What is the difference between magma and lava, and how does molten rock become igneous rock?
Magma is molten rock beneath the Earth's surface, while lava is its surface counterpart. When lava cools, it crystallizes to form igneous rock, showcasing a vital geological process. This transformation illustrates how molten rock transitions between different states and locations within the Earth.
Magma and lava are both forms of molten rock, but their key difference lies in their location. Magma is found beneath the Earth's surface, where it is kept under pressure and heat within the mantle and crust. In contrast, lava is magma that has reached the Earth's surface, typically following a volcanic eruption.
When lava solidifies after an eruption, it cools and crystallizes to form igneous rock. The cooling process can happen quickly when lava is exposed to air or water, resulting in extrusive igneous rocks like basalt. If magma cools slowly underground, it forms intrusive igneous rocks like granite. This transition highlights the cycling of materials in the Earth's geology, as the same material can change form based on its location and conditions.
