1
Q

Name four different types of plate boundaries.

A

Conservative.
Constructive.
Destructive: Subduction and Collision.

2
Q

Explain how a destructive plate boundary is made.

A

Occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate.

3
Q

Explain how a collision plate boundary is made.

A

Collision zones form when two continental plates collide. Neither plate is forced under the other, and so both are forced up and form fold mountains.

4
Q

Explain how a constructive plate boundary is made.

A

A constructive plate boundary occurs when plates move apart. Volcanoes are formed as magma wells up to fill the gap, and eventually new crust is formed.

5
Q

Explain how a conservative plate boundary is made.

A

A conservative plate boundary occurs where plates slide past each other in opposite directions, or in the same direction but at different speeds.
