Water Cycle

Point source pollution is...

• a form of  rain, hail, sleet, or snow
• an unknown source of pollution found in run-off
• moisture that is found on the outside plastic water bottles
• a known source of pollution like a factory where chemical run-off affects groundwater

What is it called when plants give off water vapor as a waste product?

• condensation
• evaporation
• sublimation
• transpiration

Any type of moisture that falls to the Earth.

• evaporation
• precipitation
• condensation
• transpiration

An area of land that drains into a body of water.

• mouth
• point-source pollution
• watershed
• headwaters

The supply of freshwater under the Earth's surface.

• watershed
• mouth
• headwaters
• groundwater

Waste that harms the land, water, or air is called

• reuse
• pollution
• recycle
• reuse

Which of the following would be considered point source pollution:

• A pipe leak
• Agricultural runoff
• Pesticides

The image is a model showing the processes of the water cycle. Water uptake to the atmosphere occurs through the processes of evaporation and transpiration from plants where it condenses to form clouds. Clouds release the water through precipitation. During a summer of extreme drought, what can we expect to happen to the surface ground water stored in ponds and lakes?

• water levels will increase because there is more precipitation
• animals won't drink as much to save water, so water levels remain the same
• water levels will increase because there is more evaporation and transpiration
• water levels will decrease because there is more evaporation and transpiration

A model of the water cycle was made using an aquarium with a glass cover, a container of ice cubes, water, and a lamp.
Which part of the water cycle causes the water droplets to form on the glass cover?

• condensation
• evaporation
• precipitation
• runoff

 Rivers, springs, and aquifers are all fresh water components of the hydrologic cycle/water cycle. As this water progresses through the cycle, it will eventually ___________ into the atmosphere before ____________ and falling back to the earth as precipitation.

• condense; evaporating
• evaporate; condensing
• dissolve; cloud-forming
• condense; precipitating
