What part of the water cycle is occurring at point b

The correct answer would be precipitation.

Water cycle or hydrologic cycle refers to the cyclic movement of water in an ecosystem.

It involves various stages such as evaporation, condensation, precipitation, surface runoff and infiltration.

During precipitation, water from the cloud precipitate or fall down on the surface of Earth in the form of rain, snow, fog drip, hail et cetera. It occurs when water droplets combine with each other to larger droplets. Being larger or heavier they fall off on the ground in the form of rain. In addition, when the temperature is too low, then these droplets fall off as snow.

Precipitation also takes place when air is unable to hold any more water.

Part is evaporation and part c is surface run off.

true is the final answer!

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
