Advection The horizontal movement of an air mass (heat, cold, humidity) **Not a vocab word but should have been 

ATMOSPHERE The 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.

BIOSPHERE The living portions of the planet. This is where all of the bugs, trees, and animals live.

The frozen regions of our planet. CRYOSPHERE The frozen regions of our planet.

The act or process of burning. COMBUSTION The act or process of burning.

The process by which a gas changes into a liquid CONDENSATION The process by which a gas changes into a liquid

CARBON CYCLE Carbon dioxide (CO2) and oxygen (O2) gases constantly circulate, or cycle, among plants, animals, and the atmosphere

Multiple Choice Water that collects beneath the surface of Earth is called Lake Water Precipitation Ground Water Springs Answer: C

A series of events or actions that repeat themselves regularly. CYCLE A series of events or actions that repeat themselves regularly.

NITROGEN CYCLE The cycling of different forms of nitrogen (N) among the atmosphere, soil, and living organisms.

True/False Plants and animals play a role in the water and carbon cycles True

Multiple Choice Which of the following statements about water is true? Water is necessary for life to survive Water exists in liquid form only Water in ice is a gas Water covers ¼ of Earth’s surface Answer: A

True/False Animals get the carbon they need by eating other organisms True

PHOTOSYNTHESIS The 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/False The burning of fossil fuels produces both air pollution and greenhouse gases. True

To put or pass through a cycle again. Recycle To put or pass through a cycle again.

True/False Fossil 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? Through breathing Through evaporation Through cellular respiration Through transpiration Answer: A

Smog A type of air pollution that occurs when sunlight causes fuels, fumes and other gases to react chemically.

The process by which water evaporates from the leaves of plants. Transpiration The process by which water evaporates from the leaves of plants.

The continuous movement of water through the environment of Earth Water Cycle The continuous movement of water through the environment of Earth

Decay The natural chemical change that causes the slow destruction of something

The process by which liquid water changes into water vapor. Evaporation The process by which liquid water changes into water vapor.

Global Warming An increase in world temperatures caused by increased amounts of carbon dioxide around the Earth

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

The solid part of the earth consisting of the crust and outer mantle. Lithosphere The solid part of the earth consisting of the crust and outer mantle.
