Alfred Wegener

2

Which process in the earths mantle causes tectonic plates to move

Convectin currents

3

Where are volcanic eruptions and how does this relate to tectonic plates

On long belts that follow plate margins. Eg edge of the ocean .The destructive and constructive plate margins create volcanoes

4

where are earthquakes and how does it relate to plate tectonics

On plate margins. They are created from the build up and release of tension from the plates sliding past each other. It can also be made by oil extractions or underground mining.

5

whats an immediate response to an earthquake

search and rescue teams/ provide basic resources eg food

6

What landforms are created at constructive boundaries

shield volcanoes

7

What landform is created at collision zones

fold mountains

8

conservative
