FAQs on Meteors and Meteorites Video Lecture - Class 8

1. What is the difference between a meteor and a meteorite?
Ans. A meteor is a small celestial body that enters the Earth's atmosphere and burns up, creating a bright streak of light in the sky. On the other hand, a meteorite is a meteor that survives its passage through the atmosphere and lands on the Earth's surface.
2. How are meteors formed?
Ans. Meteors are formed when small rocky or metallic objects, known as meteoroids, collide with the Earth's atmosphere. The friction caused by their high speed through the atmosphere heats them up, causing them to burn and create a glowing trail of light.
3. What are the characteristics of meteorites?
Ans. Meteorites are typically composed of rock, metal, or a combination of both. They can vary in size, ranging from tiny specks to large boulders. Meteorites often have a dark crust on their exterior due to the intense heat generated during their atmospheric entry.
4. Where do most meteorites come from?
Ans. Most meteorites come from asteroids, which are rocky objects that orbit the Sun in the asteroid belt between Mars and Jupiter. Occasionally, meteorites can also originate from the Moon or Mars through impacts that eject rocks into space.
5. Are meteorites valuable?
Ans. Meteorites can have both scientific and monetary value. They provide researchers with valuable insights into the formation and evolution of the solar system. Some rare and unique meteorites, such as those containing extraterrestrial organic compounds, can also be highly sought after by collectors and may have a significant market value.
