Drifting Continents and Spreading Seas - Plate Tectonics

Question 1

Tectonic plates

Answer 1

Large slabs of the lithosphere (outermost layer of the earth)

Question 2

Plate boundary

Answer 2

Where 2 or more tectonic plates meet and where most earthquakes and volcanos occur

Question 3

Continental drift

Answer 3

The theory that the earth’s continents move over time

Question 4

Divergent plate boundary

Answer 4

Where 2 tectonic plates move in opposite direction of one another and as a result, magma from the earth rises to form a new crust (outer layer of the earth)

Question 5

Convergent plate boundary

Answer 5

Where 2 tectonic plates move towards and collide with one another resulting in a crust being destroyed and subduction (when one tectonic plate slides below another tectonic plate). It may result in earthquakes and volcanoes.

Question 6

Transform plate boundary

Answer 6

Where 2 tectonic plates slide past each other causing shallow earthquakes

Question 7

Continent

Answer 7

Large piece of land
