SOLAR SYSTEM

Detailed explanation-1: -About 86% of the meteorites are chondrites, which are named for the small, round particles they contain. These particles, or chondrules, are composed mostly of silicate minerals that appear to have been melted while they were free-floating objects in space.

Detailed explanation-2: -Where are meteorites found? Nearly all meteorites are found in deserts. (Yes, Antarctica is a desert because the annual precipitation rate is very low.) Deserts are places that accumulate meteorites over thousands of years and then nothing much happens to the meteorite.

Detailed explanation-3: -The surface of a meteorite is generally very smooth and featureless, but often has shallow depressions and deep cavities resembling clearly visible thumbprints in wet clay or Play-Doh. Most iron meteorites, like the example at right, have well-developed regmaglypts all over their surface.

Detailed explanation-4: -iron meteorites: which are almost completely made of metal. stony-iron meteorites: which have nearly equal amounts of metal and silicate crystals. stony meteorites: which mostly have silicate minerals.
