GEOL 102 Lecture Notes - Lecture 13: Ultraviolet, Stratopause, Thermosphere
Document Summary
Why does the temperature increase with height in the stratosphere: contains ozone layer -> peak concentrations are at about 20-30 km, ozone absorbs ultraviolet radiation. The ozone then reemits this energy in the form of heat into the stratosphere, warming it up in the mid-upper parts of the layer. 97% of atmospheric ozone is in the stratosphere. Climate is what you expect, weather is what you get . Climate change usually refers to temperature change. Energy is defined as the ability to do work. Kinetic energy is the energy of motion. Temperature is the average kinetic energy of its constitute atoms and molecules (too hot-molecules move faster) Absolute temperature is proportional to the average kinetic energy of its constitute atoms and molecules. Heat is energy exchange from one object to another. Heat is an exchange of kinetic energy. Heat: energy exchanged from one object to another.
