All forms of water that comes down on Earth, including rain, snow, hail etc. is known as _____________

Calcification
Fixation
Precipitation
Accumulation

The correct answer is C. Precipitation.

Precipitation is any form of water that falls from the sky to the Earth’s surface. It includes rain, snow, sleet, and hail. Precipitation is caused by the water cycle, which is the continuous movement of water on, above, and below the Earth’s surface.

Calcification is the process of depositing calcium carbonate, a mineral that is found in limestone and other rocks. Fixation is the process of converting something into a fixed or stable state. Accumulation is the process of collecting or gathering something over time.
