atmosphereC. Something that adds carbon to the Earth’s curstD. Something that removes carbon from the

Earth’s crust

Answer: B

ATMOSPHEREThe outer layer of gases

of a large body in space, such as a planet or star; the mixture of gases that surrounds the Earth; one of the

four parts of the Earth system.

BIOSPHEREThe living portions of the planet. This

is where all of the bugs, trees, and animals live.

CRYOSPHERE

The frozen regions of our planet.

COMBUSTIONThe act or process of burning.

CONDENSATION

The process by which a gas changes into a liquid

CARBON CYCLECarbon dioxide (CO2) and oxygen (O2) gases constantly circulate, or cycle, among plants,

animals, and the atmosphere

Multiple ChoiceWater that collects beneath the

surface of Earth is called

A. Lake WaterB. PrecipitationC. Ground WaterD. Springs

Answer: C

CYCLE

A series of events or

actions that repeat

themselves regularly.

NITROGEN CYCLEThe cycling of different forms of nitrogen (N)

among the atmosphere, soil, and living organisms.

True/FalsePlants and animals play a role in the

water and carbon cycles

True

Multiple Choice

Which of the following statements about water is true?

A. Water is necessary for life to surviveB. Water exists in liquid form onlyC. Water in ice is a gasD. Water covers ¼ of Earth’s surface

Answer: A

True/FalseAnimals get the carbon they need by

eating other organisms

True

PHOTOSYNTHESISThe process that plants use to create glucose

(energy). Water, sunlight, carbon dioxide (CO2), and chlorophyll are needed for this process to take place. This reaction takes

place in chloroplasts.

6H2O + 6CO2 ----------> C6H12O6+ 6O2

PRECIPITATION

All forms of water that fall to the ground or form on or near it, such as

rain, snow, dew, and fog.

POLLUTION

The introduction of harmful substances or products into an environment in

various forms.

True/FalseThe burning of fossil fuels produces

both air pollution and greenhouse gases.

True

RecycleTo put or pass through a cycle again.

True/FalseFossil fuels are a form of water formed

and stored inside Earth

False

Respiration

The process of water vapor being released into the atmosphere by animals.

Multiple Choice

How do animals add carbon dioxide to the atmosphere?

A. Through breathingB. Through evaporationC. Through cellular respirationD. Through transpiration

Answer: A

SmogA type of air pollution that occurs when

sunlight causes fuels, fumes and other gases to react chemically.

TranspirationThe process by which water

evaporates from the leaves of plants.

Water CycleThe continuous movement of water

through the environment of Earth

Decay

The natural chemical change that causes the slow destruction of something

EvaporationThe process by which liquid water

changes into water vapor.

Global WarmingAn increase in world temperatures

caused by increased amounts of carbon dioxide around the Earth

HydrosphereThe watery layer of the earth's surface; includes water vapor.

LithosphereThe solid part of the earth consisting of

the crust and outer mantle.
