Answer to Question 1

Answer: As cumulus clouds grow, they shade the ground from the Sun, which slows surface heating and inhibits upward convection of warm air. Without a continuous supply of rising air, the cloud begins to dissipate. Once the cloud is gone, the ground reheats, allowing the air above it to warm and rise. Thus convectional lifting begins again, and another cumulus cloud begins at the same place.
