Question

How do igneous rocks change into sedimentary rocks?

Answer 1

Igneous rocks change into sedimentary rocks through the process of weathering, erosion, and sedimentation. Here's how it works:1. Weathering: This is the process by which rocks are broken down into smaller pieces by natural processes like wind, rain, and ice. Igneous rocks are no exception. They can be weathered just like any other rock.2. Erosion: After the rocks have been weathered, the smaller pieces can be carried away by wind, water, or ice. This is called erosion.3. Sedimentation: Once the smaller pieces of igneous rock are carried away by erosion, they are deposited in a new location. This can be in a river bed, a lake, or even the ocean. Over time, the layers of sediment build up and become compacted. This is called sedimentation.4. Lithification: The final step in the process is lithification. This is when the sedimentary rock is cemented together and hardened into a solid rock. This process can take millions of years, but it results in a new type of rock that has formed from the old igneous rock.

On the surface, weathering and erosion break down the igneous rock into pebbles, sand, and mud, creating sediment, which accumulates in basins on the Earth's surface. As successive layers of sediment settle on top of one another, the sediment near the bottom is compressed, hardens, and forms sedimentary rock.

Answer 2

The igneous rocks are the basic material for the formation of the two other rocks types, the sedimentary and metamorphic rocks. These rocks are the first that form. They form from the magma that has cooled inside the crust, or by the lava flows on the surface. Over time, the weathering and erosion start to break them apart little by little, creating sediments from them. These sediments are the founding block for the formation of the sedimentary rocks. Once these sediments are exposed to certain temperatures and pressures they start to become compact again, which is made possible through the cementation process that keeps them together. As more and more sediments are merged together, the sedimentary rocks are formed, and they can come in multiple different types, sizes, shapes, as well as compositions, and structures.
