Types of Plate Margin

What hazard occurs at conservative plate margins?

Only earthquakes.

Where does a conservative margin occur?

Where 2 plates are moving past eachother.

What happens when 2 plates move past eachother?

The two plates get locked together in places and pressure builds up.

What happens when 2 plates get locked together?

Like destructive margins, this causes the plates to jerk past eachother (or crack, forming fault lines), releasing the energy as an earthquake.

Give an example of a conservative plate margin.

The Pacific Plate is moving past the North American plate.

Many earthquakes occur along here and its fault lines e.g. along the San Andreas fault in California.

Where does most volcanic activity occur?

At plate margins, but there are some areas of intense volcanic activity that aren’t near plate margins.

They’re caused by magma plumes.

What is a magma plume?

A vertical column of extra-hot magma that rises up from the mantle.

What forms above magma plumes?

Volcanoes.
