GEOLOGY

Detailed explanation-1: -Most surface water originates directly from precipitation in the form of rainfall or snow. Ground water from springs and seeps also contribute to flow of most of the streams.

Detailed explanation-2: -Precipitation and water runoff feed bodies of surface water. Evaporation and seepage of water into the ground, on the other hand, cause water bodies to lose water. Water that seeps deep into the ground is called groundwater. Surface water and groundwater are reservoirs that can feed into each other.

Detailed explanation-3: -The ocean is the largest source of water. It covers 70 % of the surface of the Earth and 97 % of the Earth’s overall water content.

Detailed explanation-4: -Rainwater is the main source of groundwater. Rainwater recharges the groundwater through the process of the water cycle. Groundwater is one of the important sources of water in our country.

Detailed explanation-5: -Most groundwater comes from precipitation. Precipitation infiltrates below the ground surface into the soil zone. When the soil zone becomes saturated, water percolates downward. A zone of saturation occurs where all the interstices are filled with water.
