How can scientists determine if mountain ranges are the same age?

Determine if the mountains have the same age and type of rock.

Climate evidence for the theory of Continental Drift includes:

A tropical plant fossil was found in an island off the Arctic Ocean.

Fossil evidence included:

Mesosaurus, lystrosaurus and glossopteris

The theory that Earth's plates are in constant motion.

What causes Earth's plates to move?

Convection currents in the mantle.

The process shown at #8 is:

deposition, compaction, cementation

Alfred Wegener's theory of Continental Drift was rejected because

Alfred couldn't identify the forces that moved the continents.

The process of Seafloor spreading

Adds new rock to the ocean floor

Fossil evidence for Pangea included:

Glossopteris was on many continents.

Alfred Wegener had a lot of evidence that supported the theory that continents were once together. Evidence was from:

Land features, fossils, climate

7
Plate Tectonics is
Explains how subduction happens.
The theory that Earth's plates are in constant motion.
The theory that states Pangea once existed.
The theory that explains how new rock is added to the ocean floor.
8
What causes Earth's plates to move?
Convection currents in the mantle.
Convection currents in the outer core.
A volcano that erupts under Earth's crust.
Earth's crust floats on the ocean.

Far away from the mid-ocean ridge
12
When a sedimentary rock changes to metamorphic rock
Energy is added.
Energy doesn't change.
Energy is released.
13
When magma cools to form igneous rock
Energy stays the same
Energy is added
Energy is released
14
Alfred Wegener's theory of Continental Drift was rejected because
Alfred couldn't identify the forces that moved the continents.
Alfred's landform evidence was wrong.
Alfred's fossil evidence was wrong.
Alfred's Climate evidence was wrong.
15
Old crust gets pushed to trenches in the ocean. This process is called
Subduction.
Melting.
Weathering and Erosion
16
The process of Seafloor spreading
Creates rock that is flat.
Causes the ocean floor to shrink
Adds new rock to the ocean floor
Causes the magnetic field to reverse
17
Fossil evidence for Pangea included:
Similar mammals were on every continent.
Similar birds were on every continent.
Similar sea shells were on every continent.
