Detailed explanation-1: -The water cycle does not have a real starting or ending point. It is an endless recycling process that involves the oceans, lakes and other bodies of water, as well as the land surfaces and the atmosphere. Water enters the atmosphere by evaporation and transpiration, and water returns to land by precipitation.

Detailed explanation-2: -There is no start or end to the water cycle, but for explanation purposes we will start at the sun. Solar radiation from the sun heats the ocean and causes evaporation. This water vapor then enters the atmosphere. As it reaches the upper atmosphere, it cools and condenses forming clouds.

Detailed explanation-3: -Step 1: Evaporation The first of the water cycle steps begins with evaporation. It is a process where water at the surface turns into water vapors. Water absorbs heat energy from the sun and turns into vapors. Water bodies like oceans, seas, lakes and rivers are the main source of evaporation.

Detailed explanation-4: -The Water Cycle is the continuous circulation of water between the earth and the atmosphere. It has no starting or ending point. As water moves through this cycle, it changes forms.

Detailed explanation-5: -Photosynthesis is actually the process in the plants where the sunlight, Carbon dioxide and water are converted into the organic compounds such as starch, energy and Oxygen and so this is the process which is not involved in the water cycle.
