What's happening above those mountains? Several clouds are stacked up into one striking lenticular cloud. The water cycle is all about storing water and moving water on, in, and above the Earth.
Although the atmosphere may not be a great storehouse of water, it is the superhighway used to move water around the globe. Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents. Cooler temperatures aloft allow the vapor to condense into clouds and strong winds move the clouds around the world until the water falls as precipitation to replenish the earthbound parts of the water cycle.
About 90 percent of water in the atmosphere is produced by evaporation from water bodies, while the other 10 percent comes from transpiration from plants. There is always water in the atmosphere. Clouds are, of course, the most visible manifestation of atmospheric water, but even clear air contains water — water in particles that are too small to be seen.
One estimate of the volume of water in the atmosphere at any one time is about 3, cubic miles mi 3 or 12, cubic kilometers km 3.
That may sound like a lot, but it is only about 0. If all of the water in the atmosphere rained down at once, it would only cover the globe to a depth of 2. Do you think clouds have any weight? How can they, if they are floating in the air like a balloon filled with helium? If you tie a helium balloon to a kitchen scale it won't register any weight, so why should a cloud? To answer this question, let me ask if you think air has any weight—that is really the important question. If you know what air pressure and a barometer are, then you know that air does have weight.
Since air has weight it must also have density, which is the weight for a chosen volume, such as a cubic inch or cubic meter.
If clouds are made up of particles, then they must have weight and density. The key to why clouds float is that the density of the same volume of cloud material is less than the density of the same amount of dry air. Just as oil floats on water because it is less dense , clouds float on air because the moist air in clouds is less dense than dry air.
We still need to answer the question of how much a cloud weighs. To confuse things more, the weight depends on how you define it:. We're only going to look at the weight of the actual cloud particles. A 1 km 3 cloud contains 1 billion cubic meters. Doing the math: 1,,, x 0. That is about , kilograms or 1.
But, that "heavy" cloud is floating over your head because the air below it is even heavier— the lesser density of the cloud allows it to float on the dryer and more-dense air. The water cycle is defined as a natural process of constantly recycling the water in the atmosphere. It is also known as the hydrological cycle or the hydrologic cycle. During the process of the water cycle between the earth and the atmosphere, water changes into three states of matter — solid, liquid and gas.
The water cycle is often taught as a simple circular cycle of evaporation, condensation, and precipitation. There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration. How does water get from the atmosphere into the groundwater system?
Precipitation falls on the ground and infiltrates into the ground surface to fill pores and fractures. Sea level drops when water is stored in expanding ice sheets and continental glaciers. All the spheres interact with other spheres. For example, rain hydrosphere falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth biosphere.
Flooding rivers wash away soil. Matter can cycle through the biosphere because biological systems do not use up matter, they transform it. The matter is assembled into living tissue or passed out of the body as waste products. Simply put, biogeochemical cycles pass the same molecules around again and again within the biosphere. As it travels through food webs, nitrogen can leave as the organism dies and decomposes and eventually ends up back in the atmosphere as nitrogen gas.
Through this cycling, the atoms that make up all living and nonliving things are used and used again, making nature a most efficient recycler. How is the movement of matter through the biosphere different from the flow of energy? You just studied 29 terms!. Water enters the atmosphere through evaporation, transpiration, excretion and sublimation.
