* Color: Rocks get their color from the minerals they contain. For example, quartz is often clear or white, while hematite is reddish-brown.
* Shape: Rocks can be smooth, angular, rounded, or even have complex shapes depending on how they formed and were weathered.
* Size: Rocks range from microscopic grains to massive boulders.
* Hardness: Rocks are rated on the Mohs Hardness Scale, with 1 being the softest (like talc) and 10 being the hardest (like diamond).
* Texture: Texture refers to the feel of a rock. It can be rough, smooth, gritty, or even have a crystalline texture.
These variations are what make rocks so fascinating! The differences in these characteristics help geologists classify rocks and understand their origins.
