Question

One of the following processes is not a step involved in the water-cycle operating in nature:

• A. evaporation
• B. transpiration
• C. precipitation
• D. photosynthesis

Answer 1

The correct option is D

photosynthesis

The correct option is (D):

Explanation for the correct answer:

Photosynthesis:

1. So basically in a water cycle , water will first rise into the air from water surfaces on the land by the process known as evaporation .
2. And further as the water will cool down in the atmosphere it will get condensed to form the clouds.
3. This water will return back to the earth's surface in the form of rain or snowfall which is actually known as precipitation.
4. This water will get refilled again and recharge back to the water bodies on the earth like the rivers, lakes and oceans .
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.

Explanation for the incorrect answers:

Option (A): Evaporation

1. Evaporation is basically the surface phenomenon where the water is changed from its liquid phase to the gaseous phase.
2. It is involved in the water cycle.
3. Hence, it is the incorrect option.

Option (B): Transpiration

1. This is actually the evaporation or the loss of water in the form of water vapors from the plants.
2. It mainly occurs through the stomata of the plants and is also involved in water cycle.
3. Hence, it is the incorrect option.

Option (C): Precipitation

1. It is basically the process of a water cycle in which the water will get released from the clouds.
2. The water is released from the clouds in the form of rain, snow, hail onto the surface of earth.
3. hence, it is the incorrect option.

Therefore, the correct option is(D): Photosynthesis
