Week 6

Question 1

Its is a fault along a boundary where the motion is predominantly horizontal, two plates are sliding past each other. What does it form?

Answer 1

Transform plate boundary

Question 2

Rocks that line the boundary are pulverized as the plates grind along, creating what?

Answer 2

Linear fault valley or undersea canyon

Question 3

What are the types of transform plate boundaries

Answer 3

Ridge-ridge
Ridge-trench
Trench-trench

Question 4

Is a proposed driving pose for plate motion in plate tectonics that occurs at mid ocean ridges as the result if the rigid lithosphere sliding down the hot, raised asthenosphere below mid-ocean ridges. What type of transform plate boundary is it?

Answer 4

Ridge-ridge

Question 5

A mid oceanic ridge is an underwater mountain range formed by what?

Answer 5

Plate tectonics

Question 6

Deep trenches are formed when tectonic plates are being subducted and earthquakes are common. What type of transform plate boundary is it?

Answer 6

Trench-trench

Question 7

______ are formed by a subduction. What is it?

Answer 7

Trenches

Question 8

What type of transform plate boundary if a type of fault in which two tectonic plates slide past one another?

Answer 8

Ridge-trench

Question 9

Are areas where the Earth’s plates move past each other, rubbing along the edges. What is it?

Answer 9

Transform boundaries

Question 10

As the plates slide across from each other, they neither create land or destroy it. Because of this, they are sometimes referred to as……?

Answer 10

Conservative boundaries

Question 11

________ is the main driving force of plate tectonics.

Answer 11

Gravity

Question 12

Plate movements moves in a pattern called _______________ that forms when warm material rises, cools and eventually sinks down.

Answer 12

Convection cell

Question 13

The force that causes most of the plate movements is called _______ __________

Answer 13

Thermal convection

Question 14

A scientific theory describing the large scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth’s litosphere. What is it?

Answer 14

Plate movement

Question 15

Due to extreme temperatures inside the Earth what rises from the mantle at mid ocean ridges, thus pushing the plates apart?

Answer 15

Hot magma

Question 16

____________ occur along the fractures that appear as the plates move away from each other.

Answer 16

Earthquakes

Question 17

What is an example of plate movement?

Answer 17

East African Rift

Question 18

__________ where two ocean plates moved apart can be seen in some regions near the Azores and Iceland.

Answer 18

Mid-ocean ridges
