SOLAR SYSTEM

Detailed explanation-1: -back to “Some Meteorite Realities” If a meteoroid in space has a fracture (crack), then it will break from stress as it passes through Earth’s atmosphere. A meteorite that has been on Earth a long time might fracture, but not linearly. Linear fractures develop in igneous rocks as they cool.

Detailed explanation-2: -A meteorite fall, also called an observed fall, is a meteorite collected after its fall from outer space was observed by people or automated devices. Any other meteorite is called a “find". There are more than 1, 300 documented falls listed in widely used databases, most of which have specimens in modern collections.

Detailed explanation-3: -There are two main types of stony meteorite: chondrites (some of the oldest materials in the solar system) and achondrites (including meteorites from asteroids, Mars and the Moon). Both chondrites and achondrites have many subgroups based on their compositions, structures and the minerals they contain.

Detailed explanation-4: -Complete answer: Many meteorites are formed from a collision of asteroids that rotate around the sun between the tracks of Mars and Jupiter in the region called the asteroid belt. As asteroids break into each other, they produce loose debris-meteoroids.
