What's the difference between chondrite and meteorite?
Chondrite
Definition:
(n.) A meteoric stone characterized by the presence of chondrules.
Example Sentences:

(3) Further theoretical and experimental studies support the view that hydrogen cyanide polymerization along these lines is a universal process that accounts not only for the past formation of primitive proteins on Earth, but also for the yellow-brown-orange colors of Jupiter today and for the presence of water-soluble compounds hydrolyzable to chi-amino acids in materials obtained from environments as diverse as the moon, carbonaceous chondrites and the reaction chambers used to simulate organic synthesis in planetary atmospheres.
(4) This fraction was also present in extracts from the Murray and Mighei CM2 chondrites.
(5) The latter results belong with a program of interdisciplinary research applications of the new microprobe, which include studies of e.g., the monolayer lateral distribution of intercalant in SbCl5 intercalated graphite and of silicate minerals and iron distribution in sections of chondrules and their rims (components of chondrites, a class of stony meteorites).
(6) Since the initial find in the Murchison meteorite (a type II carbonaceous chondrite) of both protein and nonprotein amino acids with nearly equal abundances of D and L isomers, further studies have been carried out.
(7) A carbonaceous chondrite from the Antarctic, referred to as the Allan Hills meteorite 77306, appears to be free from terrestrial organic contamination.

(9) The distribution patterns of REE in the NBS materials relative to chondritic meteorites resemble the patterns for geological materials.
(10) Samples of the Murchison CM2 chondrite were extracted with chloroform-methanol, and the chloroform-soluble material was separated by two-dimensional thin layer chromatography.
(11) These objects contained relatively small amounts of water and carbon in a form similar to that found in carbonaceous chondrites.
(12) The recent development of sophisticated analytical techniques and availability of carbonaceous chondrites with a minimum of terrestrial contamination has resulted in the identification of amino acids which provide strong evidence for a natural extraterrestrial chemical synthesis.
(13) Investigations of the Murray meteorite (a type II carbonaceous chondrite) has produced similar results, but studies of the Orgueil meteorite (a type I carbonaceous chondrite) show only a limited suite of amino acids, some of which appear to be indigenous while others appear to be terrestrial contaminanats.
(14) A GC-MS examination of the heterocylics showed resemblance with those found in some carbonaceous chondrites.
(15) The team collected fragments of chondrite that matched other chunks of the meteorite.
(16) Because of the fragility of the laryngotracheal tree in children, and the serious consequences on function of any chondritic lesion or even mucosal edema, overall endoscopic treatments combined with prosthesis insertion are preferred to any surgical procedure.
(17) The role and relative contributions of different forms of energy to the synthesis of amino acids and other organic compounds on the primitive earth, in the parent bodies or carbonaceous chondrites, and in the solar nebula are examined.
Meteorite
Definition:
(n.) A mass of stone or iron which has fallen to the earth from space; an aerolite.
Example Sentences:
(1) The toll was slight because the 20-metre-wide meteorite exploded so high, more than 20km above the ground.
(2) We’ve gathered a few creative intergalactic lesson plans below – including edible meteorites and studying real lunar rocks.
(3) "It was rather easy to find fragments in the first days after the meteorite fell, because the chunks left holes in the snow," Grokhovsky told the Guardian.
(4) The amino acid composition and the pyrolyzable organic content of the Antarctic Allan Hills meteorite (ALHA 77306.9 and ALHA 77306.17) was examined.
(5) Short of sending a spacecraft or astronaut to the red planet to haul back rocks, Martian meteorites are the next best thing for scientists seeking to better understand how Earth's neighbour transformed from a tropical environment to a frigid desert.
(6) Having an accurate measurement of the Martian atmosphere also clears up some confusion over the origin of a group of meteorites on Earth, that were assumed to have originated from Mars based on measurements of trapped gases within them, but their identity could not be confirmed without the hard data provided by these results.
(7) A sample of the Murchison meteorite was extracted with D2O and in addition of 'free' amino acids, showing no deuterium incorporation, some amino acids showed the presence of deuterium suggesting either a 'precursor(s)' or hydrogen-deuterium exchange which require(s) formation of carbon-hydrogen bonds.
(8) First, grab an apron and get baking; the meteorite recipes can be found here .
(9) It was that moment when me and my colleagues from Ural Federal University's nanotech centre determined the meteorite's origin and the substance of the chunks which were collected not far from the hole in the ice," Grokhovsky said.
(10) Or it can be “to solve some mystery”, such as his trips to Guatemala and Belize, to uncover the fate of the Mayan civilisation, or Siberia, to learn about the Tunguska meteorite, thought to have created a blast as powerful as 1,000 Hiroshimas in 1908.
(11) "It is very hard to overestimate the importance of the meteorite's recovery from the lake.
(12) Meteorites, The Universe, Road to the Stars, Planet of Tempests, The Moon, et al.
(13) Researchers performed a battery of tests on the meteorite and, based on its chemical signature, confirmed it was blasted to Earth from Mars.
(14) "Unless he takes a tumble or is hit by a falling meteorite."
(15) "It's yet another piece of evidence which makes it more likely that life came to Earth on a Martian meteorite, rather than starting on this planet."
(16) It relies upon the expected El Nino which is currently 70~90% likely A major volcanic eruption or a giant meteorite could change this, otherwise 2015 is the one to watch.
(17) 1.1m page views 10) Meteorite slams into central Russia injuring 1,100 – live Friday 15 February 2013 "I was driving to work, it was quite dark, but it suddenly became as bright as if it was day.
(18) Most space rocks that fall to Earth as meteorites come from the asteroid belt, but a number can be traced to the moon and Mars.
(19) For example, it is estimated that a major meteorite impact, such as the one that caused the extinction of the dinosaurs 65m years ago, occurs on average every 100m years.
(20) Cut the edible meteorites in half so students can describe what they are like inside, but make sure they use technical vocabulary not culinary terms.
