When water vapor in the air cools and turns into water droplets, it forms ___. A. clouds B. snow C. hail D. rain 相关知识点: 试题来源: 解析 A。当空气中的水蒸气冷却并变成水滴时,会形成云。snow 是雪;hail 是冰雹;rain 是雨。反馈...
In the process of cloud formation, the change from water vapor to liquid droplets is called ___. A. melting B. freezing C. condensation D. sublimation 相关知识点: 试题来源: 解析 C。解析:在云形成过程中,从水蒸气到液态小水滴的转变被称为凝结(condensation)。A选项“melting”(融化)是指固态...

The importance of the result to both deuterium and tritium rainwater measure- ments is far reaching and suggests that such observations ought to be supplemented with at- mospheric water-vapor samples. Iniroduction. The exchange of water vapor between a falling rain droplet and its environ- ment...
Cacti use CAM photosynthesis to survive the extreme heat and drought of the desert. Next, we'll look at how the hydrologic, or water, cycle functions. The Water Cycle Water vapor that ends up in clouds eventually condenses into water droplets and precipitates as rain, sleet, hail or snow...
hence is less dense. Due to the significant difference in density,buoyancydrives humid air higher. As altitude increases, air pressure decreases and the temperature drops. The lower temperature causes water vapor to condense into tiny liquid waterdropletswhich are heavier than the air, and fall unl...
The clouds are fluffy. This is because water vapor condenses and forms tiny droplets. The softness of the clouds is what makes them so inviting. The reason why the clouds are fluffy is that the droplets are small and light. The clouds are fluffy. This is ___. A...
Water in three states:liquid,solid (ice),and (invisible) water vapor in the air.Clouds are accumulations of water droplets,condensed from vapor-saturated air.Water is a chemical substance with the chemical formula H2O.Its molecule contains one oxygen and two hydrogen atoms connected by covalent ...
Graupelare soft, small pellets(颗粒状物) formed when supercooled water droplets (at a temperature below 0°C) freeze onto a snow crystal, a process called riming(结晶). If the riming is particularly intense, the rimed snow crystal can grow to anappreciablesize, but remain less than 0.2 inch...
As the water vapor goes high in the sky, the air gets cooler. The cooler air causes the water droplets(微滴) to stick to things like dust(粉尘), ice or se a salt.Clouds get their names in two ways. One way is by where they are found in the sky.Some clouds are high up in ...
