When meteoroids survive their journey through Earth's atmosphere and land on the ground, they are called meteorites. These space rocks provide valuable information about the composition of our solar system.

Meteorites
Meteorites are meteoroids that survive their journey through Earth's atmosphere and land on the ground. Here's a detailed explanation:

Definition:
- Meteorites are fragments of asteroids or comets that survive the intense heat of entering Earth's atmosphere and make it to the ground.

Types of Meteorites:
- Iron Meteorites: These are composed mostly of iron-nickel alloys.
- Stony Meteorites: These are made primarily of silicate minerals.
- Stony-Iron Meteorites: These contain a combination of both iron-nickel alloys and silicate minerals.

Composition:
- Meteorites can contain valuable scientific information about the early solar system as they are remnants of the building blocks that formed planets.

Impact Craters:
- When large meteorites strike the Earth, they can create impact craters, which are circular depressions in the ground.

Research Importance:
- Scientists study meteorites to learn more about the formation and evolution of the solar system.
- They can provide insights into the conditions present in the early solar system and the processes that led to the formation of planets.
Meteorites are fascinating objects that hold valuable clues about the history of our solar system. By studying them, scientists can gain a better understanding of the processes that have shaped our planet and the universe.
