Tectonics - What happens when tectonics plates move?

Question 1

What is subduction?

Answer 1

When an oceanic plate meets a continental plate and the denser oceanic plate slides under the less dense continental plate into the asthenosphere
This leads to the formation of a deep trench where the two plates meet.

Question 2

What is the ring of fire?

Answer 2

A string of volcanoes and earthquake sites that lie along the edge of the north pacific plate boundary

Question 3

How are fold mountains formed?

Answer 3

Where 2 continental plates meet and subduction cann0t occur. Instead the plates collide, causing the rock along the boundaries to to crumple and form mountains

Question 4

What are Convergent plate boundaries?

Answer 4

When 2 plates move towards each other and the thinner plate gets pushed under the thicker one. This process is called Subduction

Question 5

What are Divergent plate boundaries?

Answer 5

When 2 plates move apart due to convection currents. This type of movement mostly occurs under the oceans

Question 6

What are Conservative plate boundaries?

Answer 6

When the 2 plates slide past each other due to convection currents. Sometimes, the plates get stuck and build up pressure. This then casues earthquakes
