How has the amount of water on Earth changed throughout time?
• Answer: It is a closed system, which means the amount of water in the water cycle has changed very little over time.

3. How does the sun affect the water cycle?
• The sun affects the water cycle by heating up the waters in various places and causing evaporation.
• The sun is the source of almost all Energy on Earth.

5. Why are wetlands considered “pollution solutions”? How do they
help control flooding?
![Page 12: QPA Review for 3 rd 9 Weeks. Ch.10 Fresh Water 1. What percent of Earth’s water is salty? What percent is fresh?](https://reader031.vdocuments.us/reader031/viewer/2022020115/551b5c735503465c7e8b6044/html5/thumbnails/12.jpg)
5. Why are wetlands considered “pollution solutions”? How do they help control flooding?
• Answer:• They act as filters- As water moves slowly through a
wetland, some waste materials settle out, some wastes are absorbed by plants, and silt and mud are trapped by plant roots.
• Flood control: Wetlands help to lessen the impacts of flooding by absorbing water and reducing the speed at which flood waters flow during heavy rains. They also serve to store flood waters temporarily and release them slowly after the rain stops.

12. What is a deep current?• Answer: deep current: Deep below the ocean
surface, these currents causes chilly waters to creep slowly across the ocean floor.•These currents are caused by the differences in
density of ocean water.•Temperature causes water density differences.•At the poles, colder denser water sinks. At the
equator, warmer less dense water rises.

18.What causes high and low air pressure?
![Page 39: QPA Review for 3 rd 9 Weeks. Ch.10 Fresh Water 1. What percent of Earth’s water is salty? What percent is fresh?](https://reader031.vdocuments.us/reader031/viewer/2022020115/551b5c735503465c7e8b6044/html5/thumbnails/39.jpg)
18. What causes high and low air pressure?
• Answer:• caused by unequal heating across the Earth's
surface• LOWS- high winds, clouds, precipitation, and
tropical storms • HIGH- clear skies and calm weather.
![Page 40: QPA Review for 3 rd 9 Weeks. Ch.10 Fresh Water 1. What percent of Earth’s water is salty? What percent is fresh?](https://reader031.vdocuments.us/reader031/viewer/2022020115/551b5c735503465c7e8b6044/html5/thumbnails/40.jpg)
19.What causes wind?
![Page 41: QPA Review for 3 rd 9 Weeks. Ch.10 Fresh Water 1. What percent of Earth’s water is salty? What percent is fresh?](https://reader031.vdocuments.us/reader031/viewer/2022020115/551b5c735503465c7e8b6044/html5/thumbnails/41.jpg)
19. What causes wind?
• Answer:• The uneven heating of the earth’s surface -
warm air rises and cool air moves in (air moves from high pressure to lower pressure areas)
![Page 42: QPA Review for 3 rd 9 Weeks. Ch.10 Fresh Water 1. What percent of Earth’s water is salty? What percent is fresh?](https://reader031.vdocuments.us/reader031/viewer/2022020115/551b5c735503465c7e8b6044/html5/thumbnails/42.jpg)
20. Explain the conditions necessary to form a sea breeze and land breeze.
![Page 43: QPA Review for 3 rd 9 Weeks. Ch.10 Fresh Water 1. What percent of Earth’s water is salty? What percent is fresh?](https://reader031.vdocuments.us/reader031/viewer/2022020115/551b5c735503465c7e8b6044/html5/thumbnails/43.jpg)
20. How are sea breezes formed?
A sea breeze is created when the surface of the land is heated sufficiently to start air rising. As air rises, it is replaced by air from the sea; you have now created a sea breeze.
![Page 46: QPA Review for 3 rd 9 Weeks. Ch.10 Fresh Water 1. What percent of Earth’s water is salty? What percent is fresh?](https://reader031.vdocuments.us/reader031/viewer/2022020115/551b5c735503465c7e8b6044/html5/thumbnails/46.jpg)
20. How are land breezes formed?
A land breeze is created when the land is cooler than the water such as at night and the surface winds have to be very light. When this happens the air over the water slowly begins to rise, as the air begins to rise the air over the surface of the ocean has to be replaced, this is done by drawing the air from the land over the water, thus creating a sea breeze.

21. What is humidity?
• Answer:
• Amount of water vapor, or moisture, in the air.
• Humidity is determined by air temperature1. warmer air holds more water2. cooler air holds less water
![Page 52: QPA Review for 3 rd 9 Weeks. Ch.10 Fresh Water 1. What percent of Earth’s water is salty? What percent is fresh?](https://reader031.vdocuments.us/reader031/viewer/2022020115/551b5c735503465c7e8b6044/html5/thumbnails/52.jpg)
21. how do you measure humidity?• Answer:
• With a psychrometer• has two thermometers – dry/wet
bulb1. dry bulb – measure air
temp.2. wet bulb – covered with
damp cloth
• As air passes over damp cloth, water evaporates, energy transferred away, thermometer cools.

22. How does temperature affect humidity?
• as the temperature increases air can hold more moisture, so warm air is generally more humid than cold air.
• High air temperatures allow rainforests to become very humid

25. What does the term maritime tell you about an air mass? Continental? Polar? Tropical?
• Answer:
![Page 60: QPA Review for 3 rd 9 Weeks. Ch.10 Fresh Water 1. What percent of Earth’s water is salty? What percent is fresh?](https://reader031.vdocuments.us/reader031/viewer/2022020115/551b5c735503465c7e8b6044/html5/thumbnails/60.jpg)
Air Masses
Humidity
Temperture
maritime: forms over oceans. Water evaporates from the oceans, so the air can become very humid.
continental: forms over land and has less exposure to large amounts of moisture from bodies of water.
Tropical: Warm, forms in the tropics and has low air pressure.
Polar: : Cold, forms north of 50° north latitude and south of 50° south latitude and has air pressure.

27. What is a storm? Are you able to explain the difference between a thunderstorm, tornado, and hurricane?
• Answer:
• A hurricane forms over warm water produces long periods of heavy rains and very strong winds, and is water fed. (they lose their power once they leave the ocean. And usually covers huge areas.
• A tornado forms over land from thunderstorms. is wind fed and more localized
• Thunderstorm: a short lived storm that produces brief downpours, thunder and lightning and sometimes hail. Thunderstorms form in warm and humid air either on land or water.
