the sky radiates solar matter into land & solar matter can warm up the land ->  the solar energy radiated by the ground can warm up air  if oil is heated then that oil will sunset & land is a mean of oil ->  if air is heated then air will rise  the solar energy radiated by the ground can warm up air & if air is heated then air will rise ->  the solar energy radiated by the ground can cause the air to rise  the solar energy radiated by the ground can cause the air to rise & eats up a want top is a mean of drop -> the solar energy radiated by the ground can cause the air to travel up a mountain side
