Clouds are part of the Earth's water cycle. Formed naturally due to the cooling of water vapor within the Earth's atmosphere, clouds are made up of billions of water particles. Clouds take on many shapes and forms, dependent on local weather systems and local terrain. Some of the most co...
Low clouds like stratus and stratocumulus have flat bases and form when the air near the Earth's surface is cool enough to create condensation (water vapor in the air turns into liquid water droplets). High clouds like cirrus or cirrostratus have wispy bases....
or one that allows the full and free exchange of both matter and energy with its environment. The human circulatory system is an example of an open system, as are the various "spheres" of Earth (geosphere, hydrosphere, biosphere, and atmosphere) that we discuss later in this ess...
Some of the testing has been carried out in extreme conditions such as those the balloons might face in the atmosphere. At one point, temperatures fortuitously dropped to sub-freezing temperatures in South Dakota, one of the balloon manufacturing locations. More recent testing was done at the Mc...
Even though it isn’t the closest planet to the Sun, it is the hottest. On Venus, metal would melt into puddles of liquid! Venus is a rocky planet with a thick atmosphere of carbon dioxide and clouds made of sulfuric acid. Our hands-on activity for this section is to create our very...
in the solar nebula, out of Earth's interior. Erupting in great clouds from volcanoes-a process called "out gassing”一the water vapor condensed and rained out of the atmosphere. Gradually, according to this idea, over hundreds of millions or even billions of years, the oceans were created....
Human beings are not aware of the loss of resources. Lets imagine that if every person in China wastes a drop of water every day, then 1.4 billion drops of water will be wasted every day! If people are used to build fertile fields or arid areas, how many fields will grow agricultural ...
Ozonation: Ozone gas (the same type found in the atmosphere), typically created by subjecting oxygen to electrical current, is an antimicrobial agent — it kills microorganisms. The water is infused with ozone (03) molecules as a disinfecting process, and the molecules naturally break down and ...
In spring, fog can be a good thing in the form of low clouds which hold in heat and reduce chances for frost. It is in spring that we should pay even more attention to fog if we are growing plants for food or enjoyment. Fog forming early in low areas is a bad sign if you are ...
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, the planet would be much colder and less hospitable. Where Does Humidity Come From? Humidity is a natural part of our atmospher...
