Ch.8- Plate Tectonics

Question 1

Convergent Boundary

Answer 1

A boundary along which two tectonic plates push together, characterized either by subduction or a continental collision

Question 2

Transfer Boundary

Answer 2

A boundary along which two tectonic plates scrape past each other, and crust is neither formed nor destroyed

Question 3

Rift Valley

Answer 3

A deep valley formed as tectonic plates move apart, such as along a mid- ocean ridge

Question 4

Magnetic reversal

Answer 4

A switch in the direction of earth’s magnetic field so that the magnetic North Pole becomes the magnetic North Pole

Question 5

Hot spot

Answer 5

An area where a column of hot material rises from deep within a planets mantle and heats the lithosphere above it, often causing volcanic activity at the surface

Question 6

Divergent Boundary

Answer 6

A boundary along which two tectonic plates move apart, characterized by either a mid-ocean ridge or a continental Rift Valley
