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. 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. . Exploring gas pressure. The pressure of the atmosphere is not the same in all places – it varies with height.. High up a mountain the atmospheric pressure is much lower than at sea level.. In space there is no atmosphere and so there is no pressure.. Weather . – the condition of Earth’s atmosphere at a particular time and place.. Atmosphere. – the envelope of gases that surrounds the planet. The Main gases in the . Earth’s Atmosphere. ~ 75% Nitrogen. Earth’s . protective bubble. NASA accessed via Wikipedia . compared to the size of the Earth (10. 4. km), the atmosphere is a thin shell (120 km).. . Earth’s Atmosphere. http://www.gsfc.nasa.gov/gsfc/earth/pinatuboimages.htm. Weather vs. Climate. Weather is the condition of the atmosphere and surface at any given time.. C. limate is the average condition observed for longer time periods or long term expression of weather, typically . SUQ. Why is the atmosphere important for humans?. Which gas is the most abundant?. What is the other 1%. ?. Why is each significant?. Co2. Water vapor. Argon. Ozone. What happens to air pressure and temperature as one goes higher in the atmosphere?. Tuesday, September 20, 2011. Objectives:. 1. Explain the composition, structure, and properties of Earth’s Atmosphere.. 2. Explain the difference between Earth’s Early Atmosphere and the current Atmosphere.. GLY 4241 - Lecture 6 . Fall, . 2016. 2. Earth. Even in a high resolution image from space, the atmosphere is not visible. 3. Radiation. NASA graphic. 4. Chinese Smog. Haze over China. Increased desertification has added dust to China’s atmosphere. Properties of the Atmosphere Heat vs. Temperature Temperature – measure of how rapidly or slowly molecules move around. Higher the temperature = faster particle movement Heat - is the transfer of energy that occurs because of a difference in temperature between substances The thickness of our atmosphere is determined by two competing factors. The kinetic energy of the molecules . spreads molecules apart. Gravity . holds molecules near Earth. If it weren’t for gravity t. . 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. Layers of the Atmosphere.
