Front 15

The process of Restoring land to a more natual productive state

Back 15

Land Recalmation

Front 16

The layer of rocks and soil above the water table in which the pores contain air as well as water

Back 16

Unsaturated

Front 17

A long period of low precipitation

Back 17

Drought

Front 18

A form of oxygen that has three oxygen atoms in each molecule instead of the usual two; toxic to organisms where it forms near the Earth's suface

Back 18

Ozone

Front 19

The situation that arises when more soil nutrients are used than the decomposers can supply

Back 19

Nutrient Depletion

Front 20

The area of permeable rock or soil in which the cracks and pores are totally filled with water

Back 20

Saturated

Front 21

Most or Earth's water is _______________.

Back 21

Salt Water

Front 22

What are ways to reduce motor vehicle emissions?

Back 22

Carpool or walk places

Front 23

How does acid rain form?

Back 23

cid rain forms when emissions from powerplants and factories burn coal and oil. The fuels produce nitrogen oxides and sulfur oxides when burned. The gases that are released react with water vapor to form nitric acid and sulfurc acid. The acids dissolve in precipitation and return to Earth's surface

Front 24

What are the effects of acid rain?

Back 24

Acid rain in a pond or lake can change conditions there. Many fish cannot survive there. Acid rain can damage plants bu affecting the nutrient level. Acid rain can also destroy whole forests.

Front 25

Compare and contrast ponds and lakes

Back 25

Ponds: Shallow water, Sunlight reaches bottom, Algae

Lakes: Deep water, Large fish, mollusks and worms

Both: Still water, Organisms live there

Front 26

A river and all the streams and smaller rivers that flow into it together make up a what?

Back 26

River System

Front 27

How can people obtain groundwater?

Back 27

People can obtain groundwater by drilling a well below the water table

Front 28

How can you reduce water pollution?

Back 28

You can reduce water pollution by effective cleanup of oil and gasoline spills, proper sewage treatment, and reduction of pollutants.

Front 29

Name examples of Agriculture wastes

Back 29

Animal wastes, fertilizers, and pesticides

Front 30

Why is agricultural wastes bad?

Back 30

When rain washes the wastes away it causes the algae to grow. The algae block light and deplete the oxygen in the pond.

Front 31

Name the sources of water pollution

Back 31

Human activities, wastes produced by agriculture, households, industry, and mining.

Front 32

Name examples of Industrial waste

Back 32

Chemical wastes and Metal wastes

Front 33

Name examples of Human Wastes

Back 33

Wastes that are washes down the sinks, showers, and toilets. (Sewage)

Front 34

Ponds

Back 34

Still and shallow water

Front 35

Lakes

Back 35

Front 37

Many uses of land, including logginh, mining, and farming expose the soil, which can lead to ________.

Back 37

Erosion

Front 38

Name a point source water pollution

Back 38

Oil spill from tanker
