When it comes to rocks, they are typically divided into three main categories based on their formation processes. These categories are igneous rocks, sedimentary rocks, and metamorphic rocks.

Igneous rocks are formed from the cooling and solidification of magma or lava. Magma is molten rock beneath the Earth's surface, while lava is molten rock that has erupted onto the surface. Igneous rocks can be further classified into two types: intrusive igneous rocks, which form below the surface, and extrusive igneous rocks, which form on the surface.

Sedimentary rocks are formed from the accumulation and cementation of sediment particles. These particles can be derived from the weathering and erosion of pre-existing rocks, as well as the remains of plants and animals. Sedimentary rocks are often found in layers or strata, and they can contain fossils that provide valuable information about Earth's history.

Metamorphic rocks are rocks that have undergone changes in mineral composition and texture due to high temperatures, pressures, or chemically active fluids. These changes typically occur deep within the Earth's crust, where rocks are subjected to intense heat and pressure. Metamorphic rocks can form from both igneous and sedimentary rocks, and they often exhibit distinct foliated or non-foliated textures.

Understanding the different categories of rocks and their formation processes can provide valuable insights into the Earth's geological history and the processes that shape our planet. Whether you're a geology enthusiast or simply curious about the world around you, exploring the diverse world of rocks can be a fascinating journey.
