Most of Earths fresh water is found in?

• Lakes
• Rivers
• Ice
• Groundwater

What is Transpiration?

• Water vapor rises into the atmosphere
• Plants draw in water from through their roots, then giving off water vapor
• Water moves from Earth's surface back to the atmoshere

As water vapor rises, it enters into a colder atmosphere, causing the water to condense into liquid water and clouds are formed

• Condensation
• Evaporation
• Transpiration
• Interception

As more and more water vapor condenses, the water droplets grow heavier and eventually will fall back to earth as rain, snow, hail or sleet

• Condensation
• Precipitation
• Evaporation
• runoff

What is the process of runoff?

• a small amount of Precipitation not evaporated returns to streams, rivers, lakes
• When a small amount of water turns into grounwater
• a combination of preicipitation and evaporation
• when water evaporates out of a plant

What is a watershed?

• Land that collects and channels water froma small body of water to a larger body of water
• the shape of the land determined by elevation
• A natural stream of water of considerable  volume
• a river and all its tributaries

Which of the following is a source of water for ponds and lakes?

• condensation
• eutrophication
• evaporation
• runoff

The land area that supplies water to a river system is called a

• water table
• trailer
• house
• watershed

What is Eutrophication?

• over long periods of time, nutrients can build up in a lake
• As lake organisms die, bacteria break down the bodies and release nutrients into the water 
• This process can change a lake - algae layers can become so thick that it blocks out sunlight and plants in the lake die 
• All of the Above

What is the term for an land above an aquifer.

• river system
• recharge zone
• aquifer
• watershed
