Detailed explanation-1: -Energy from the sun and the force of gravity drive the continual cycling of water among these reservoirs. As the water is heated, it changes state from a liquid to a gas. This process is called evaporation. As more energy is added to the water, the water molecules move faster and farther apart.

Detailed explanation-2: -Energy from the sun and the force of gravity drive the continual movement of water between pools. The sun’s energy causes liquid water to evaporate into water vapor. Evapotranspiration is the main way water moves into the atmosphere from the land surface and oceans. Gravity causes water to flow downward on land.

Detailed explanation-3: -The energy obtained by the sun is called solar energy. It is the driving force of the ecosystem.

Detailed explanation-4: -The driving force of the water cycle is the sun’s radiation, which drives the process of evaporation.

Detailed explanation-5: -The driving force for evaporation is the gradient of the water vapour pressure near the skin surface. The water vapour pressure is that part of the total pressure of the air that is caused by the molecules of water in it. The hotter the air, the more water it is capable of carrying.
