Why don't meteors burn up when they first enter earth atmosphere?

Most do burn up entirely but the very largest ones do not completely burn up.


Most meteros burn up in the even though its the coldest layer?

Most meteors burn up in the mesosphere, which is indeed the coldest layer of Earth's atmosphere. As meteors enter this layer at high speeds, the intense friction generated by their interaction with air molecules causes them to heat up rapidly, leading to incandescence and disintegration. Despite the low temperatures, the density of air at this altitude is sufficient to create the friction needed for the meteor to burn up. Thus, the mesosphere effectively acts as a shield, protecting the Earth's surface from most meteoroids.


True or false most meteoroids burn up in the stratosphere?

False. Most meteoroids burn up in the mesosphere, which is located above the stratosphere. As they enter the Earth's atmosphere, they encounter increasing atmospheric pressure and friction, causing them to heat up and often disintegrate before reaching the surface. Only larger meteoroids may survive this process and reach the Earth's surface as meteorites.


Many more meteorites reach the surface of the moon because?

Many more meteorites reach the surface of the moon because it lacks an atmosphere to burn up incoming objects, unlike Earth. This means that the moon's surface retains more impact craters from these meteorite strikes compared to Earth.


Do meteors ever strike the sun?

Yes, meteors can strike the sun, but they most likely burn up in the sun's intense heat and radiation before reaching its surface. The sun's strong gravitational pull can also deflect or capture incoming meteors.
