Groundwater Includes all the water underground.

1. What do you call the water in the aquifer and water table?

PERCOLATION

groundwater

Recharge happens when water percolates into the ground.

PRECIPITATION

2. How is groundwater recharge attained?

Water table

groundwater

Flood happens when the water table rises above the surface.

3. What happens when the water table rises above the surface of the earth?

Divide

A Divide is land that separates two bodies of water.

4. What is a divide?

Riparian buffers ( trees, shrubs, grasses on riverbanks) are important for good water quality.

Non-point source pollution is removed from runoff by plants before reaching the river or stream.

Erosion is prevented Erosion is prevented

5. Why are Riparians buffers important?

Riparian buffers are important for good water quality. Riparian zones help to prevent sediment and pollutants from reaching a stream. Riparian buffers include a native grass or herbaceous filter strip along with deep rooted trees and shrubs along the stream.

River

NO riparian buffer

Corn farm

Runoff with sediments and excess fertilizers.

Sediments and nitrates pollutes the river or stream.

Mississippi River Basin

There are many smaller watersheds within a river basin. Rivers and streams drains the watersheds.

6. What makes up a river basin?

precipitation Precipitation that falls flows downward usually creating a stream or river. The area of land that contributes water to a stream or river is called a watershed, or drainage basin.

watersheds.

Convection Warm air mass rises from the equator while cold air mass sinks from the poles.

7. What kind of heat transfer is responsible for the rising of warm air masses from the equator and sinking of cold air masses from the poles?

Convection Warm water rises while cold water sinks.

D. Wilmington

C. GoldsboroB. Fayetteville

A. Winston-Salem

8. A chemical factory accidentally released toxic chemicals at Cape Fear. What major city will be greatly affected?

D. Wilmington

•Less habitat for animals

•Less biodiversity

DEFORESTATION

9. How are we affected by deforestation and urbanization?

URBANIZATION•Less oxygen•More carbon dioxide

10. What benefits do we get from reforestation?

Runoff/flooding reduction

CO2 reduction in air. Less greenhouse effect, and acid rain.

Adds O2 in air. Better air quality.

Habitat for animals. Greater biodiversity.

11. How are the oceans affected by increasing temperatures or global warming?

Humidity increases means more or stronger precipitations.

More water evaporation from means salinity increases.

Sea Ice melts, adding more freshwater in the oceans causes seawater rise and flooding on low lying areas and coastlines.

12. How is water affected by temperature increase?

Warm water rises due to its lower density.

Convection

12. How is water affected by temperature increase?

Warm water loses its dissolved oxygen.

13. How do aquatic organisms benefit from upwelling in the ocean?

Wind causes waves and upwelling.

Upwelling ( rising ) water brings food near the ocean surface. Sea creatures feed.

14. Which layer of the atmosphere is the coldest and the hottest?

Troposphere

stratosphere

Mesosphere

ThermosphereColdest

-90 Celsius

Mesopause

90 Celsius

Hottest

15. What is the portion of land into which an area drains all of its streams and tributaries?

A. watershedB. tributariesC. riverbankD. groundwater

16. What benefit can a riparian buffer provide to the river in an agricultural area?A.prevent erosion of loose soil from

cropsB. reduce non-point source pollution

of surface water

17. What separates one watershed from another?A. divideB. aquiferC. mountainD. river basin

18. What is a negative consequence of deforestation?

A. making space to grow cropsB. reducing the effects of global warmingC. Less area for animal habitatsD. increasing biodiversity

reducing the effects of global warming is a GOOD consequence.

19. Which can hold more water vapor cold air or warm air?

Warm Air - Not as many air moleculesCold Air - More air molecules

Warm air: Less dense

Cold air: More dense

Warm air has more spaces between molecules that is why it is less dense and it rises.

Cold air has less spaces between molecules that is why it is more dense and it sinks and water vapor condenses..

Humidity increases. Water vapor condenses followed by precipitation.

Temperature: 53 F Temperature: 52 F Temperature: 51 F

20. The weather forecast is sunny skies with a temperature of 87 F and a dew point of 61. Why will it become more humid if the temperature were to drop?

A. water vapor would condenseB. water vapor would expand

21. What is an estuary?River flows downstream into the ocean.

River water ( freshwater) mixes with ocean water ( salty water)

Estuary

Rising tides can cause the estuary water to become more saline.

22.Why are estuaries important?•Nursery•Food chain•Biodiversity

23. Which uses the greatest amount of freshwater supply ?

Agriculture, 55%

24. What can be done to lessen or alleviate the freshwater requirements of farms ( agriculture)? Think!

Water crops at night. How can this help?

25. What is the composition of the atmosphere?

26. What is the most abundant gas in the atmosphere?

Match the characteristics of the layers of the atmosphere.

What's a River Basin? What's a Watershed?What is a River Basin?A river basin is the portion of land drained by a river and its tributaries. It encompasses all of the land surface dissected and drained by many streams and creeks that flow downhill into one another, and eventually into the Milwaukee River. The final destination is than an estuary which eventually carries it to Lake Michigan. As a bathtub catches all the water that falls within its sides, a river basin sends all the water falling on the surrounding land into the Milwaukee River, then to Lake Michigan and eventually the Atlantic Ocean.As an artery connects the parts of a body to one another, so a river threads together the creeks and streams, valleys and hills, lakes and underground springs that share a common assembly of water. Whatever happens to surface or groundwater in one part of the river basin will find its way to other parts. If water is diverted out of its downward course in one section, other parts will come to "know" of its absence. A river basin comes closer than any other defined area of land, with the exception of an isolated island, to meeting the definition of an ecosystem in which all things, living and non-living, are connected and interdependent.What is a Watershed?A watershed is simply the area of land that catches rain and snow and drains or seeps into a marsh, stream, river, lake or groundwater. What is the difference between a River Basin and a Watershed?Both river basins and watersheds are areas of land that drain to a particular water body, such as a lake, stream, river or estuary. In a river basin, all the water drains to a large river. The term watershed is used to describe a smaller area of land that drains to a smaller stream, lake or wetland. There are many smaller watersheds within a river basin.
