PPT-Properties of the 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. 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. 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. and the Impact on Living Things. Earth’s Atmosphere. The gases that surround Earth (and other planets) make up the atmosphere. These gases are like an envelope that protects us from the radiation that is caused by the sun’s . Weather. Whether the weather be fine,. Or whether the weather be not,. Whether the weather be cold,. Or whether the weather be hot,. We'll whether the weather. Whatever the weather. Whether we like it or not. Sulfur Compounds . and Their . Chemistry . for Venus and the Interstellar Medium. David . E. . Woon. FA08. Overview of Talk.  Sulfur (and Chlorine) in Venus Atmospheric Chemistry.  . Conditions and composition of Venus’s atmosphere. Section 11.2 – 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 Atmosphere Essential Question: How are we changing our atmosphere? Learning Goals: Be able to identify the layers of the atmosphere. Describe what molecules make up the atmosphere. Atmosphere Atmosphere ATMOSPHERE Composition of the Atmosphere The atmosphere is comprised of a variety of gases: Major Constituents (99%): Nitrogen (N): 78% Oxygen (O 2 ): 21% Trace Constituents: Other: 1% Elisabeth Andrews. CATCOS Aerosol Workshop, June 2016. What’s an Aerosol. ?. Definition: . Particle or liquid suspended in a gas.. Examples of atmospheric aerosols:. Dust. Combustion aerosol (forest fires, vehicles…). . 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. 3. Its structure, composition and dynamics. In last week’s lecture, we focussed on how weather is generated.. The key ingredients are energy and gradients.. Last Week’s Lecture. Incoming energy from the Sun is balanced with outgoing radiative cooling of the Earth, resulting in an equilibrium temperature of about 15 °C. .
