Plate tectonics Flashcards
What causes earths plates to move?
Convection- causes the plates to move
What is a rift?
A rift is an ocean valley that appears a divergent boundaries
What are the three most popular plate boundaries?
Convergent, divergent, and transform boundaries
What happens at divergent boundaries?
Mid ocean ridges or rift valleys can occur
What occurs at convergent boundaries?
At convergent boundaries mountain ranges can occur
What happens at convergent boundaries?
Earthquakes appear at this type of boundary
What causes the tectonic plates to move?
Convection causes the plates to move
What is the only plate boundary that magma isn’t revolved in?
Magma does not appear at transform boundaries
What boundary is new crust formed at?
It is formed at divergent boundrys
What is the main difference in between conrvergent boundaries and divergent boundaries?
Convergent slides together and divergentsiledes apart
