PPT-Heating the Earth’s Atmosphere

NWS There are several important heat transfer mechanisms that operate in the Earth system Conduction transfer of heat from molecule to molecule within a substance Heat transfer occurs from warmer to colder regions . Comfort is hard to define and is best understood as the absence of discomfort. Perhaps the most remarkable thing about radiant heat is what you won't notice. There are no forced air registers to see. No noise or dust from mechanical blowers. No hot air blowing on you. No hot air collecting at the ceiling, wasting energy. No cold floors to chill your feet. The mild warmth of a radiant floor is a subtle experience and always feels just right. 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 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. . Made by: Grace Taggart. Size. Moon- The Moon is 3,475km. Earth- The Earth is 12,756 km. Sun- The Sun is 1,392,684 km . What types of landforms are there?. Moon- The Moon is made out of hard rocks and there are many craters and mountains.. TOP SECRET PROFILE FOR SCIENTISTS ONLY . SIZE . The Earth size is 7,918 & 12,742. The Moon size is 3,476 & 2,159. LANDFORMS. The Earth landforms is mountains ,valleys, hills & ECT…. The Moon is the same as the earth & . 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 . 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.. transmitted. absorbed. reflected. 1. transmission. Radiation passes through atmosphere unimpeded.. Shortwave and longwave “windows” . 2. absorption. Energy is transferred to absorber; absorber emits energy. 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. . 7.5 Composition and Structure of the Atmosphere What is the composition of Earth’s Atmosphere? 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 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% Non-living synthesis of simple . organic. molecules. All of the elements found in organic compounds are thought to have existed on Earth and in the rest of the solar system when the Earth formed. . But .
