Question

How does it rain?

Answer 1

Water falls from the sky! Of Corse!

Answer 2

The water cycle has no starting or ending point. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Ice and snow can sublimate directly into water vapor. Rising air currents take the vapor up into the atmosphere, along with water from evapotranspiration, which is water transpired from plants and evaporated from the soil. The vapor rises into the air where cooler temperatures cause it to condense into clouds. Air currents move clouds around the globe, cloud particles collide, grow, and fall out of the sky as precipitation. Some precipitation falls as snow and can accumulate as ice caps and glaciers, which can store frozen water for thousands of years. Snowpacks in warmer climates often thaw and melt when spring arrives, and the melted water flows overland as snowmelt. Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff. A portion of runoff enters rivers in valleys in the landscape, with streamflow moving water towards the oceans. Runoff, and ground-water seepage, accumulate and are stored as freshwater in lakes. Not all runoff flows into rivers. Much of it soaks into the ground as infiltration. Some water infiltrates deep into the ground and replenishes aquifers (saturated subsurface rock), which store huge amounts of freshwater for long periods of time. Some infiltration stays close to the land surface and can seep back into surface-water bodies (and the ocean) as ground-water discharge, and some ground water finds openings in the land surface and emerges as freshwater springs. Over time, the water continues flowing, some to reenter the ocean, where the water cycle renews itself. So the rain never ends.

Answer 3

there are three main kinds of rain which are classified by the way in which the air is cooled. Conventional rain occurs in warm regions. the Sun evaporates moisture which rises in strong convection currents of hot air. cooling of the air leads to the formation of cumulonimbus (rain) clouds.

in equatorial regions, convectional is often a daily occurrence. the land is heated in the morning, clouds form in the afternoon, and rain falls during a thunderstorm, approximately the same time every day.

Cyclonic rain occurs in depressions (low pressure air systems). clouds form when warm air is forced above cold, dense air.

Orographic rain occurs when air currents rise over mountain ranges. the rising air cools and clouds form. rain then falls on the mountain slopes

Answer 4

Water evaporates from lakes, rivers, etc. and condenses into clouds.  Eventually, given the correct meteorological conditions, the water will form larger droplets and fall to the earth as rain.
