• What type of mountain is formed at a subduction zone?

Row 1, Col 1

Volcanic Mountain

What type of mountain is formed at a subduction zone?

What is the mountain range called that runs along the bottom of the Atlantic Ocean?

2,1

Mid-Ocean or Mid-Atlantic Ridge

What is the mountain range called that runs along the bottom of the Atlantic Ocean?

• What type of mountain is formed when tension causes blocks of rock to move downward?

3,1

Fault Block Mountain

What type of mountain is formed when tension causes blocks of rock to move downward?

What type of mountain is formed when two tectonic plates collide?

4,1

Folded Mountains

What type of mountain is formed when two tectonic plates collide?

The tallest mountains are which type?

5,1

Folded Mountains

The tallest mountains are which type?

The boundary where two plates collide.

1,2

Convergent Boundary

The boundary where two plates collide.

• Boundary where plates move apart or away from each other.

2,2

Divergent Boundary

Boundary where plates move apart or away from each other.

A boundary where two plates move past each other.

3,2

Transform Boundary

A boundary where two plates move past each other.

Sea-floor spreading occurs at what type of boundary.

4,2

Divergent Boundary

Sea-floor spreading occurs at what type of boundary.

What is created at a boundary where sea-floor spreading occurs?

5,2

New Ocean Floor

What is created at a boundary where sea-floor spreading occurs?

A fault where the hanging wall moves down due to tension.

1,3

Normal Fault

A fault where the hanging wall moves down due to tension.

A fault where two fault blocks move past each other

2,3

Strike Slip Fault

A fault where two fault blocks move past each other

A fault where the hanging wall is forced upward due to compression.

3,3

Reverse Fault

A fault where the hanging wall is forced upward due to compression

Stress that is caused when rock is pulled apart

4,3

Tension

Stress that is caused when rock is pulled apart

Stress that is caused when rocks are pushed together

5,3

Compression

Stress that is caused when rocks are pushed together

• Theory that states that the continents have moved apart over millions of years, causing the same animal and plant fossils to be found on different continents

1,4

Theory of Continental Drift

Theory that states that the continents have moved apart over millions of years, causing the same animal and plant

fossils to be found on different continents

Theory that states that the Earth’s lithosphere (crust and mantle) move on top of the

asthenosphere

2,4

The Theory of Plate Tectonics

Theory that states that the Earth’s lithosphere (crust and mantle) move on top of the asthenosphere

Wegener’s name for the giant land mass that existed millions of years ago

3,4

Pangaea

Wegener’s name for the giant land mass that existed millions of years ago

When one tectonic plate moves below another plate, this is formed

4,4

Subduction zone

When one tectonic plate moves below another plate, this is formed

• This causes Earth’s tectonic plates to move

5,4

Convection currents

This causes Earth’s tectonic plates to move
