We often talk about climate change, melting glaciers, or strange landforms. But we rarely think about something that’s always ...

1. Igneous rocks Igneous rocks are formed from the cooling of molten rock. Molten rock is rock that has been heated to such a high temperature that it melts into a liquid.

While many rocks don’t burn, some of them do. It depends on what the rocks are made of – and that’s related to how they were formed. There are three main rock types: igneous, sedimentary and ...

Metamorphic rocks form from a previously existing rock, be it igneous, sedimentary or even an older metamorphic rock. Rocks turn metamorphic when they are subjected to very high heat and pressure.

While the molten and partially molten material that make igneous rocks tend to wipe away the traces of ancient organisms, the temperatures and pressures producing metamorphic rocks typically ...

Igneous and Metamorphic Rocks For instance, while igneous rocks form when the molten material from the planet’s core cools and sets as a single, solid mass, metamorphic rocks form when intense ...
