Which layer of the atmosphere protects Earth's surface from being hit by the most meteoroids?
The mesosphere protects the earth from most meteoroids.
What layer in the atmosphere has most meteoroids break up?
Usually the troposphere.
Most common element in the earths atmosphere?
nitrogen is the most common element in the earths atmosphere
Why do some meteoroids that are traveling toward earth never hit earths suface?
All meteoroids that Earth encounters are moving very fast. When they strike the atmosphere their great speed superheats the air around them and they become meteors. The intense heat is enough to vaporize most meteors in a matter of seconds.
What would happen to most meteoroids when they enter earth's atmosphere?
They disintegrate into dust from the heat.
Why do meteoroids burn up as they approach earth but not the moon?
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.
Which layer of the atmosphere protct earth's surface from being hit by most meteoroids?
ozone layer
Are meteoroids and asteroids the same?
Asteroid: a large rock with its own orbit around the sun; most of them lie between the orbits of Mars and Jupiter. These rarely hit Earth, but it has happened. Meteor: a small piece of rock, ice, or dust that enters earth's atmosphere and quickly burns up as a result of high-speed friction with the gas molecules in our upper atmosphere, creating what is commonly known as a "shooting star." Meteoroid: a small particle of rock, ice, or dust floating around in space that hasn't entered our atmosphere yet. Meteorite: a small particle of rock that enters our atmosphere and has enough mass to survive the atmospheric entry process and actually impacts somewhere on Earth's surface.
Is most of the earths atmosphere covered with oxygen?
no
Most moisture enters the atmosphere by the process of....?
Evaporation
Most meteoroids that enter Earth's atmosphere are?
Particles the size of sand grains that come from many sources
What is most responsible for the pressure in the earths atmosphere?
The weight.
