Magma generation is the process by which molten rock, or magma, is formed beneath the Earth's surface due to the melting of pre-existing rock. This phenomenon occurs primarily in specific geological settings, such as subduction zones, where the subduction of one tectonic plate beneath another leads to the conditions necessary for melting. Understanding magma generation helps explain volcanic activity and the formation of igneous rocks, making it a crucial concept in studying Earth's geological processes.
