Depending on the layer of the atmosphere, the temperature can either decrease or increase at rising altitudes. The five layers of the atmosphere, from lowest to highest, are the troposphere, the stratosphere, the mesosph... More »

As altitude increases, the air pressure decreases. The surface of the earth is the bottom of an ocean of air. The layers on top increase pressure so that at sea level a body is under 14.7 pounds of pressure per square in... More »

In general, matter expands with rising temperature, which leads to a fall in density. However, there are important exceptions, such as the case with water when it transforms from the solid to the liquid state. Its molecu... More »

Air cools when it rises through the atmosphere because as altitude increases, air pressure decreases and allows the individual air molecules to expand away from each other. This expansion leads to a decrease in collision... More »

When altitude increases, air temperature decreases. This is because, with an increase in altitude, there is a decrease in air pressure. When air pressure decreases, air cools down. More »

The atmosphere is divided into four layers because each layer has a distinctive temperature gradient. The four layers of the atmosphere are the troposphere, the stratosphere, the mesosphere and the thermosphere. Sometime... More »

In meteorology, temperature inversions occur in the layer of the atmosphere closest to the Earth's surface, known as the troposphere. Temperature inversions in the atmosphere occur when a cool layer of air close to the E... More »
