Question

How can an igneous rock turn into a sedimentary rock A through cementation pressure and erosion B through heat and erosion and pressure C erosion pressure and cementation D through erosion heat and pressure

Answer 1

The correct answer is **C: erosion, pressure, and cementation**.

Here's a brief explanation of the process:

1. **Erosion**: The igneous rock is broken down into smaller particles by weathering (physical or chemical processes) and is transported by water, wind, or ice.

2. **Deposition**: These particles are eventually deposited in layers in various environments (like rivers, lakes, or oceans).

3. **Compaction and Cementation**: Over time, the layers of sediment accumulate, and the weight of the overlying material exerts pressure on the lower layers, compacting them. Minerals precipitate from water that percolates through the sediments, binding the particles together (this is cementation).

Thus, through erosion, compaction, and cementation, igneous rocks can transform into sedimentary rocks.
