Water that is tired in layers of soil and rock beneath earths surface is called

Groundwater

1

The water and human wastes that are washed down sinks toilets and showers are known as

Sewage

2

Chemicals that kill crop destroying organisms are known as

Pesticides

3

Water that causes erosion picks up blank or particles of sand and rock

Sediments

4

About 97 percent of water on earth is

Salt water

5

Water that causes erosion picks up

Sediments

6

The water and human wastes that are washed down sink showers and toilets are called

Sewage

7

Chemicals that kill crop destroying organisms are called

Pesticides

8

Most water pollution of the result of

Human activities

9

Blank wastes agriculture wastes including animal wastes fertilizers and pesticides into ponds causing algae to grow

Rain washed

10

Wastes produced by agriculture households industry mining and other human activities can end up in

Water

11

Blank is stored in souk and rock beneath earths surface

Groindwater

12

Blank requires effective cleanup of oil and gasoline spill proper sewage treatment and reduction of pollinates

Keeping water clean

13

Most communities treat blank before returning it to the environment

Sewage

14

Where do wetlands form

They form in places where water is trapped in low areas or where groundwater seeps trough the surface

15

How are wetland important to migrating birds

They are home to many that are migrating during winter

16

Why do wetlands have a rich supply of nutrients

Dead leaves and other plants and animals materials serve as natural fertilizers

17

What are three common types of freshwater wetlands

Marshes
Swamps
Bogs

18

Describe two ways that wetlands are important to living things

Shelter
Supply nutrients

19

What impact has human development had on the Florida Everglades

Use for farm lands

20

Which of the following wetlands would have a large number of cats told and grasslike plants

Marsh

21

Which wetlands would have a great many tress and be in a humid climate

Swamp

22

Where would mangrove trees grow

Coastal wetlands

23

Which of te following is not an effect of human development on the Everglades

Poco sins

24

Some wetlands dry up during long hot summers and fill up during

Spring rain

25

Sometimes called the river of grads blank is a vast wetland

Florida Everglades

26

A poco sin is a type of

Big

27

A wetland that contains both fresh and salt water is called

Coastal wetland

28

Wetlands affect climate by making them more

Moderate

29

Two important roles of wetland are to control floods and act as

Natural water filters

30

Describe how convection transfers heat and materials in earths mantle

It causes material to rise and then sink to the mantel

31

What are the three types of boundaries between earths tectonic plants

Convergent
Divergent
Transform

32

What are convection currents in mantle responsible for reshooting earths surface

When plates seperate pass each other crash into each other

33

What causes earthquakes

Mantle convection

34

How are volcanoes formed

Subduction plates cause partial melting forming lawr the magma later rises forming volcanoes

35

How are ocean basins formed

When there are earthquakes and volcanic eruptions

36

What changes happen fast and which happe slow

Basin slow
Earthquakes fast

37

Earthquakes can form along blank boundaries

Transform

38

Convection currents in earths blank transfer heat and materials to the surface

Mantle

39

The crust is the blank layer of the earth

Coolest

40

Tectonic plates make up earths

Lithosphere

41

Convection currents blank move tectonic plates across earth

Slowly

42

Convection work because of a fluids blank changes as it's temperature rises and falls

Density

43

What might be found along a divergent boundary

Volcanoes

44

What explains how convection currents work

As a fluids temperature increases it's density decreases

45

Which of the following is not a cause of earths internal heat

Heat leftover from earths transformation

46

Which of the following is likely to from volcanic mountains

Molten material rises between two divergent plates
