As a meteoroid encounters the Earth's atmosphere frictional heating begins at an altitude of 100 to 120 km. What happens next depends on the speed, mass, and friability (tendency to break up) of the meteoroid. Micrometeoroids radiate heat so effectively that they survive unchanged to reach the surface as micrometeorites. Objects about the size of sugar grains burn up as meteors or "shooting stars". Friable meteoroids break up and are destroyed at altitudes of 80 to 90 km. Those which are tougher survive longer and produce fireballs as their surface is melted and eaten away at temperatures of several thousand degrees. Fireballs are often followed by meteorite falls.
A meteoroid entering Earths atmosphere producing a streak of light is known as a "Shooting Star" or sometimes a "Falling Star".
Just a sub note that if the meteoroid enters the atmosphere but does not hit the ground it is known as a meteor. If it hits the ground it is a meteoroid.
The streak of light from a meteoroid skimming through the Earth's atmosphere is called a Meteor. The light is produced by the ionization of gas as the meteroroid heats up with friction in the thin upper atmosphere.
It's called a "meteor", but friction isn't the primary cause of the heat. The cause of the heat, which often causes the meteoroid to explode or vaporize entirely, is caused even more by the heat of compression.
As you compress a gas, it heats up. (If you've ever filled a Scuba tank, you know that you have to have cold water running over the tank to remove the heat of compression; otherwise, the tank can fracture!) The more or the faster you heat it, the faster it heats up. A rock moving at 40,000 miles per hour or more is slamming into the atmosphere, but the air CANNOT MOVE OUT OF THE WAY fast enough. Air can't travel faster than the "speed of sound", which varies by altitude but isn't much higher than 800 MPH. So the column of air that's being compressed by the speeding rock, the superheating air can incinerate the rock, and thermal stresses can cause parts of the rock to heat up unevenly, causing it to fracture.
Oh, yeah, and there's a lot of heat of friction too, on top of the thermal compression.
"Meteor", "shooting star", or "falling star".

Those are called meteorites. The actual visual phenomenon (the thing you see) is also called a meteor, or a shooting star (but it's not really a star).
Friction is only part of the force that causes a meteor to heat up; compressive heating of the meteor compressing the air ahead of it is a more significant component.
The streak of light is usually called a shooting star.
The word used by astronomers is "meteor". Then, if it hits the ground, it's
called a meteorite.
A shooting star.
It is commonly called a shooting star
A meteoroid is a small metallic or rocky body. If it passes through the atmosphere causing it to burn up is called a meteor or shooting star. Any remnants that reach the earth are called meteorites.
A meteoroid is space debris that is made up of rock. A meteoroid that enters Earth's atmosphere and burns up is called a meteor. A meteorite is a meteor that survives the fall through Earth's atmosphere.
A stone entering the Earth's atmosphere is commonly referred to as a meteor. When it burns up and disintegrates due to atmospheric friction, it is called a meteoroid or shooting star. If it survives the journey and lands on Earth's surface, it is called a meteorite.
Meteor. And if it lands it is called a Meteorite.
Meteor - These fall into the Earth's atmosphere but burn up or vaporise before they touch the ground.Meteorite - These survive the fall through the Earth's atmosphere and crash onto the planet.
A meteoroid is a small metallic or rocky body. If it passes through the atmosphere causing it to burn up is called a meteor or shooting star. Any remnants that reach the earth are called meteorites.
The streak of light created by a meteoroid entering the Earth's atmosphere is called a meteor. A meteorite is the remains of a meteoroid that did not vaporize after entering the Earth's atmosphere.
A meteoroid is a small piece of space debris in the solar system. When a meteoroid enters the Earths atmosphere it becomes a meteor (shooting star).If the meteoroid survives the atmosphere and lands on the Earth, it becomes a meteorite.
The bright streak of light is the meteoroid burning up in the atmosphere due to friction from its extreme velocity. If the meteoroid completely burns up, it is called a meteor; if part of it makes it to the ground, it is called a meteorite.
A meteoroid is space debris that is made up of rock. A meteoroid that enters Earth's atmosphere and burns up is called a meteor. A meteorite is a meteor that survives the fall through Earth's atmosphere.
A meteoroid burning up on entering the atmosphere is commonly known as a shooting star.
A stone entering the Earth's atmosphere is commonly referred to as a meteor. When it burns up and disintegrates due to atmospheric friction, it is called a meteoroid or shooting star. If it survives the journey and lands on Earth's surface, it is called a meteorite.
When a meteoroid passes through Earth's atmosphere it's traveling very fast. The friction of the air makes gets the surface so hot it begins to burn or glow red hot. This fire is what you see as it goes through the atmosphere. If it burns up completely it's called a meteor.
A meteor.
MeteoriteThe glow surrounding a meteoroid is not caused by friction between the atmosphere and the meteoroid (as many people mistakenly believe), but rather due to the shock wave produced as a meteoroid slams into the Earth's atmosphere, rapidly compressing the air. This shock wave (properly called ram pressure) causes the exterior of the meteoroid to heat up and melt giving off a strong glow. Also, small amounts of gas surrounding the meteoroid are superheated as well, causing the bright tails seen behind meteors.
When a meteoroid enters the Earth's atmosphere, it is called a meteor. A meteor that passes through the atmosphere and strikes the ground is called a meteorite.
Sometimes it is called a "shooting star" but the stream of light is just the meteoroid burning up and parts of it break off.
