According to the geothermal gradient, there is an increase in temperature with increasing depth. If that is the case, why isn't the entire interior of the planet molten?
 
  What will be an ideal response?

Question 2

Is the force of gravity the same over the Earth's surface? Explain why or why not.
 
  What will be an ideal response?

Answer to Question 1

Answer: The great internal pressure of the Earth raises the melting point of the minerals.

Answer to Question 2

Answer: The acceleration due to gravity is not the same over the planet. It is less at the equator than at the poles because the planet bulges out farther at the equator. This oblate spheroid shape is the result of rotation.
