Explain the physical processes that happen at conservative plate margins.

Using the diagrams below and the worksheet in your exercise book to answer the following questions:

CONSERVATIVE PLATE MARGINS

Are the plates moving towards each other, pulling apart or sliding past one another?

What currents move the plates?

What builds up here before an earthquake happens?

Why do volcanoes NOT happen at this plate margin?

Give a real life example of this plate margin (name the two plates or the area where this plate margin can be found).

Explain the physical processes that happen at constructive plate margins.Put these diagrams into the correct order:

1

Using the diagrams above and the worksheet in your exercise book to answer the following questions:

CONSTRUCTIVE PLATE MARGIN

Are the plates moving towards each other, pulling apart or sliding past one another?

What currents move the plates?

Why does an earthquake happen here?

How does the magma get out of the mantle?

What is formed when the magma cools and sets?

Give a real life example of this plate margin (name the two plates or the area where this plate margin can be found).

Explain the physical processes that happen at destructive plate margins.Put these diagrams into the correct order:

Using the diagrams below and the worksheet in your exercise book to answer the following questions:

DESTRUCTIVE PLATE MARGINS

Are the plates moving towards each other, pulling apart or sliding past one another?

What currents move the plates?

Why does an earthquake happen here?

What happens to the oceanic crust when it subducts (sinks) into the mantle?

What landform is formed at the subduction zone?

Why does increased pressure in the mantle lead to a volcano forming?

Why do fold mountains form at this plate margin?

3

Give a real life example of this plate margin (name the two plates or the area where this plate margin can be found).

Complete the table below using a tick or a cross.Plate margin Does an

earthquake happen here?

Does a volcano happen here?

Name the landforms found here (e.g. fold mountains, new crust ridges, ocean trenches)

CONSTRUCTIVE

DESTRUCTIVE

CONSERVATIVE

Using the map below, describe the location of young fold mountains and ocean trenches.

Which type of plate margin has ocean trenches and fold mountains?
