- Planets. A small number of meteorites are pieces of rock from the surfaces of other planets. …
- Moon. The most famous moon rocks are those collected by astronauts who walked on the Moon. …

What are main sources of meteoroids?
Most meteoroids come from the asteroid belt, having been perturbed by the gravitational influences of planets, but others are particles from comets, giving rise to meteor showers. Some meteoroids are fragments from bodies such as Mars or our moon, that have been thrown into space by an impact.
What are the three main sources of meteoroids quizlet?
Meteoroids can either be formed from asteroids or comets. They are the debris formed due to the collision of asteroids in space. Some meteoroids are formed when a comet breaks apart and releases dust clouds that move around the space.
What are the main sources of meteoroids quizlet?
What is the most likely source of meteoroids? Meteoroids come from asteroids that are broken apart by impacts with other asteroids.
What is the major source of meteor shower meteoroids?
Meteor showers occur when the earth in its orbit around the Sun passes through debris left over from the disintegration of comets. Although the earth's orbit around the Sun is almost circular, most comets travel in orbits that are highly elongated ellipses.
What causes a meteor?
A meteor is a streak of light in the sky caused by a meteoroid crashing through Earth's atmosphere. Meteoroids are lumps of rock or iron that orbit the sun. Most meteoroids are small fragments of rock created by asteroid collisions. Comets also create meteoroids as they orbit the sun and shed dust and debris.
What are the 3 types of meteoroids?
Types of Meteorites More than 60,000 meteorites have been found on Earth. Scientists have divided these meteorites into three main types: stony, iron, and stony-iron. Each of these types has many sub-groups.
What is the origin of asteroids?
Asteroids are leftovers from the formation of our solar system about 4.6 billion years ago. Early on, the birth of Jupiter prevented any planetary bodies from forming in the gap between Mars and Jupiter, causing the small objects that were there to collide with each other and fragment into the asteroids seen today.
What is the origin of iron meteorites quizlet?
Iron meteorites come from the cores of larger objects, most meteors come from comets, some stony meteorites resemble cooled lava, most meteorites come from asteroids, and stony meteorites come from the outer layers of larger objects.
Which of the following is source area for meteorites?
Most meteorites come from asteroids. You just studied 62 terms!
What is the origin of meteor showers?
Meteor showers occur when dust or particles from asteroids or comets enter Earth's atmosphere at very high speed. When they hit the atmosphere, meteors rub against air particles and create friction, heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars.
How are meteors created?
Meteors are flashes of light made when bits of space rock speed through our atmosphere and burst into flames. Meteors may be created by comets and asteroids but are not themselves comets and asteroids. A meteorite is a space rock that survives the trip through the atmosphere and lands on the surface of a planet.
What are 3 interesting facts about meteorites?
The oldest particles in a meteorite, calcium-aluminum-rich inclusions from carbonaceous chondrites, have been dated at 4.56 billion years old. Meteorites that originate from asteroids are all ~4.5 billion years old. Meteorites that originate from the Moon range in age from 4.5 to 2.9 billion years old.
Where do iron meteorites come from?
Iron meteorites are thought to be mostly derived from cores of differentiated planetesimals: a few likely formed from smaller metallic pools in the mantle or crust. Chondrites are divided into three major classes called enstatite, ordinary, and carbonaceous, which are subdivided into 13 groups.
Where are meteorites found?
About two thirds of meteorites found in the United States have been found in arid regions of California, Nevada, Arizona, New Mexico, Texas, and Kansas. 2200 meteorites have been found in Chile, mainly in the Atacama Desert.
What are the 3 types of asteroids?
The three broad composition classes of asteroids are C-, S-, and M-types.
- The C-type (chondrite) asteroids are most common. They probably consist of clay and silicate rocks, and are dark in appearance. …
- The S-types ("stony") are made up of silicate materials and nickel-iron.
- The M-types are metallic (nickel-iron).
What is the origin of the comets meteors and asteroids?
Meteors, Meteoroids, and Meteorites Meteorites are rocks from space that actually have landed on Earth's — or another planet's — surface. Meteor showers occur when Earth passes through the trail of dust and gas left by a comet along its elliptical orbit. The particles enter Earth's atmosphere and most burn up.
What are the three types of meteorites?
Scientists have divided these meteorites into three main types: stony, iron, and stony-iron. Each of these types has many sub-groups. Stony MeteoritesStony meteorites are made up of minerals that contain silicates—material made of silicon and oxygen. They also contain some metal—nickel and iron.
What is the source of the material that causes meteor showers?
Comets shed particles that appear as a dusty trail behind the “dirty snowball” of rock, ice, and gas that makes up the comet's nucleus. As the Earth passes through a comet's tail, the rocky debris collides with our atmosphere, creating the colorful streaks of a meteor shower.
What are the 3 main groups of asteroids?
Asteroid classification based on their chemical composition
- 1 – C-Type asteroids (carbonaceous) …
- 2 – S-Type asteroids (silicaceous) …
- 3 – M-Type asteroids (metallic)

What is the origin of comets?
It is thought that most comets originate in a vast cloud of ice and dust that surrounds the solar system. The Oort Cloud, as it is called, extends several thousand times farther from the Sun than Pluto, the outermost planet.
How are meteors caused?
Meteors are produced when particles of interstellar dust enter Earth's atmosphere at extremely high speeds (ranging from around 11km to 72km per second) causing them to burn up and leave a bright momentary streak across the sky. Earth encounters approximately 40,000 tonnes of extraterrestrial dust every year.
Where do comets asteroids and meteoroids come from?
Comets are small icy dirtballs that orbit the Sun; comets are made of ice and dust while asteroids are made of rock). A meteor is a space rock—or meteoroid—that enters Earth's atmosphere, as it – burns up upon entering Earth's atmosphere, it creating a streak of light in the sky (often called "shooting stars").
Where are two places comets can originate from quizlet?
Most comets originate from one of the two distant regions of the solar system: The kuiper belt and oort cloud.
What is the source of meteors we see during a meteor shower?
The rocky debris, consisting of mostly sand-size particles, continues in an elongated orbit around the Sun close to that of its parent comet. When the earth intersects this orbit in its annual trip, it can run into this debris, which burns up on entry into the earth's atmosphere, producing a visible shower of meteors.
How are the three related comets asteroids and meteors?
Answer and Explanation: Comets, asteroids, and meteors are alike in that they are small objects in space that formed from the same matter that created our solar system.
Where do most asteroids originate quizlet?
Where do asteroids originate in space? a. They originate in a belt between Mars and Jupiter.
What is an asteroids origin and orbit?
Asteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets. There are lots of asteroids in our solar system. Most of them are located in the main asteroid belt – a region between the orbits of Mars and Jupiter.
How meteorites are formed?
Meteoroids become meteors when they crash into Earth's atmosphere and the gases surrounding them briefly light up as “shooting stars.” While most meteors burn up and disintegrate in the atmosphere, many of these space rocks reach Earth's surface in the form of meteorites.
What is the origins of asteroids?
Asteroids are leftovers from the formation of our solar system about 4.6 billion years ago. Early on, the birth of Jupiter prevented any planetary bodies from forming in the gap between Mars and Jupiter, causing the small objects that were there to collide with each other and fragment into the asteroids seen today.
