Through erosion, heat, and pressure, an igneous rock can turn into a sedimentary rock.
The correct answer is: through erosion, pressure, and cementation.
To understand how an igneous rock can transform into a sedimentary rock, we need to understand the rock cycle. The rock cycle describes the different processes that rocks undergo to form, change, and eventually become new rocks. In this case, we are looking at the transformation of an igneous rock into a sedimentary rock.
First, erosion plays a significant role. Erosion is the process by which weathering, such as wind, water, or ice, breaks down the igneous rock into smaller pieces or sediments. These sediments can be in the form of small pebbles, sand, or even clay.
Next, pressure comes into play. Over time, these sediments accumulate and get buried under layers of other sediments. The weight of these overlying sediments causes the sediments at the bottom to experience increased pressure.
Lastly, cementation occurs. Cementation is the process by which the sediments are compacted and bound together by minerals, often called cement, that act as a natural glue. This cementation process helps form sedimentary rocks.
So, when an igneous rock undergoes erosion, the resulting sediments can be transported by various agents like wind or water and then accumulate in a different location. As these sediments get buried under additional layers and experience increased pressure, they eventually become compacted and cemented together to form a sedimentary rock.
It's important to note that while heat and pressure can also be part of the rock cycle, they do not play a direct role in transforming an igneous rock into a sedimentary rock. Heat and pressure are typically associated with the formation of metamorphic rocks from existing rocks.
