Sandstone is a (i) Sedimentary rock (ii) Aqueous rock (iii) Siliceous rock A. Only (i) B. Both (i) and (ii) C. Both (i) and (iii) D. All (i), (ii) and (iii)

[amp_mcq option1=”Only (i)” option2=”Both (i) and (ii)” option3=”Both (i) and (iii)” option4=”All (i), (ii) and (iii)” correct=”option3″]

The correct answer is: C. Both (i) and (iii)

Sandstone is a sedimentary rock that is composed of sand-sized grains of minerals, rock, or organic material. It is formed when sand is compacted and cemented together over time. Sandstone is a common type of rock, and it is found in many different parts of the world.

Sandstone is a sedimentary rock because it is formed from the accumulation of sediment. Sediment is material that is transported by water, wind, or ice and then deposited. Sandstone is typically formed from the deposition of sand, which is a type of sediment that is composed of small, loose grains of rock or mineral.

Sandstone is a siliceous rock because it is composed of silica. Silica is a type of mineral that is found in many different rocks, including sandstone. Silica is a very common element in the Earth’s crust, and it is the main component of quartz.

The other options are incorrect because:

• Option A is incorrect because sandstone is not only a sedimentary rock, but it is also a siliceous rock.
• Option B is incorrect because sandstone is not only an aqueous rock, but it is also a siliceous rock.
• Option D is incorrect because sandstone is not all three of the options listed.
