Hint: Earth has an abundance of water present. All this water is a result of the continuous water cycle between the oceans and the land. The amount of water will not change over a short span of time but will get affected in the long run.
Complete answer:
The water cycle consists of Evaporation, cooling, Freezing Condensation, and melting. The water cycle is also known as the Hydrological cycle which is a never-ending process of circulation of water from the oceans to the lands. The steps involved are:
Evaporation: The conversion of water from the oceans from liquid to water vapors due to sun’s heat is known as evaporation. This gaseous water forms the water vapor in the atmosphere. Huge amount of sun’s heat is required for this conversion.
Condensation: Water vapor is carried to a cool place by the ocean current, where it cools and forms clouds. This is known as condensation. The clouds are a collection of water droplets which have condensed from gaseous state to liquid state.
Precipitation: The discharge of water from the clouds in the form of rain, hail, snow due to the colliding clouds is known as precipitation. Precipitation leads to the water running off from the surface to the oceans again.
Hence the correct answer is Option B
Option A is incorrect because the oxygen cycle involves the formation of oxygen by the plans and generation of carbon dioxide by the animals.
Option C is incorrect because the Nitrogen cycle involves the fixation of nitrogen into the roots of the leguminous plants, by atmospheric factors.
And hence option B is correct.
Note:
Water cycle is responsible for the earth’s climatic changes and also exchange of energy between oceans and land. Due to the absorption of heat by the oceans the effect of the greenhouse gases is well managed.
