Types of Rocks in the Solar System

What are small pieces of rocks called?

1. Gravels

2. Pebbles

Answer:

Small pieces of rocks are named gravels or pebbles.

Small pieces of rocks, commonly known as gravels or pebbles, can come from various sources such as cosmic dust or meteorites. These small fragments can provide valuable insights into the early formation of the solar system. In addition to these small rock particles, there are different types of rocks found in the solar system, including sedimentary and metamorphic rocks.

Cosmic dust and meteorites play a significant role in the study of the solar system's history. Cosmic dust refers to the particles that originate from the solar system, while meteorites are pieces of debris that survive their journey through Earth's atmosphere and land on the planet's surface. These meteorites can contain vital information about the formation and evolution of the solar system.

Furthermore, there are rocks in the solar system that have extraterrestrial origins, such as fragments of meteorites that enter Earth's atmosphere. These rocks can provide valuable data about the early stages of the solar system's development.

On Earth, sedimentary rocks are formed by the deposition and cementation of materials, while metamorphic rocks are the result of high temperatures and pressures altering the form of existing rocks. These rock types are not as abundant on other planets in the solar system.
