Earthquakes, Mountains, Volcanoes

and ValleysAll you need to know

Earthquakes are cause when two tectonic plates grind together.

Earthquakes

Earthquakes are cause when two tectonic plates grind together.

This can happen on converging and transverse plate boundaries.

Places where earthquakes are centred are called fault lines

Earthquakes

Volcanoes are caused by one tectonic plate slipping under the other.

Volcanoes

Volcanoes are caused by one tectonic plate slipping under the other.

This allows magma from the mantle below come to the earth’s surface.

Volcanoes

Volcano

Plate going below the other

Trench is created

Volcanoes are caused by one tectonic plate slipping under the other.

This allows magma from the mantle below come to the earth’s surface.

This is called subduction

Mountains are made by two plates coming together.

Mountains

Mountains are made by two plates coming together.

The rock has nowhere to go so it moves upwards making a mountain

Mountains

Rock Moves upwards

Mountains are made by two plates coming together.

The rock has nowhere to go so it moves upwards making a mountain

This is called mountain building

Mountains

Rock Moves upwards

Valleys and trenches are made by plates moving apart.

Valleys/ Trenches

Valleys and trenches are made by plates moving apart.

As the plate move apart the new rock from the mantle isn’t as high as the rock of the plate.

Valleys/ Trenches

Trench made by plates moving apart

Valleys and trenches are made by plates moving apart.

As the plate move apart the new rock from the mantle isn’t as high as the rock of the plate.

This can also cause mounds of new rock overtime higher than the plates.
