* Rocks: These are the most common example. Rocks are made of minerals and can be formed through various geological processes like volcanic eruptions, erosion, and the cooling of magma. Examples include granite, basalt, limestone, and sandstone.
* Minerals: These are naturally occurring, solid, inorganic substances with a specific chemical composition and crystal structure. Examples include quartz, diamond, gold, and salt.
* Ice: This is a solid form of water and forms naturally in cold environments.
* Sand: This is made of tiny rock fragments and mineral grains.
* Clay: This is a fine-grained earth material formed from the weathering of rocks.
* Meteorites: These are fragments of asteroids or comets that have fallen to Earth.
