"where the oxygen level increases then combustion takes place"
MESOSPHERE
The Earth has an atmosphere around it.The Thermosphere is the top-most layer of the atmosphere.The troposphere is the lowest part of the atmosphere.Unlike Earth,the Moon has no atmosphere.That's why meteoroids don't burn up before they hit the surface.Even though the Earth's atmosphere is immense,sometimes meteoroids get through the atmosphere.
Meteors.
Meteoroids are more likely to strike Mercury because its proximity to the sun results in a denser population of meteoroids in its vicinity. Additionally, Mercury's lack of a substantial atmosphere means there is no protective layer to burn up meteoroids before they reach the surface. Earth's atmosphere, on the other hand, acts as a shield, causing most meteoroids to burn up before they reach the surface.
True. The vast majority of meteoroids burn up in the atmosphere, and reach the ground only as dust, after drifting around in the atmosphere for some time. (The stuff you wipe off the top of the TV set? Some of it is probably meteor dust.)
That's a description of meteoroids.
Because they are going at very high speeds. Things cannot burn in space, because there is no oxegen.
Most meteoroids break up in the mesosphere, which is the layer of the atmosphere located between the stratosphere and the thermosphere. This is where most meteoroids encounter enough friction and pressure from the atmosphere to burn up and disintegrate before reaching the Earth's surface.
Both meteoroid's and comets are made out of rock and burn up when getting into earths atmosphere.
The term that specifically describes small chunks of rocks and debris in space that burn up in Earth's atmosphere is "meteoroids." When these meteoroids enter the atmosphere and create a bright streak of light, they are referred to as "meteors." If they survive their passage through the atmosphere and land on Earth, they are then called "meteorites."
The mesosphere is the atmospheric layer that protects the Earth from meteoroids. As meteoroids enter the Earth's atmosphere, they burn up in this layer due to friction with air molecules, preventing them from reaching the surface.
Meteoroids burn up in the Mesosphere. Even though the Mesosphere is the coldest layer, the meteoroids burn up from getting too cold. Meteoroids are also more commonly known as "shooting stars".
