Rocks (Mineralogy)

Rocks (in the field of Mineralogy) are objects (like pumice or limestone) that are non-living. Rocks contain material like minerals or magma that is cooled down.
According to researchers and self-observation, rocks take more time than a person’s life to finish growing. A rock is mostly just material, but it doesn’t have a shell.

Most volcanoes, like St. Helens would blow up, making ashes. This would cause disruption and distribution of hot substances, like lava. Over time, these materials become cooled down.
Imagine a candle. If the heat from the string is still burning, your wax would still melt. But if it is stopped, then the wax would become hard.
