Rocks & Minerals (Including Rock Cycle)
WHAT ARE ROCKS & MINERALS?

A mineral is a natural solid with a characteristic crystal shape. Mineral crystals can form when hot water containing dissolved minerals cools down and forms a solid. Rocks on the other hand are made of mineral pieces mixed together. Rocks are made through the rock cycle! Read more about it below.

LET’S BREAK IT DOWN!

Minerals can form when water within Earth becomes saturated.

Minerals can form when water within Earth becomes saturated.

Minerals are solids that occur naturally and have a characteristic crystal shape. Hot water deep within Earth flows through cracks, where it can dissolve different substances. When hot water flows toward the surface, it cools and forms crystals. Hot water dissolves more minerals than cold water. When the water becomes saturated (can’t hold any more) with dissolved substances or cools, the water cannot hold onto all the dissolved minerals, and the minerals begin to crystallize on hard surfaces. Examples of minerals that form this way include gold, pyrite, and galena.
