Minerals are deposited and accumulated in the stratas of which of the following rocks?

(a) sedimentary rocks

(b) metamorphic rocks

(c) igneous rocks

(d) none of the above

Answer:

(a) Sedimentary rocks ✅

Explanation:

Sedimentary rocks are formed by the accumulation, deposition, and compression of mineral particles over time. These rocks often contain important mineral deposits because minerals settle in layers (strata) due to natural processes like erosion, transportation, and deposition.

Points:

• Formation: Sedimentary rocks are formed by the deposition of sediments over millions of years.
• Common minerals: Coal, limestone, gypsum, and petroleum are found in these rocks.
• Layered structure: Minerals get trapped and accumulate in different layers (strata).

Sedimentary rocks play a crucial role in mineral deposits, as they trap and preserve valuable resources like coal, natural gas, and iron ore. ⛏️🌍
