WebThe rock cycle is usually said to begin with a hot molten liquid rock called magma or lava. Magma forms under the Earth’s surface in the crust or mantle and erupts on Earth’s surface as lava. When magma or lava cools, it solidifies by crystallization, in which minerals grow within the magma or lava. The rock that results from this is an ... Web3.3 Crystallization of Magma. The minerals that make up igneous rocks crystallize at a range of different temperatures. This explains why a cooling magma can have some crystals within it and yet remain predominantly liquid. The sequence in which minerals crystallize from a magma is known as the. (Figure 3.3.1 and Figure 3.3.3).
