Precipitation occurs when water is released from the clouds in any form. Water gets recycled on the Earth as a result of the water cycle where water evaporates, condenses and then falls as precipitation.Know More
The sun heats up the water from oceans, lakes and rivers. The water then evaporates, with the water vapor rising into the air and condensing into water droplets that form clouds. When these water droplets can no longer stay airborne, they fall as rain, sleet, hail or snow.
Much of the precipitation that falls to Earth is in the form of rain. The most rain that ever fell during a year occurred in India in 1861. Arica, Chile, holds the record for not receiving any type of precipitation for 14 years.Learn more about Earth Science
Fossils form when a dead animal or plant is covered by sediment. Eventually, the organic matter in the bone or plant, such as the blood vessels and tissue, slowly turns into rock, which becomes known as a fossil.Full Answer >
Rainbows form when water in the air reflects and refracts sunlight and disperses the normally white sunlight into colored light. White light is composed of colored light that bends at different angles when reflected and refracted, separating the white light into the distinct colors of a rainbow.Full Answer >
A glacier forms when a specific environment gets consistent snowfall throughout the year, causing the snow to accumulate rather than melt. The accumulation and compacting of snow by pressure eventually becomes glacial ice. Thus, sufficient moisture in the air and cold air are instrumental in the formation of glacier.Full Answer >
Deserts form in general from the high atmospheric pressure and cold air that comes from the upper altitudes nearby. The heat from the sun causes high ground temperatures with low humidity.Full Answer >
