Clouds: Man-Made

By Janice VanCleave

There are many types of clouds in the sky, some are even man-made, such as the clouds left by airplanes as they fly by. The name of these man-made clouds is contrail (short for “condensation trail”). Contrails are vaporized water that condenses. Condensation is a process by which water vapor is cooled resulting in the […]

Energy: Atmosphere Model

By Janice VanCleave

A model represents something. For example, a model airplane is a replica of some real airplane, but much smaller. A model can also represent how something behaves, such as a closed jar represents how Earth’s atmosphere keeps Earth warm. This is done because the atmosphere, a blanket of air that surrounds Earth, traps heat leaving […]

Acid Rain: Man Made

By Janice VanCleave

Sulfur oxides are gases released when fossil fuels (coal and oil) are burned. Large amounts are released when industries and power plants burn fossil fuels.The diagram shows two sulfur oxides: sulfur dioxide sulfur trioxide The main source of nitrogen oxides is from the exhaust of vehicles. Nitrogen oxides and sulfur oxides in air react with […]
