PPT-Chapter 2: Atmosphere: Origin, Composition, and Structure

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.

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. 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 . . General Characteristics. Composition- Gases, water vapour and dust particles. Structure: Layered structure, variation with altitude, latitude and seasons; Importance and characteristics of each layer.. “…sparked by just the right combination of physical events & chemical processes…”.

Increased desertification has added dust to China’s atmosphere. . General Characteristics. Composition- Gases, water vapour and dust particles.

SC.6.E.7.9, LA.6.2.2.3 Composition of Earth’s Atmosphere The atmosphere is the protective covering of Earth. It keeps Earth warm and protects it from 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 (they are trivially simple, but they do give some interesting results if you ask the right questions). The Physical Principal – . Conservation of Mass. Bulk Silicate Earth . (the hypothetical homogeneous composition of the solid silicate Earth after core formation, but before any other differentiation process). These guidance documents are of an explanatory and illustrative nature. Legislation takes precedence over the content of these documents and should always be consulted..  . What are Rules of Origin?.
