PPT-Section 11.2 – Properties of the Atmosphere

Section 112 Properties of the Atmosphere 8 th Grade Earth and Space Science Class Notes Temperature Temperature measure of the average kinetic energy of the particles in a material Higher the temperature faster particle movement. Controlled atmosphere storage refers to the constant monitoring an d adjustment of the CO and O levels within gas tight stores or containers The gas mixture will constantly change due to metabolic activity of the respiring fruits and vegetables in t Key Terms. Atmosphere. – a thin envelope of gases that encircles the earth and other particles (aerosols). Weather. – the state of the atmosphere at a specific place and time. Meteorology. – the study of the atmosphere and the processes that cause weather. Essential Points. Heat, Temperature and Temperature Scales. The Electromagnetic Spectrum. Composition of the Atmosphere. Layers in the atmosphere are defined by temperature profiles. How pressure varies in the atmosphere. Sunrise . from space over the South China Sea. An astronaut would see something like this; clearly defined bands of color through the atmosphere as the sun rises. High-peaking cumulus clouds, topping out in anvil-head cirrus can be seen as black shadows against the sunlit horizon. The brightness of the colors in the atmosphere in this photograph is due to the amount of dust in the atmosphere. More dust is found in near the equator. There are various sources for such upper level dust. Many dust storms in Africa and ash clouds from major volcanic eruptions are two reasons. . Definition of the Atmosphere. . The layer of gases surrounding Earth; composed mainly of 78% nitrogen and 21% oxygen, and other gases (water vapor, dust, pollutants, etc.). Brainpop: . Earth’s atmosphere. The ocean/layer of gas that surrounds the Earth. It is composed of 78% Nitrogen and 21% Oxygen. The other 1 % is a mixture of other gasses. We depend on this balance of gas for our survival. When it is out of balance, we have problems.. Stars, solar systems form within giant molecular clouds. Requires . high density. , . dust, and low temperatures. to initiate gravitational . collapse. Most material is hydrogen and helium; only a few percent is other elements. NC Essential Standard:.
