It's simply dust and ice particles being heated - by friction, as the meteorite travels through the Earth's atmosphere.
becasue it encounters friction from the atmosphere
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
Global warming.
The streak of light across the sky caused when a space rock falls through the atmosphere and is heated to incandescence is a "meteor".
When a meteoroid enters Earth's atmosphere, it becomes a meteor. Friction with the atmosphere causes it to heat up and produce a bright streak of light in the sky. If any fragments survive the journey to the ground, they are called meteorites.
how do geologists think earths atmosphere is formed
The only difference of the twinkling caused by the distortion of light due to the earths atmosphere which is not present in a vacuum.
STRATOSPHERE
The term for an abnormally rapid rise in Earth's average temperature caused by excess carbon dioxide in the atmosphere is global warming.
When a meteoroid enters the earths atmosphere it is usually travelling very fast, fast enough to encounter great friction against the small amounts of gas at that height, so much so that is burns up under the heat generated. At that point it becomes very bright and visible to observers on earth, it is reffered to as a meteor or shooting star during the very breif burn phase.
Thermosphere, it is also the atmosphere with the highest temperatures.
Meteoritesis what we call stones that enter the earths atmosphere.
