Question

Which of the following best defines the water cycle, also known as the hydrological cycle?

Cycling of hydrogen and oxygen that contributes 78% of atmospheric gases and drives food webs
Cycling of hydrogen and oxygen that involves changes between the solid, liquid, and gas phases
Cycling of water that contributes 78% of atmospheric gases and drives food webs
Cycling of water that involves changes between the solid, liquid, and gas phases

Answer 1

Cycling of water that involves changes between the solid, liquid and gas phases best defines the water cycle.

Explanation:

The water cycle explains the water is moving continuously in the earth's atmosphere is in three states that are solid, liquid and gas. The water keeps on moving from one kind of reservoir to a different type of reservoir. From the river to the ocean and from ocean to atmosphere.

The physical processes that take place in atmosphere are the evaporation, the condensation, the precipitation, the infiltration, subsurface runoff. In these different types of phases, you will be able to see water changes into three forms solid state, liquid state and gaseous state.

Answer 2

In water cycle the cycling of water brings changes between the liquid, solid and gas stages. Thus Option D is the right answer.

Step-by-step explanation:

Through hydrogen cycle water is continuously flowing in the atmosphere of Earth. This flowing of water is conducted in atmosphere through various methods, like- transpiration, evaporation, precipitation etc.

The best description of water cycle is that it brings changes between the solid, gas and liquid state of water. By evaporation liquid is changed into gas and sometimes solid too changes in vapour through sublimation.
