Plate Movement.
What makes plates move?
Heated magma currents.
How do convection currents move.
The magma attached to the crust with the magma moves by the convection currents.
What is a transform boundary?
Where the crust is neither produced or destroyed.
Types of trenches made by transform boundaries.
Deep Trenches.
How do earthquakes happen?
When plates are pushed together, called convergent boundaries.
Why do plates move?
What are convection currents?
What is a divergent boundary?
New crust is generated while the other is pulled away.
What submarine mountain range is created by divergent boundary?
Mid-Atlantic Ridge.
Divergent Boundaries cause volcanic eruptions how?
The plates continuously move the magma up from mantle.
Types of plate boundaries.
Divergent, Convergent, and Transform.
What is the heat source for convection in the mante?
The core.
What type of plate boundaries is the oceanic-oceanic boundaries?
Convergant.
What is one thing that other boundaries don't create that convergent boundaries create?
Volcanoes.
What boundaries create tsunamis?
Convergent Plate Boundaries.
Spreading ridges.
How does the convection currents in the mantle affect the crust?
The crust moves in the same directions.
What type of plate boundaries is a oceanic-continental boundaries?
Convergent.
What happens when a transform boundary connects two diverging boundaries?
A Fault Line
What cause landslides?
When a convergent boundary causes an earthquake.
What does a transform boundary cause.
Valleys and Ponds.
What layer of the earth changes because of the convection cycle.
The crust.
What type of plate boundaries is a continental - continental boundaries?
Convergent.
What happens when two continental plate boundaries converge?
A mountain range is created.
How did Pangea occur?
The plate boundaries started to move and the continents began to drift.
