Igneous Rocks | Types, Classification, Properties, Formation
Igneous rocks are one of the three main types of rocks found on Earth, the other two being sedimentary and metamorphic rocks. These rocks form from the solidification and cooling of molten material, known as magma, which originates deep within the Earth's crust and occasionally even in the mantle. The term "igneous" comes from the Latin word "ignis," …
