Magmas are molten rocks that can be found beneath the Earth's crust. These rocks can be made up of a variety of minerals such as silica, iron, and magnesium. There are several synonyms for the term magmas, such as lava, volcanic rock, and molten rock. Lava refers to the magmas that have been released from the Earth's surface while volcanic rock denotes the hardened form of these magmas. Molten rock, on the other hand, simply refers to the melted state of any type of rock. Other variations of the term magmas include magma chamber, volcanic ash, and magma flows. These terms are all related to the study of volcanoes and can provide a better understanding of the geologic processes happening beneath our feet.
