Plate Movements and Convection Currents

Question 1

Which plate is more heavy continental or oceanic?

Answer 1

Oceanic

Question 2

what is a Constructive plate margin?

Answer 2

At a constructive plate margin, the plates move apart from one another

Question 3

what is a Conservative plate margin?

Answer 3

At a conservative plate margin, the plates move past each other or are side by side moving at different speeds

Question 4

what is a Destructive plate margin?

Answer 4

A destructive plate margin usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement can cause earthquakes.

Question 5

Which plate margin causes a volcano to form?

Answer 5

Constructive plate margins. When this happens the magma from the mantle rises up to make (or construct) new land in the form of a shield volcano.

Question 6

What is subduction?

Answer 6

As the plates collide, the oceanic plate is forced beneath the continental plate. This happens because the oceanic plate is denser (heavier) than the continental plate.
