EVERYDAY SCIENCE

Detailed explanation-1: -Liquid water flows across land (runoff), into the ground (infiltration and percolation), and through the ground (groundwater). Groundwater moves into plants (plant uptake) and evaporates from plants into the atmosphere (transpiration). Solid ice and snow can turn directly into gas (sublimation).

Detailed explanation-2: -Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle. Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the earth.

Detailed explanation-3: -Precipitation takes one of two paths once on the ground. It runs over the surface into rivers, lakes or the ocean, and becomes surface water, or it soaks into the earth and becomes groundwater.

Detailed explanation-4: -Water drops form in clouds, and the drops then return to the ocean or land as precipitation-let’s say this time, it’s snow. The snow will fall to the ground, and eventually melts back into a liquid and runs off into a lake or river, which flows back into the ocean, where it starts the process again.

Detailed explanation-5: -As precipitation falls towards the earth, some of the water seeps into the ground, a process known as infiltration.
