SSC CGL 2023 PYQ — Question 38

The correct answer is option 2 i.e. It is the most common sedimentary rock.

•  Granite is an igneous rock, not a sedimentary rock, so referring to it as "the most common sedimentary rock" is incorrect.
• The most common sedimentary rocks are sandstone, shale, and limestone, which are formed through sedimentary processes and have distinct characteristics from igneous rocks like granite.
• Formation of Sedimentary Rocks:
• Sedimentary Rock: These rocks form from the accumulation and compression of sediments such as sand, silt, clay, and organic material. They often form in layers and are the result of processes like weathering, erosion, and deposition.
• Types: Sedimentary rocks are categorized into clastic (formed from fragments of other rocks), chemical (formed from mineral precipitation), and organic (formed from the remains of living organisms).
