Detailed explanation-1: -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. When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.
Detailed explanation-2: -Meteorite is the part of meteor which reaches the earth’s surface.
Detailed explanation-3: -When a meteoroid enters Earth’s upper atmosphere, it heats up due to friction from the air. The heat causes gases around the meteoroid to glow brightly, and a meteor appears.
Detailed explanation-4: -When the meteors enter the earth’s atmosphere they burn due to the friction caused by the earth’s gravity and a streak of light is seen. This is referred to as shooting star.
Detailed explanation-5: -Meteors are produced when particles of interstellar dust enter Earth’s atmosphere at extremely high speeds (ranging from around 11km to 72km per second) causing them to burn up and leave a bright momentary streak across the sky. Earth encounters approximately 40, 000 tonnes of extraterrestrial dust every year.
