• Combination of various factors

• Only magnetic forces

• Only gravitational effects

What is the term used to describe the process of heat transfer in fluids?

• Radiation

• Conduction

• Diffusion

• Convection

What is the state of the mantle where convection currents occur?

• Gas

• Plastic-like

• Solid

• Liquid

What causes the material in the mantle to move upwards?

• It cools down

• It becomes denser

• It becomes hotter and less dense

• It gains gravitational pull

How do convection currents in the mantle affect the lithosphere?

• They cause the lithosphere to melt

• They push the lithosphere upwards only

• They have no effect on the lithosphere

• They drag the lithosphere along with them

What is the speed of convection currents in the mantle compared to boiling water?

• Faster

• No movement

• Same speed

• Slower

What happens to lithospheric plates as they move away from the ridge?

• They become thinner

• They remain the same

• They become denser

• They become lighter
