A common type of meteorite that contains chondrules. Chondrites come from asteroids that did not melt when formed and are designated as H, L, LL, E, or C depending on chemical compositions. The H, L, and LL types are called ordinary chondrites. The L chondrites are composed of silicate minerals (mostly olivine and pyroxene, but feldspar as well), metallic nickel-iron, and iron sulfide (called troilite). Most L chondrites are severely shocked-damaged, probably by a large impact on the asteroid in which they formed. The C (or carbonaceous) chondrites are the most primitive meteorites. They contain water-bearing minerals and carbon compounds including a variety of organic molecules such as amino acids.

The remains of extraterrestial particles that are found on Earth's surface is called?
Meteorites. There are many different kinds: chondrites, achondrites. But simply put extraterrestril particles are meteorites.
What ended the Cretaceous Period?
The mass extinction of the dinosaurs occured at the end of the Cretaceous Period. There are many theories as to why this happened. Some say a volcanic eruption caused it or a falling meteorite.
How do scientists map out the earths interior?
FIRST OFF ID0414442662 THAT WAS A DUMB ANSWERKnowledge of the Earth's interior is based on the reactions of seismic waves from earthquakes to the density and state of materials that they encounter. Seismic waves travel at differing speeds through different materials (and also, at different speeds through material of different states, i.e., liquid or solid). Because we know the size of the Earth, by measuring how long it takes to pick up on seismic activity on opposite sides of the Earth, we can gauge about how much of the Earth is solid, liquid, made of a certain material, etc.Some of it, also, is based on our current understanding of how the Earth formed - mainly, that as our planet formed and cooled, the heavier materials such as metal sunk to the center.Rock that is torn off and expelled by volcanism is studied as another indicator of what lies below the surface. Another clue lies in meteorites that have landed on Earth known as Chondrites. These can indicate the material from which planets are formed. The How_do_scientists_know_about_the_Earth's_interiorof Earth's magnetic field and gravitational properties also indicate or strongly infer what lies deep in Earth's interior.Knowledge of the shallower (but otherwise difficult to access) oceanic crust and mantle has been gained due to a process known as obduction where oceanic crust is forced over continental crust. These rocks are known as Ophiolites and give Geologists direct access to the rocks in question

What is a name of a meteorite?
Meteorites are named according to their composition as ordinary chondrites, carbonaceous chondrites, achondrites, iron meteorites, and stony-irons.
What are the two types of stony meteorites?
Chondrites and Achondrites
What are the sub types of stony meteorites?
Chondrites and Achondrites.
What has the author Derek W G Sears written?
Derek W. G. Sears has written: 'The origin of chondrules and chondrites' -- subject(s): Chondrites (Meteorites), Chondrules
What has the author A Bischoff written?
A. Bischoff has written: 'Catalog of Al-rich chondrules, inclusions, and fragments in ordinary chondrites' -- subject(s): Catalogs and collections, Chondrites (Meteorites), Chondrules
Do Carbonaceous chondrites contain simple amino acids?
Yes
What is Equilibrated chondrites?
Chondrites are stony meteorites that have not been modified due to melting or differentiation of the parent body. In other words, these rocks are roughly indicative of what was formed over 4.5 billion years ago at the formation of the solar system. Equilibrated chondrites refers to those which have become essentially homogeneous in mineral composition due to thermal metamorphism. Small chondrules are often no longer recognizable.
What is true of the amino acids that might have been delivered to Earth within carbonaceous chondrites?
The proportion of the amino acids are similar to those produced in the Miller-Urey experiment.
What are 3 main types of meteoroids?
stony - rocksmetallic - a nickel iron alloycarbonaceous chondrites - contain large amounts of organic chemicals

Meteorites. There are many different kinds: chondrites, achondrites. But simply put extraterrestril particles are meteorites.
What is the mean density of a meteor?
They're probably all slightly different, but the various classes of meteorites will have different densities. Most of them are stony meteorites, but a few are metallic, and some are chondrites.
What are meteorite made?
There are three basic categories of meteorites. The easiest ones to recognize were the iron or nickel-iron meteorites; most of the others look pretty much like rocks, but before people knew how to smelt iron, nickel-iron meteorites really stood out. Another type is the stony meteorites, subdivided into chondrites and achondrites... as you might guess from the name, they're made of rock. The chondrites contain small round particles called chondrules, the achondrites don't. Finally, there are the stony-iron meteorites, which are partly rock and partly metal.
