Direction of Plates
Divergent Boundaries
What are the effects of a convergent subduction boundary?
Ocean trenches off the coast of the continental plate, Volcanoes on the continent near the coast, destruction of the oceanic plate
Which plates has trenches as an effect?
At what rate do plates move?
They move really slow
What happens to the mantle when a divergent boundary occurs?
After the plates separate a ridge goes through the Middle, the mantle starts to harden.
What kind of plate moves towards each other?
Convergent Boundaries
What are the effects of a convergent collision boundary?
Folds and faults, mountain ranges, shallow earthquakes, shortening and thickening of plates in collision zone
What plate has an effect of underwater mountain ranges?
Divergent Plate Boundaries.
Soft, solid
Which boundary makes trenches?
Convergent Boundary
What kind of plate boundary slides past each other side by side?
Transform Boundaries
What are the effects of a divergent boundary?
Underwater mountain ranges such as the Mid-Atlantic Ridge; volcanic eruptions through cracks in the crust,creation of new seafloor and a widening ocean basin.
What type of land form is created from the divergent boundary in Africa?
The Great Rift Valley
What type of plate boundary created earth?
Divergent Boundary
How many types of boundary have mountains or ridges?
Convergent collision, Divergent boundary
What kind of continental boundary created mountains when they collide?
Convergent Collision Boundaries
What are the effects of a transform boundary?
Does not create or destroy land, earthquakes, movement of large rocks, and deformation of Earth’s crust
What plate boundary does not create or destroy land?
Transform Boundary
What type of plate boundary destroyed earth?
Convergent Boundary
What does one plate go underneath in a subduction boundary?
Is the less dense or the more dense plates move under in a convergent subduction boundary?
More Dense plate will sink to the bottom.
What plate has an effect of underwater mountain ranges, such as mid-Atlantic ridges?
Divergent Boundaries
What plate has the seafloor moving away with the plates?
Divergent Boundary
What happens to the mantle when a convergent collision boundary happens?
It sinks because the oceanic plate collides with the continental plate. The plate gets pushed under the other plate, causing the mantle to go deep.
Describe the density in the convergent collision boundary.
