Question 3

Describe the Lithosphere

Answer 3

• The crust and the upper mantle.

- Where earthquakes begin

Question 4

What is the movement of the heat transfer in the Earth caused by?

Answer 4

Convection caused by heat in the core

Question 5

What would happen to the flow of hot rock in the earths mantle of the planets core cooled down?

Answer 5

• The flow would stop.

- The mantle and plates will stop moving

Question 6

How would plate tectonics be effected if the flow of hot rock stopped and the mantle and plates stopped moving in the earths core?

Answer 6

There would be no earthquakes or volcanos.

Pieces of the Earths lithosphere are in constant, slow motion, driven by convection currents in the middle

Answer 7

The theory of plate tectonics
