Explain why heating an air mass causes it to rise.
 
  What will be an ideal response?

Question 2

Explain why the distribution of solar energy varies with latitude.
 
  What will be an ideal response?

Answer to Question 1

When an air mass is heated, its density becomes lower than that of its surroundings, and buoyancy causes lower-density air to rise.

Answer to Question 2

Due to the curvature of Earth, the radiation reaching Earth at high latitudes is spread over larger areas than is the radiation reaching Earth at low latitudes. Each square meter of the surface receives proportionately less energy as we move to the higher latitude, and incoming solar flux thus decreases from the equator toward the poles.
