Understanding Rock Formation

Rocks are classified into three main types: igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling and solidification of lava, which is molten rock. For instance, granite is a type of igneous rock that develops deep underground over a long period, while volcanic eruptions produce rocks rapidly from cooling lava. This process highlights the transformative nature of geology, showing how conditions such as temperature and pressure can lead to various rock formations.
