PPT-Atmosphere (air)

Bacteria have transformed you into nitrogen gas and you are now part of the atmosphere Forest Fire The wood you were within is burnt and you have been released into the atmosphere How did you arrive. 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.. And its effects on our planet Earth. What is the Atmosphere. ?. The . envelope of gases surrounding the earth or another planet. .. Earth’s atmosphere consists of 5 major layers. Troposphere. Stratosphere. 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:. Compare the composition, properties, and structure of Earth’s atmosphere to include: mixtures of gases and differences in temperatures and pressure within layers.. There are . E4.p2X-A,F, I. Characteristics of the Atmosphere. Composition of the Atmosphere. Atmosphere. -mixture of gases around the Earth. 78% Nitrogen-(released from decay/eruptions). 21% Oxygen. 1% Other- (Carbon Dioxide, Argon). 7. th. Grade . Choose Your Category!.

Two major gases are . Nitrogen. (70%) and . Oxygen. (20%). Most other gases are found in varying amounts. Carbon dioxide . is found in increasing amounts because of . human activities. CO. 2. raises the temperatures in the atmosphere because of a . 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.. The Atmosphere. The . atmosphere. is the layer of gases that surrounds the Earth.. It is made up of several different molecules, such as nitrogen gas, oxygen gas, and carbon dioxide.. The atmosphere is vital to respiration, as it contains both oxygen and carbon dioxide..  . Activity: Aim: To show that Air occupies space..   . Materials required:. A piece of paper, a bowl, water, a glass..  . Procedure: . (. i. ). . Let us crumple a sheet of paper. (ii) Let us stuff the paper ball inside a glass. (iii) Let us invert the glass and push it into a bowl of water..
