Plate Boundries

Question 1

Destructive Margin

Answer 1

Occurs when an oceanic and a continental plate converge (meet).

Question 2

Constructive margin

Answer 2

Occurs when an oceanic plate and continental plate move apart.

Question 3

Conservative Margin

Answer 3

Occurs when two plates move in the same direction.

Question 4

Collision

Answer 4

Occurs when two continental plates converge (meet)

Question 5

Name the two that cause earthquakes

Answer 5

Collision and Conservative Margin

Question 6

Explain Conservative Margin

Answer 6

As the plates move in the same direction they join and jam against one another. The Pacific plate moves quicker than the North American plate meaning that when the pressure is released there are earthquakes.

Question 7

Name the two that cause volcanic eruptions

Answer 7

Destructive Margin and constructive Margin

Question 8

Explain constructive Margin

Answer 8

The convention current pushes apart the two plates causing the earth to open up to then pressure to build and finally explode.

Question 9

Explain collision

Answer 9

Neither plates sink as they meet meaning the pressure of the plates causes the formation of fold mountains. The plates converge into each other from the conventional current pushing the plates together and then when the pressure is released there are frequent and violent earthquakes.

Question 10

Explain Destructive Margin

Answer 10

The convection currents push the two plates together causing one of the plates to subduct down underneath the other plate. The pressure builds underneath and the magma chamber piles up causing the volcano to explode.
