To understand how an igneous rock can turn into a sedimentary rock, it's important to understand the process involved. Sedimentary rocks are formed through a process called lithification, which involves the transformation of loose sediment into a solid rock.
Here's a step-by-step explanation of how an igneous rock can become a sedimentary rock:
1. Erosion: First, weathering and erosion break down the igneous rock. This can happen through various processes such as wind, water, or ice. The igneous rock is gradually broken into smaller pieces, forming various sediment particles.
2. Transport: The eroded sediment particles are transported away from their original location by agents like water, wind, or gravity. They can be carried away and deposited in a different environment.
3. Deposition: As the sediment particles are transported, they eventually settle and accumulate in a new location. This is called deposition. The particles can settle in bodies of water like rivers, lakes, or oceans and form layers of sediment.
4. Compaction: Over time, as more and more sediment layers accumulate, the weight of the upper layers compresses the lower layers. The pressure from the weight of the overlying sediments squeezes out air and water, causing the sediment particles to become more compacted.
5. Cementation: The compacted sediment particles are further cemented together by minerals that act as a binding agent. This process is known as cementation. Minerals dissolved in water seep through the pores between the sediment grains and harden, binding the particles together and forming a solid sedimentary rock.
So, the correct answer is Option 1: through erosion, heat, and pressure. The heat and pressure involved in the process mostly occur during the compaction and cementation stages, which help transform the loose sediment into a solid sedimentary rock.
