Rain

A:

Rain and other forms of precipitation fall from the clouds. When warm air passes over a body of water, it causes the water to evaporate. Once the water rises high enough, it clumps with other water vapor and becomes a cloud. The air cannot hold an infinite quantity of water, so when the amount of water present in the cloud exceeds the air’s ability to hold it, the water falls in droplets as rain.

  • How does elevation affect precipitation?

    Q: How does elevation affect precipitation?

    A: Areas of high elevation, such as mountain ranges, often drain the air of its moisture. As the air rises up the mountain, it cools. As the air cools, it loses its ability to hold water. The water then condenses out of the air and falls as precipitation.

  • Why is the water cycle important to life on earth?

    Q: Why is the water cycle important to life on earth?

    A: The water cycle is responsible for distributing water across the earth through evaporation, condensation and precipitation, a process that is vital for sustaining life on earth by providing water to plants, animals and humans. It is also the driving force behind the earth's climate. Clouds are formed through condensation, and temperature is regulated through evaporation and water vapor in the air.

  • What causes rain to fall?

    Q: What causes rain to fall?

    A: Rain falls when atmospheric water vapor falls under gravity. In other words, when the water vapor in the atmosphere becomes too heavy, rain falls.

  • How do droughts form?

    Q: How do droughts form?

    A: Put simply, droughts are caused by a prolonged depletion of precipitation in a certain ecosystem or climate over a long period of time. Unlike normal dry spells, droughts are so severe that they can thoroughly dry out vast expanses of land, like deserts. Droughts can be extraordinarily damaging and expensive to the people who live in the environments where they occur, especially in terms of the agricultural industry.

  • What causes rain?

    Q: What causes rain?

    A: Any time the droplets in clouds grow and come together to form drops that are large enough to create a speed of falling that is greater than the speed at which the cloud is blowing upward, then they head downward, and if they make it down without evaporating, people on the ground experience them as rain or snow. Sometimes rain evaporates again and heads back up into the clouds. The greater the amount of water vapor under the cloud and the stronger the winds on the updraft, the more likely precipitation becomes.

  • What are some examples of condensation?

    Q: What are some examples of condensation?

    A: Some examples of condensation include the water that gathers on a bathroom mirror after a hot shower and the water that collects on grass as dew. Condensation is the process where gas molecules slow down and come together to form a liquid.

  • Q: What can you learn from a ZIP code map showing rainfall history data?

    A: A ZIP code map with rainfall history data shows the average rainfall over a specified period of time. The rainfall overlay demonstrates the rainfall distribution, so you can learn which areas of the ZIP code get the most rainfall. If the map features a topography layer, you can also learn how rainfall averages vary from high points to low points.

  • Q: How do droughts occur?

    A: According to About.com, there are many causes for drought, but the most important one "relates to the amount of water vapor in the atmosphere, as this is what creates precipitation." Moist, low pressure systems tend to bring more rain, snow, sleet and hail, while dry high pressure systems lead to a lack of precipitation.

  • Q: What does acid rain affect?

    A: Acid rain causes acidification of bodies of water such as lakes and streams. It can also contribute to damage to trees at high elevations and forest soils. Also, the decay of buildings is accelerated, as paint and building materials are eaten away by acid rain. Statues and monuments are susceptible to the damage done by acid rain, resulting in damage to their finish.
