We can find asteroid in mesosphere. It is the outermost layer.
None. Asteroids exist outside the atmosphere.
The Earth's atmosphere is the layer that helps protect the planet from asteroids. When asteroids enter the Earth's atmosphere, friction causes them to heat up and break apart, reducing the impact of the asteroid on the Earth's surface.
The OZONE layer is in the upper atmosphere, known as the Stratosphere. NB Ozone is aan allotrope of oxygen . Atmospheric oxygen is two oxygen atoms combined together. Ozone is THREE atoms of oxygen combined together in a triangular arrangement.
The entire atmosphere will burn up small asteroids (meteors), but larger ones will strike the Earth. This is how the Caribbean Sea was created.
This layer is not specified. What is this layer?
The troposphere is the layer of the atmosphere closest to the Earth's surface and contains around 75% of the total mass of the atmosphere. This layer is where most weather phenomena occur and where we find the air we breathe.
Stratosphere
See "In what layer of the atmosphere do you find the ozone layer?"
The asteroid belt, is a "collection" of asteroids circling the Sun in between the orbits of Mars and Jupiter. A collection cannot have an atmosphere. A single asteroid does not have enough mass to "hold" on to an atmosphere.
Yes. Asteroids can enter earth's atmosphere. In such an event the asteroid will probably strike earth's surface.
The "ionosphere".
You can find the ozone layer in the lower stratosphere. It is because ozone find conditions worth creation there.
