Techtonic Plates

Question 1

What are different types of tech tonic plate boundaries?

Answer 1

• Divergent plate boundaries
• Convergent plate boundaries
• Transform plate boundaries

Question 2

Give a brief description of the action divergent plate boundaries preform.

Answer 2

Divergent plate boundaries are plates being pulled apart.

Question 3

Give a brief description of the action convergent plate boundaries preform.

Answer 3

Convergent plates boundaries are plates being forced together.

Question 4

Give a brief description of the action transform plate boundaries preform.

Answer 4

Transform plate boundaries are plates that slide laterally.

Question 5

What are the two types of plates?

Answer 5

• Oceanic plates

- Continental plates

Question 6

How does divergent plate boundaries separate oceanic plates?

Answer 6

The rising magma gently lifts the crust creating a ridge. The flow of convection currents pulls the plates apart and creates a fissure that is filled with cooling magma. As is gardens now sea floor is created.

Question 7

What is fissure?

Answer 7

A fissure means gap.

Question 8

What type of landforms will the divergent plate boundaries produce?

Answer 8

Landforms: Mid-oceanic ridge and sometimes volcanic islands (ex. Iceland).

Question 9

How do divergent plate boundaries separate continental plates?

Answer 9

The rising magma arches the crust upwards and spreaders it until it is thin and brittle. The central block sinks creating a Rift Valley. At first lakes form and eventually it may sink below sea level and become a new ocean basin.

Question 10

What type of landforms will the divergent plate boundaries create with continental plates?

Answer 10

Landforms: Rift Valley and graben topography.
