How did meteorites come about and how did they form?

Meteorites are unburned materials that fall to the surface of the Earth or other planets after entering the gravitational range of the Earth or other planets. Meteorites can be stony, iron, or a mixture of rocky iron, as well as a mixture of ice and solid debris.

in the solar system. Inside and at the edges, there are countless solid materials of different sizes, some of which come from leftover material from the formation of the solar system, some of which are fragments formed by the formation of the solar system that did not aggregate to form large planets, or some smaller planetary blanks that collide with each other. The vast majority of meteorites are concentrated on Mars and Jupiter.

The asteroid belt between orbits.

Inside. These objects usually follow a certain orbit within the solar system, but their trajectories can change if they collide with each other or are disturbed by the gravitational pull of massive objects such as planets. If they move near larger planets and are gravitationally pulled by them, they can fall towards them, and when they fall to the surface of the planet, they become meteorites.

Meteorite falls.

When meteorites fly at high altitudes, the surface temperature reaches several thousand degrees. At such high temperatures, the surface of the meteorite melts into liquid. Later, due to the blockage of the dense atmosphere in the lower layers, his speed became slower and slower, and the molten surface cooled down, forming a thin crust called "molten crust".

The molten shell is very thin, generally around 1 mm, and the color is black or brown.

In the process of cooling the molten shell, the traces of air flowing on the surface of the meteorite are also retained, which are called "gas marks". The air mark looks much like a finger print pressed on the dough. Molten crusts and air marks are the main features of the surface of meteorites.

The meteorite was originally an asteroid, which fell into the Earth's atmosphere after a collision, and it was a meteorite that fell to the ground after experiencing ** burning.

If you see a rock or iron with such a molten shell or air mark on its surface, you can immediately conclude that it is a meteorite. However, some meteorites that fall down are older, due to long-term wind, sun and rain, the molten shell falls off, and the air mark is not easy to identify, but that doesn't matter, there are other ways to identify it.

Lunar meteorites and Martian meteorites.

Broadcast. Lunar meteorites can be divided into two categories: volcanic rocks and sedimentary rocks, and lunar basalt is one of the main rocks that make up the moon, with colors such as black, white, dark purple, purple-red, green, dark green (commonly known as black treasure green), gray-green, yellow, brown-yellow, mixed colors, etc. Speckle structure and almond structure with biotite. Common sulfides found in lunar meteorites are meteorite iron, pyrite, chalcopyrite, chalcopyrite, sulfur nickelite, and unknown minerals.

The transparent molten crust on the surface of the lunar meteorite, which is a volcanic rock, is formed by the melting of the transparent material in the lunar rock at high temperature. Other melting phenomena such as molten crusts, melt streaks, flow lines, grooves, foil pits, and edges and corners formed by directional falls are evident.

Meteorites are cosmic meteors or fragments that have escaped from their original tunnels outside the Earth. Most of the meteorites come from the asteroid belt between Mars and Jupiter, and a small number come from the Moon and Mars.

An asteroid, comet, or rock from space, when it is close to the Earth, is captured by the Earth's gravitational pull and crashes into the atmosphere, eventually landing on the Earth.

A meteorite is a small planet or stone in space other than a planet, which is hit by the gravitational pull of the earth.

2. In the process of cooling the molten shell, the traces of air flow blowing on the surface of the meteorite are also retained, which is called "air seal". The air mark looks much like a finger print pressed on the dough. Molten crusts and air marks are the main features of the surface of meteorites.
