Lichens are nitrogen fixing bacteria
3.

What is an example of an area that is likely to undergo primary succession?

a)

Glaciers melt and leave exposed rock

b)

Plants die from drought and decompose

c)

Land is bulldozed and soil remains

4.

Water vapor leaves a plant in the biosphere and goes into the atmosphere through

a)

transpiration

b)

respiration

c)

precipitation

d)

evaporation

5.

____ happens when liquid turns into a gas on Earth's surface

a)

evaporation

b)

condensation

c)

respiration

d)

transpiration

6.

reservoirs

a)

water storage areas during the water cycle

b)

places reserved for water usage by humans and animals

c)

made from water and ice that are too big to remain suspended in air

d)

made up of water droplets or ice crystals that are so small they remain suspended in the air

7.

Where is groundwater stored?

a)

in lakes and rivers

b)

in underground lakes

c)

in cracks and pores beneath Earth's surface

d)

in mid-ocean ridges

8.
After condensation, the droplets of water in the clouds fall to the earth in different forms
a)
precipitation 
b)
condensation
c)
evaporation 
d)
ground water
9.
Precipitation occurs because 
a)
the droplets evaporate in the air
b)
the droplets are too light for the air to hold
c)
the droplets are too heavy for the air to hold
10.
What is condensation?
a)
The part of the water cycle when the sun heats up water, turning it from a liquid into water vapor or steam. It rises from the ground into the air.
b)
The part of the water cycle when the water vapor in the air gets cold. The water turns back into a liquid and forms clouds.
c)
The part of the water cycle when clouds get heavy and can no longer hold the liquid water. This causes the water to fall from the sky to the earth as rain, snow, sleet, or hail.
11.

Plants exhaling water into atmosphere.

a)

Evaporation

b)

Transpiration

c)

Condensation

d)

Precipitation
