Physical Geology
Extrusion is the geological process where molten rock, or magma, erupts onto the Earth's surface as lava. This process is crucial in forming new landforms and plays a vital role in the rock cycle by transitioning material from the interior of the Earth to its surface, where it can cool and solidify into igneous rock. The resulting volcanic activity can lead to various landforms, including mountains, plateaus, and islands, contributing to the dynamic nature of Earth's geology.
