Why do meteors burn only in the mesosphere but not thermosphere?
Q. According to my research, meteors burn in the mesosphere because of friction but I think there are also some molecules in the thermosphere, which means they will rub against the meteor. Please cite sources.

A. The thermosphere's temp is higher then the mesosphere however the thermosphere is very close to a vacuum so there is not enough friction to cause it to burn.

A. The asthenosphere (from Greek asthen s 'weak' + sphere) is the mechanically weak ductily-deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between 100 and 200 km (~ 62 and 124 miles) below the surface, but perhaps extending as deep as 400 km (~ 249 miles). Mesosphere, aka, mantle, is the interior of the Earth, similar to the other terrestrial planets, is chemically divided into layers. The mantle is a highly viscous layer between the crust and the outer core.

A. Here you go. The Troposphere The troposphere is where all weather takes place; it is the region of rising and falling packets of air. The air pressure at the top of the troposphere is only 10% of that at sea level (0.1 atmospheres). There is a thin buffer zone between the troposphere and the next layer called the tropopause. The Stratosphere and Ozone Layer Above the troposphere is the stratosphere, where air flow is mostly horizontal. The thin ozone layer in the upper stratosphere has a high concentration of ozone, a particularly reactive form of oxygen. This layer is primarily responsible for absorbing the ultraviolet radiation from the Sun. The formation of this layer is a delicate matter, since only when oxygen is produced in the… [cont.]

A. 1. The mesosphere starts just above the stratosphere and extends to 85 kilometers (53 miles) high. 2. Temperatures in the upper mesosphere fall as low as -100 C (-146 F or 173 K) , varying according to latitude and season.Within this layer, temperature decreases with increasing altitude. 3. The chemicals are in an excited state, as they absorb energy from the Sun. Millions of meteors burn up daily in the mesosphere as a result of collisions with the gas particles contained there, leading to a high concentration of iron and other metal atoms. 4.. The main dynamical features in this region are the atmospheric tides which are driven by momentum propagating upwards from the lower atmosphere and extending into the lower thermosphere.

Q. Why does the mesosphere decrease in temperature as the altitude rises?
Asked by Abby - Tue Oct 13 17:04:10 2009 - - 1 Answers - 0 Comments
A. The entire atmosphere is a temperature gradient starting at the surface of the Earth (+15 degrees C) and ending in space at roughly -273 degrees C. As soon as you start to ascend from surface, you lose temperature at 6.5 degrees Centigrade per 1000 meters! When you talk about Global Warming...please remember that after about 2000 meters, you are "warming" some pretty darn cold air...its all at Zero degrees ...all the time. Global Warming is actually simply an increased temperature gradient set up by very thin surface layer of air! Eventually the gradient will lessen as successive "layers" of the atmosphere become warmer, but it will take a very long time to substantially change that gradient.

A. The mesophere is the lower mantle of the earth. The mantle: The main bulk of the Earth, between the crust and core, ranging from depths of about 40 to 3480 kilometers. It is composed of dense mafic silicate and divided into concentric layer by phase changes that are caused by the increase in pressure with depth.The mantle is made up of dense, iron and magnesium rich (ultramafic) rock uch as dunite and peridotite. The uppermost part of the mantle is rigid and, along with the crust, form the 'plates' of plate tectonics. Hope this helps you out! : ) Also:

Asked by amy b - Tue Mar 30 20:55:44 2010 - - 1 Answers - 0 Comments
A. The trick here is not to confuse temperature with heat. The Thermosphere does have a relatively high temperature, but it is not "hot". Temperature is basically the measure of the average kinetic energy of an object or gas, while heat is that object ability to transmit that temperature. The atoms of the thermosphere have a high amount of kinetic energy due to absorption of solar radiation, but since the thermosphere is extremely thin, there is not much heat.

A. Go to this website and see if it helps: website highlight: Although the air in the mesosphere is relatively mixed, it is very thin, resulting in low atmospheric pressure. At this height, not only concentrations of ozone and water vapor are negligible, air in the mesosphere contains much less oxygen than in the troposphere.

In the thermosphere, the molecules of gas in the outer atmosphere are few and far between and so are free to move. Temperature is a measurement of the motion of the molecules, the more they move the higher the temperature. As you descend through the thermosphere, the air becomes denser and the molecules are closer together. The thermosphere also absorbs solar radiation such as xrays which warms the layer. This activity is at a minimum just above and down to the mesopause.
