Evidence of Plate Tectonic

Question 1

The (concept) and the internal heat of the earth have generated several forces that enables plate to move.

Answer 1

temperature difference

Question 2

Hot or warm viscous material in the mantle drives and carries tectonic plates.
-This driving force moves parts of the lithosphere along like a conveyor belt.

Answer 2

Mantle Convection

Question 3

Transfer of thermal energy by the movement of heated matter.

Answer 3

Convection

Question 4

An underwater water range

Answer 4

Mid-oceanic ridge

Question 5

The earth’s lithosphere solidifies and thickens because it cools as it moves away from the ridge.

The lithosphere is moved upwards by the asthenosphere because of the convection current.

Answer 5

Ridge push

Question 6

“Pulling force” applied by the cold and dense oceanic plate along subduction zones.

The denser plate sinks into the asthenosphere.

Answer 6

Slab Pull

Question 7

Driving mechanisms that create plate motion

Answer 7

Mantle convection, ridge push, and slab pull

Question 8

Slab pull and ridge push

Answer 8

Gravity-driven

Question 9

Mantle convection

Answer 9

Heat-driven

Question 10

An area within the mantle where rocks melt to generate magma

Answer 10

Hotspot

Question 11

Cylindrical passage-like column
It is fixed in the position where it is formed.
Hawaiian Hotspot
The plates on top of it may melt due to convection

Answer 11

Mantle Plume

Question 12

Used to track the movements of tectonic plates in real-time
Recorded by geologist
It is applied to different barriers and it can also be near a fault.

Answer 12

Global Positioning System
