Why is precipitation important to the water cycle?
A
It returns the water back into the oceans, lakes and rivers
B
It replenishes groundwater stored in aquifers
C
It returns water to the Earth
D
All of the above
Explanation: 

Detailed explanation-1: -Rain and snow are key elements in the Earth’s water cycle, which is vital to all life on Earth. Rainfall is the main way that the water in the skies comes down to Earth, where it fills our lakes and rivers, recharges the underground aquifers, and provides drinks to plants and animals.

Detailed explanation-2: -Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the earth. It comes in many forms, like rain, sleet, and snow.

Detailed explanation-3: -Precipitation is water that falls from the atmosphere to the Earth’s surface. Infiltration is precipitation that soaks into the soil. Runoff is precipitation that does not soak into the soil but instead moves on the Earth’s surface toward streams. Streamflow is water moving across the Earth’s surface in streams.

Detailed explanation-4: -Rain is the most widespread and most important form of liquid precipitation. its water droplets are large, usually over 0.5mm in diameter.

Detailed explanation-5: -Importance of hydrological cycle: As water undergoes infiltration, the ground purifies it of pollutants and contaminants. The water cycle continually feeds freshwater to all life on the planet. Rainfall and surface runoff play important roles in the cycling of various elements, also known as the biogeochemical cycle.
