Tectonics

Question 1

Draw and label the structure of the Earth

Answer 1

Question 2

What are tectonic plates?

Answer 2

Tectonic plates are ‘floating’ on semi-molten layer of rock in the magma. Convection currents within the mantle cause the plates to move.

Question 3

What are some examples of the different plates the Earth is split up into?

Answer 3

Pacific plate

Nazca plate

Indo-Australian plate

South American plate

Antarctic plate

Question 4

How do constructive plate boundaries work?

Draw a diagram:

Answer 4

Two tectonice plates are moving apart from each other. The gap in the crust causes magma to rise and cool. Earthquakes and volcanoes are found here.

Question 5

How do Destructive plate boundaries work?
Draw a diagram:

Answer 5

When two plates move towards each other, one sinks (is subducted) below the other once. Volcanoes and earthquakes are found here.

Question 6

How do conservative plates work?

Draw a diagram:

Answer 6

When two plates are moving side by side, in different directions or the same direction but at different speeds. earthquakes are found here.
