PPT-Pressure and Temperature structure of the atmosphere:

Pressure gradient controlled by hydrostatic equilibrium pressure supports weight of gas above it and because it is gas density drops with decreasing pressure combination of effects leads to efolding drop in pressure over . 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. . 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.

Increased desertification has added dust to China’s atmosphere. La gamme de thé MORPHEE vise toute générations recherchant le sommeil paisible tant désiré et non procuré par tout types de médicaments. Essentiellement composé de feuille de morphine, ce thé vous assurera d’un rétablissement digne d’un voyage sur . 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% In fact, the atmosphere receives very low amount of heat energy from the sun as it receives most of its energy from the long wave terrestrial radiation.. Atmosphere receive energy from the sun and the earth in different ways. . 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. .
