Evaporated from the oceans, water vapor forms clouds, some of which are transported by wind over the continents. Condensation from the clouds provides the essential agent of continental erosion; rain. Precipitated onto the ground, the water trickles down to form brooks, streams, and rivers, ...
How does rain form? Let me introduce for you. Rain is a drop of water falling from the clouds, when the sun is shining and the air is warm, water vapor will evaporate and become moist air. The water vapor condenses in the sky, an...
Why are clouds generally observed to form in the troposphere? Why are clouds flat on the bottom? How is rain formed in the water cycle? Why does the polar jet stream cause rain? Why does oil not dissolve in water? What is caused by the condensation of water vapor?
time the snowflake encounters water vapor, more molecules attach to it, leading to more and more complex structures—and, of course, each snowflake takes a unique route through the clouds, on its way down…and so the quantity of water vapor it goes through is gonna be unique for each ...
Why is ice the solid form of water? Why can't cold air hold much water vapor? Why is evaporation a cooling process? Why does water cool when it evaporates? Why are clouds puffy? Why is transpiration important? Why must water evaporate for sedimentary rock to form?
Precipitation occurs when these water droplets in clouds become heavy enough to fall back to Earth as rain, snow, sleet or hail. Water vapor also acts as a greenhouse gas, trapping heat in the atmosphere and playing a significant role in regulating the Earth’s temperature. Without water vapor...
Clouds form when the temperature becomes too cold for the air to hold water vapor. The vapor condenses into tiny droplets. Scientists have measured thedensityof a cumulus cloud at about 0.5 grams per cubic meter. Cumulus clouds are fluffy white clouds, but the density of clouds depends on th...
And, of course, each snowflake takes a unique route through the clouds on its way down…And so the quantity of water vapor it goes through is gonna be unique for each one. Now, one important characteristic of snowflakes is that they have something called a quasi-liquid layer, the QLL....
Those sensations are water vapor.我们感觉到的这些都是水蒸气。If you put steam or vapor under the microscope, you would see millions of tiny water droplets floating in the air.如果在显微镜下观察水蒸气,我们能看到数以百万计的小水滴漂浮在空气里。This is the same process that forms clouds - ...
Gas rises into the air and forms clouds.Sometimes it even forms fog.38. According to the passage and the picture, which statement is FALSE ? A. Air temperature and wind patterns decide the type of precipitation. B. Precipitation is what happens when the water vapor evaporates. C. A cycle...
