SIZIF [17.4K]

Answer:C) either runs off to form rivers or filters down into underground aquifers

Explanation:Precipitation is any form of moisture which falls to the earth. This includes rain, snow, hail and sleet. Precipitation occurs when water vapour cools. When the air reaches saturation point (also known as condensation point and dew point) the water vapour condenses and forms tiny droplets of water.

In meteorology, precipitation is any product of the condensation of atmospheric water vapour that falls under gravity from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. ... Short, intense periods of rain in scattered locations are called "showers."

Compare and contrast alluvial fans and deltas.
ICE Princess25 [194]
Similarities :Both alluvial fans and deltas deposit sediment. Difference: A delta forms when a river empties into a larger body of water. An alluvial fan forms on land where a river emerges from a mountainous area and flows out onto a more gently sloping plain. The decrease in slope causes the river to decelerate and deposit sediment, forming an alluvial fan.
