The rock which is made up of molten magma is_______

Igneous rocks are formed from the cooling and solidification of molten magma or lava. When magma, which is molten rock beneath the Earth's surface, cools and solidifies, it forms intrusive igneous rocks (like granite), which occur deep within the Earth's crust. On the other hand, when lava erupts onto the surface and cools, it forms extrusive igneous rocks (like basalt).

These rocks are characterized by their mineral composition and texture, which are determined by the rate at which the magma or lava cools. Slow cooling results in larger crystals, while fast cooling results in smaller crystals.

In summary, igneous rocks are the only type of rocks that directly originate from molten magma, making them distinct from sedimentary rocks (formed from the accumulation of materials) and metamorphic rocks (formed by the transformation of existing rocks due to heat and pressure).
