Water in the atmosphere typically returns to the surface of the Earth through the formation of clouds and precipitation. This means that the cycling of water from the atmosphere to the hydrosphere would be most likely to cause Rain.

Explanation:

Rain is the most common form of precipitation.

Other forms include snowfall , hail etc.

However, snowfall and hail require specific conditions and do not occur generally.

Snowfall is restricted to mountainous and colder regions where the rain drops freezes before reaching earths surface.

Again hail, which is seen even in tropical region occurs when the clouds reaches such heights or such cold regions in atmosphere that the droplets freezes to form ice and fall.

But usually the cloud become heavy enough before reaching such conditions to form hail so the water precipitate as Rain.

Thus we can say that the cycle of water from atmosphere to hydrosphere is most likely to cause Rain.
