Question

through heat, erosion and pressure
through cementation, pressure and erosion
through erosion, heat and pressure
through erosion, pressure and cementation

Answer 1

An igneous rock can turn into a sedimentary rock through the processes of erosion, transportation, deposition, and then cementation. This means that the correct answer would be through erosion, pressure, and cementation, although the term "pressure" is less critical in the direct transformation from igneous to sedimentary rock compared to "cementation."

In summary, the steps are as follows:

1. Erosion: The igneous rock is broken down into smaller particles (sediments) through weathering and erosion.
2. Transportation: These sediments are transported by agents like water, wind, or ice.
3. Deposition: The sediments are deposited in layers.
4. Cementation: Over time, sediments are compacted and cemented together by minerals, forming sedimentary rock.

So, while none of the original options are entirely correct, the closest in meaning would be the fourth one: through erosion, pressure, and cementation.
