Detailed explanation-2: -After travelling through the atmosphere, meteorites that reach the Earth’s surface are typically small. Most meteorites reach the Earth’s surface in the form of dust or very small particles after passing through the atmosphere, which is why we do not normally see them.

Detailed explanation-3: -Some meteoroids are rocky, while others are metallic, or combinations of rock and metal. When meteoroids enter Earth’s atmosphere, or that of another planet, like Mars, at high speed and burn up, they’re called meteors.

Detailed explanation-4: -Meteorites are rocks from space that actually have landed on Earth’s-or another planet’s-surface.

Detailed explanation-5: -Meteorites have traditionally been divided into three broad categories: stony meteorites are rocks, mainly composed of silicate minerals; iron meteorites that are largely composed of metallic iron-nickel; and, stony-iron meteorites that contain large amounts of both metallic and rocky material.

Detailed explanation-6: -How do we get so many samples of meteorites? To date, there have been nearly 1, 100 recovered falls (meteorites seen to fall) and nearly 40, 000 finds (found, but not seen to fall). It is estimated that probably 500 meteorites reach the surface of the Earth each year, but less than 10 are recovered.
