Plate Boundaries and Plate Tectonics Unit 2 Part 1 Review 11.18

Front

What was a major criticism of Wegener's theory of continental drift?

Back

He could not explain how the continents moved.

Front

What evidence supports the idea that continents were once connected?

Back

Fossil evidence suggesting that the continents were connected.

Front

What is a subduction zone?

Back

A region where one tectonic plate sinks below another.

Front

What type of boundary is formed when two continental plates collide?

Back

A convergent boundary, which can form folded mountains.

Front

At what type of boundary do plates move towards one another?

Back

Convergent boundaries.

Front

What are the three main types of plate boundaries?

Back

Divergent, convergent, and transform boundaries.

Front

What geological features are commonly associated with divergent boundaries?

Back

Mid-ocean ridges and rift valleys.

Front

What happens at transform boundaries?

Back

Plates slide past each other, causing earthquakes.

Front

What is the process of sea-floor spreading?

Back

The formation of new oceanic crust at mid-ocean ridges as tectonic plates move apart.

Front

What is the Ring of Fire?

Back

A major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.
