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 Earths atmosphere changes con stantly as these gases are added and removed For example ani mals remove oxygen when they breathe in and add carbon dioxide when they breathe out Plants take in carbon dioxide and add oxygen to the atmosphere when they To distinguish normative properties from descriptive properties, we first need to distinguish2 normative predicates (such as 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. “Composition of Air and Air Pollution”. ***Rules***. 1.) Teacher will pick two students, one man and one woman.. 2.)

Conditions and composition of Venus’s atmosphere. Functions. Defn. : . Rational . F. unction. A function in the form: .  . The functions . p. and . q. are polynomials.. The domain of a rational function is the set of all real numbers except those values that make the denominator, q(x), equal to zero.. How does the atmosphere support life?. The atmosphere allows us to breathe. Many different types of organisms need oxygen to perform life processes. Plants require carbon dioxide to undergo photosynthesis. . 8. th. Grade Earth and Space Science. Class Notes. Atmosphere Basics. Combination of gases, dust, water droplets, and ice crystals. Surrounds the Earth. Extends from the Earth’s . . surface to outer space. 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 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 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.).
