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

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

17. 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

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

19. 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.

The introduction of harmful substances or products into an environment in various forms.

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

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

24. True/False
Fossil fuels are a form of water formed and stored inside Earth False

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

26. Multiple Choice How do animals add carbon dioxide to the atmosphere?
Through breathing
Through evaporation
Through cellular respiration
Through transpiration
Answer: A

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

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

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

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

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

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

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

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