Does the water cycle cause rain?
Frequent and detailed measurements help scientists make models of and determine changes in Earth’s water cycle. The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.
What phase of the water cycle contains rain?
When molecules of water vapor return to liquid or solid form, they create cloud droplets that can fall back to Earth as rain or snow—a process called condensation. Most precipitation lands in the oceans.
Does the water cycle happen all the time?
Earth’s water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth.
What causes the water cycle to keep happening?
The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. 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.
What happens to water vapor in the rain cycle?
When the sun heats the water in the lakes, streams, oceans, etc. some of it turns to a gas (water vapor). This is called evaporation. This invisible water vapor is light and rises into the air. When the water vapor hits the cold air high up in the atmosphere it turns back to water droplets and collects in clouds.
How is the water cycle related to the hydrologic cycle?
The water cycle is also known as the “ hydrologic cycle “. When too much water has condensed, the water droplets in the clouds become too big and heavy for the air to hold them. And so they fall back down to Earth as rain, snow, hail or sleet, a process known as “ precipitation “.
Why are rain and snow important in the water cycle?
Rain and Precipitation. Rain and snow are key elements in the Earth’s water cycle, which is vital to all life on Earth. Rainfall is the main way that the water in the skies comes down to Earth, where it fills our lakes and rivers, recharges the underground aquifers, and provides drinks to plants and animals.
How to make a rain cycle science experiment?
If desired, draw water, a cloud, and a sun on the Ziploc baggie with a marker. Add a small amount of water to the baggie without getting the sides wet. Add a few drops of blue food coloring to the water (optional). Hang on a sunny window for several hours.
