GENERAL KNOWLEDGE

Detailed explanation-1: -Meteoroids are objects in space that range in size from dust grains to small asteroids. Think of them as “space rocks.” When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors.

Detailed explanation-2: -A meteoroid is a chunk of rock or metal from space that falls through the atmosphere, or layer of gases, surrounding Earth. Most meteoroids burn up in the atmosphere. This creates a bright streak of light called a meteor. Meteors are also called shooting stars.

Detailed explanation-3: -Scientists have divided these meteorites into three main types: stony, iron, and stony-iron. Each of these types has many sub-groups. Stony MeteoritesStony meteorites are made up of minerals that contain silicates-material made of silicon and oxygen. They also contain some metal-nickel and iron.
