Coarse-grained texture in geology refers to the large, easily visible crystals in igneous rocks, indicating slow cooling of magma beneath the Earth's surface. This texture is typically found in intrusive rocks like granite, where the extended cooling period allows for the growth of large mineral grains.

Geology is the scientific study of the Earth, its materials, and the processes that shape its structure over time. It provides insights into Earth's history, natural resources, and the dynamics of natural hazards, making it essential for understanding both the planet's past and future.

Large visible crystals

Igneous rocks are formed from the solidification of molten magma or lava and are categorized into intrusive and extrusive types based on where they solidify. These rocks are fundamental to understanding Earth's geology as they provide insights into the planet's formation and the processes occurring beneath its surface.

Earth's surface

Intrusive rocks, also known as plutonic rocks, form from magma that cools and solidifies beneath the Earth's surface, leading to a coarse-grained texture due to the slow cooling process. These rocks are a fundamental component of the Earth's crust and provide critical insights into the planet's geological history and the processes occurring beneath its surface.
