Question 18

What does the crust and the upper mantle make?

Answer 18

The crust and upper mantle are hard and they form the lithosphere

Question 19

Below the lithosphere

Answer 19

The rock below the lithosphere is hot, soft and moving. Currents called convection currents of hot rock rise very slowly, cool and sink again these currents are son powerful that they move the earths crust around.
