How rocks and minerals are formed?
The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which …

What are volcanic rocks and how are they formed?
Volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet. Volcanic rocks are fine-grained and are found on most terrestrial planetary bodies in our solar system.
What are igneous rocks and how are they formed?
Igneous rock is formed by the cooling and crystallization of magma or lava. A collection of igneous rocks. Igneous rock is formed by the cooling and crystallization of magma or lava. Their name comes from the Latin root “ignis”, which means “fire”.
