Created by tectonic plates

Ex: mountains, glaciers

44
Q

Type 2

A

Erosion

Ex: valleys,hills

45
Q

Type 3

Q

What are the 8 different energy sources

A

Coal, petroleum, natural gas, nuclear, hydropower, geothermal, solar, and wind

47
Q

What 4 are non-renewable sources

A

Coal, petroleum, natural gas, and nuclear

48
Q

What 4 are renewable

A

Hydropower, geothermal, solar, and wind

49
Q

What is the different between renewable and non-renewable sources

A

Renewable resources produce energy by themselves and are captured while non-renewable sources are man made bc they need to be burned so we can use them, and they pollute the enviorment

50
Q

Fossil fuels

A

Dead animals and plants decompose

51
Q

Divergent

A

Plates move apart, new crust is created. Creates earthquakes and volcanoes. Creates rift valley

52
Q

Convergent

A

Plates move towards each other, crust destroyed bc one plate goes underneath each other

53
Q

What do convergent plates do

A

Create steep slope mountains, and earthquakes and volcanoes can result

54
Q

Transform

A

Plates move against eachother

55
Q

What do transformation plates create

A

Earthquakes and faults

56
Q

Hotspots

A

Vertical column of magma in middle of plate

57
Q

What do hotspots create

A

Because plates move over it then it creates volcano

58
Q

What does weathering do

A

Breaks rocks

59
