Question

Match LIST-I with LIST-II
LIST-I (Type of Rock)
(A) Non-foliated metamorphic rock
(B) Foliated metamorphic rock
(C) Igneous rock
(D) Sedimentary rock
LIST-II (Characteristics/example)
(I) Dolomite
(II) Rhyolite
(III) Ornate Gneiss (Gneiss)
(IV) Quartzite

• A. A-II, B-IV, C-III, D-I
• B. A-I, B-III, C-IV, D-II
• C. A-IV, B-III, C-II, D-I
• D. A-IV, B-II, C-III, D-I

Hint:

Remember key examples for each rock type: - Igneous: Granite (intrusive), Basalt/Rhyolite (extrusive). - Sedimentary: Sandstone, Limestone, Shale, Dolomite. - Metamorphic: Marble (from limestone), Quartzite (from sandstone), Slate (from shale), Gneiss (foliated).

Answer 1

The Correct Option is C

Step 1: Analyze Non-foliated metamorphic rock (A)
These rocks lack a layered or banded appearance. Quartzite, formed from sandstone, is a classic example. Thus, A matches with (IV).

Step 2: Analyze Foliated metamorphic rock (B)
These rocks have a layered appearance due to the parallel alignment of minerals. Gneiss is a high-grade foliated rock with distinct banding. Thus, B matches with (III).

Step 3: Analyze Igneous rock (C)
Igneous rocks are formed from the cooling of magma or lava. Rhyolite is a volcanic (extrusive) igneous rock. Thus, C matches with (II).

Step 4: Analyze Sedimentary rock (D)
Sedimentary rocks are formed from the accumulation of sediments. Dolomite (or Dolostone) is a sedimentary carbonate rock. Thus, D matches with (I). Conclusion: The correct matching is A-IV, B-III, C-II, D-I.
