Water Cycle
The process when liquid water is heated by energy from the sun, changing the water into vapor.
evaporation

Living things
75% of nitrogen on Earth is present as what form?
Gas
The _________ sphere consists of all the water on Earth.
Hydrosphere
Water in the water cycle that is in an underground reservoir (holding place) is called ___________.
Ground water
The process in which water vapor cools back into liquid water and begins to cling together (forming clouds).
Condensation
The process in which humans and animals take in oxygen and release carbon dioxide.
Breathing/Cellular Respiration

Nitrogen-fixing
The __________ sphere consists of all the rocks on and inside Earth.
Geosphere (Lithosphere)
Plants and animals are included in which of Earth's spheres?
Biosphere
The process in which water falls from the sky as a result of becoming too heavy for a cloud to hold (rain, sleet, snow, hail).

Atmosphere
Animals get the nitrogen they need by eating ___________.
plants or animals that have eaten plants
The process of water being pulled down by gravity back to the sources it came from (oceans, rovers, lakes, etc.)
Runoff
The process in which plants take in carbon dioxide to make sugars and release oxygen.
