SCIENCE WEEK 5 - CAUSES OF PLATE MOVEMENT

Question 1

it is a process where heat is transferred from one place to another

Answer 1

Convection

Question 2

the movement of energy from one place to another

Answer 2

Heat Transfer

Question 3

Proposed by Arthur Holms in 1929; Describe the movement of the mantle as it transfer heat from the white-hot core to the brittle lithosphere

Answer 3

Convection Currents

Question 4

are caused by a heated molten rock in the mantle becomes less dense and rise. At the same time other molten cools and become more dense so they sink.

Answer 4

Convection Currents

Question 5

Driving Forces of Plate Tectonics

Answer 5

Mantle Convection
Ridge Push
Slab Pull
Slab Suction

Question 6

is caused by gravitational force, and it exists because the ridge occur at a higher elevation than the rest of the ocean floor; a driving force for plate motion in plate tectonics that occurs at the mid-ocean ridges as the result of a rigid lithosphere slidingdown the hot, raised asthenosphere below mid-ocean ridges.

Answer 6

Ridge Push

Question 7

It is the force exerted by the weight of the subducted slab on the plate it is attached to; The denser plate sinks back into the mantle under the influence of the gravity. It pulls the rest of the plate along behind it.

Answer 7

Slab Pull

Question 8

occurs between two colliding plates, one subducting underneath the other, whereby convection currents in the upper mantle suck both plates down.

Answer 8

Slab Suction

Question 9

Resisting forces of the Plate Tectonics

Answer 9

Slab Resistance
Bending Resistance
Colliding Resistance
Transform Fault Resistance
