Plate Tectonics

Question 1

Convergent

Answer 1

Ex: plates = colliding
Features: collision between 2 plates destroys the lithosphere

Question 2

Convergent: Cont. vs Cont.

Answer 2

Ex: Himalayan mountains
Features: mountain range; highly deformed mélange of rock

Question 3

Convergent: Ocea vs Ocea

Answer 3

Ex: Mariana Islands, Japan
Features: Volcanic island; deep-ocean trenches; subduction zones

Question 4

Convergent: Cont. vs Ocea

Answer 4

Ex: Andres Mountains, Mount Saint Helens
Features: Volcanic arc; deep-ocean trenches; subduction zones

Question 5

Transform

Answer 5

Ex: plates= sliding past one another
Features: sliding of plates doesn’t create or destroy the lithosphere

Question 6

Transform plate boundary

Answer 6

Ex: San Andres fault zone of Western North America
Features: faults, earthquakes

Question 7

Divergent

Answer 7

Ex: plates=moving away
Features: result of both plates moving away creates new lithosphere

Question 8

Divergent: Cont. vs Cont.

Answer 8

Ex: East Africa rift valley, the red sea
Features: rift valley; new lithosphere created

Question 9

Divergent: Ocea vs Ocea

Answer 9

Ex: mid-atlantic ridge
features: rift valley; mid ocean ridge; new lithosphere created
