earth’s surface.

The Water Cycle

D. Run-off—Precipitation runs along the surface of the ground until it enters a river or a stream that carries the run-off back to an ocean or lake.

E. Seepage—Rain also seeps into the soil, some of it deeply enough to become ground water. Water in the soil enters plants through the roots, and the water cycle begins anew.
