What is the average speed at which a meteor hits the earth's atmosphere?

The minimum velocity of any meteorite falling into the Earth's gravity well would be the "escape velocity" of the Earth, about 25,000 miles per hour. Most will be going faster, sometimes MUCH faster. Radar tracking of Gemenid meteors a year or so ago showed that they were entering the atmosphere at 130,000 MPH!

∙ 14y agoit's called an asteroid when it's in space and a meter or meteorite once it enters earth's atmosphere; and they can travel between 40 and 50 thousand miles per hour! but then slows significantly once hitting our atmosphere, to about 12-15 thousand miles an hour

What causes a meteor to burn?
gases combined with the speed, plus the passing through earths atmosphere. Or to answer in a word........friction!
What speed must a space shuttle get to escape earth's orbit?
i think you mean atmosphere they normally go about 200,000 miles an hour when leaving earths atmosphere
How fast does a space shuttle reenter the earths atmosphere?
About thirty times the speed of sound, Mach 30 approx.
Why do meteors disintegrate?
They disintegrate when they come into Earth's atmosphere, as a result of the enormous energy that is liberated - this is the result of the meteor's fast speed, which makes it heat up.
What is the loud whizzing stones?
A loud whizzing stone may be referring to the sound a meteor makes when it falls to Earth. A meteor refers to space rocks that are able to break through the Earth's atmosphere and falls from the sky at a rapid speed.
A piece of rock or metal from space that enters the earths atmosphere at high speed and burns up?
Meteor

What causes a meteoroid to enter earths atmosphere?
The meteoroid heats up and sometimes breaks throught the atmosphere
Is a meteor a star such as part of the sun?
No, a meteor is a small piece of space rock that burns very brightly and with high temperature as it passes into our atmosphere at high speed.
What is the high speed stream of particles beating against the outer layer of earths atmosphere?
Solar wind
What is the average speed o f a meteor that is normal size?
About 94.000 mph (from 25000 to 160,000 mph)
What speed must a space shuttle get to escape earth's orbit?

How fast does a space shuttle reenter the earths atmosphere?
About thirty times the speed of sound, Mach 30 approx.
Can you touch a meteor?
No. A meteor is an object falling through the atmosphere, likely at a very high speed. Touching such a fast moving object can result in serious injury. A meteorite, which is a meteor that has stuck the ground, can samfely be touched. Contrary to popular belief, meteorites are not hot. The burn through the upper atmosphere is very brief, so little heat is transferred to the object.
Why do meteors have different colors such as red and blue?
It has to do with the chemical composition of the meteor and the speed in which the meteor is entering Earth's atmosphere. As the meteor plunges through the Earth's atmosphere, different temperatures will excite different chemicals within the meteorite all while the friction created from the meteor breaking though the atmosphere are stripping it of its' chemical layers. The temperature and the chemical composition that ignites will determine the color: sodium - orange/yellow iron - yellow magnesium - blue/green calcium - violet silicate - red
Why do meteors disintegrate?
They disintegrate when they come into Earth's atmosphere, as a result of the enormous energy that is liberated - this is the result of the meteor's fast speed, which makes it heat up.
9 Why does a meteor appear as a streak in the sky?
Because it's entry into the atmosphere at great speed causes enough friction to light it's fire.
