Possible Causes Of Plate Movement

Question 1

The american geophysicist who proposed the theory of sea floor spreading in 1960

Answer 1

Harry H. Hess

Question 2

states that the division of pangea is caused by the spreading apart of oceanic plates

Answer 2

Theory of sea floor spreading

Question 3

when the oceanic plates diverges, it creates a gap where magma from mantle can rise up and occupy the ridges which causes the movement.

Answer 3

Theory of sea floor spreading

Question 4

Force that causes the movement of plates

Answer 4

Drivinf force

Question 5

Enumerate the 3 driving forces of plate movement

Answer 5

Mantle convection, ridge push, slab pull

Question 6

Warm mantle currents drive and carry plates of lithosphere along like a conveyor belt

Answer 6

Mantle convection

Question 7

It pushes away the magma released from the mantle

Answer 7

Ridge push

Question 8

Empty space between the divergence of plates

Answer 8

Ridge

Question 9

It happens when the magma is hot enough and goes up and when it cools down, it sinks

Answer 9

Mantle convection

Question 10

It happens between the subduction zone

Answer 10

slab pull

Question 11

It happens when the sinking plate pulls the plate along it

Answer 11

Slab pull

Question 12

force that opposes the plate movement

Answer 12

Resisting force

Question 13

The force acts as a plate collided with another plate

Answer 13

Slab resistance

Question 14

Directly opposes the slab pull

Answer 14

Collisional resistance

Question 15

Resists all driving force

Answer 15

Slab resistance

Question 16

It opposes ridge push

Answer 16

Transform fault resistance

Question 17

Operates on almost all parts of moving lithosphere

Answer 17

Drag force

Question 18

Considered the main reason why continental drift is discarded

Answer 18

drag force

Question 19

3 evidences that support plate movement

Answer 19

1. The continents fit together almost like puzzle pieces forming Pangea
2. Similarities of fossils from 1 continent to another.
3. Similarities of geological features like plate boundaries
