Continental Drift and Plate Tectonics

Front

What are transform boundaries?

Back

Transform boundaries are places where two tectonic plates slide past each other, often causing earthquakes.

Front

What phenomenon is most likely produced by transform boundaries?

Back

Earthquakes.

Front

What happens at a converging boundary between two pieces of continental crust?

Back

A folded mountain range is produced.

Front

What is the hypothesis that states the continents were once joined to form a single supercontinent?

Back

Continental drift.

Front

What was the name of the supercontinent in the continental drift hypothesis?

Back

Pangaea.

Front

According to Wegener's hypothesis of continental drift, what happened to the continents?

Back

The continents were once joined together in a single landmass.

Front

What is plate tectonics?

Back

Plate tectonics is the scientific theory that describes the large-scale movements of Earth's lithosphere, which is divided into tectonic plates.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What are the three types of plate boundaries?

Back

Divergent, convergent, and transform boundaries.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics, where new oceanic crust is created.
