What type of rock forms when igneous rock is weathered and eroded?

Sedimentary

For you future generation, it's sediment, trust me :) Sighned-Past you

The type of rock that forms when igneous rock is weathered and eroded is sedimentary rock. To understand why, let me explain the process:

1. Weathering: Over time, igneous rocks near or on the Earth's surface are exposed to various weathering agents like wind, water, and temperature changes. These agents break down the igneous rock into smaller particles or fragments.

2. Erosion: The fragments resulting from weathering are then transported by natural forces like water, wind, or ice. These forces move the rock particles from their original location and deposit them elsewhere.

3. Deposition: The transported rock particles settle and accumulate in new locations, such as bodies of water or on land. These accumulated particles are called sediment.

4. Lithification: Through the process of lithification, the sediment undergoes compaction and cementation. Compaction occurs when the weight of the overlying sediments compresses the lower layers, reducing the pore space between particles. Cementation happens when minerals, usually carried by groundwater, fill in the spaces between sediment particles and bind them together.

5. Sedimentary Rock Formation: Over time, with continued compaction and cementation, the sediment becomes solidified and transforms into sedimentary rock. This new rock consists of the compressed and cemented fragments of the original igneous rock, along with other types of sediment that may have accumulated during the process.

Therefore, the weathering and erosion of igneous rock leads to the formation of sedimentary rock.
