tectonic plates
Two plates moving towards each other are called convergent plates. Which structures are likely to form at a convergent plate boundary?
Question 2 options:
rift valley
wave erosion
mountains
river canyons
mountains
When oceanic and continental plates converge, the oceanic plate tends to go under the continental plate where the plate eventually melts. Which feature below forms at these types of boundaries?
Question 4 options:
rift valley
seafloor spread
volcanic mountains
folded mountains
volcanic mountains
Wegner's idea of plates moving was not accepted until it was determined how they could move. It is now thought that plates move due to ______________ in the Earth's mantle.

What is the theory of Plate Tectonics?
Question 7 options:
A large plume of hot mantle material rising from deep within the Earth
A deep central fracture found along the crest of the mid-ocean ridge. On land, an elongated valley that overlies a region of stretching crust
A time when Earth's continents were once combined in one supercontinent
