Igneous Rocks
Igneous rocks are formed from the cooling and solidification of molten rock, either magma beneath the Earth's surface or lava erupted from a volcano. They are fundamental to understanding the Earth's crust and geology.
Types of Igneous Rocks
Intrusive (Plutonic)
Formed beneath the Earth's surface where magma cools slowly, resulting in coarse-grained textures. Example: Granite.
Extrusive (Volcanic)
Formed on the Earth's surface when lava cools quickly, producing fine-grained or glassy textures. Example: Basalt.
Igneous rocks make up a significant portion of the Earth's crust and are often used in construction and decorative stonework due to their durability and aesthetic patterns.
