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: Non-foliated metamorphic rock analysis (A)
These rocks lack layers. Quartzite, derived from sandstone, is a prime example. Thus, A corresponds to (IV).

Step 2: Foliated metamorphic rock analysis (B)
These rocks exhibit layers due to aligned minerals. Gneiss, a high-grade foliated rock, displays distinct banding. Thus, B corresponds to (III).

Step 3: Igneous rock analysis (C)
Igneous rocks originate from cooled magma or lava. Rhyolite is a volcanic (extrusive) igneous rock. Thus, C corresponds to (II).

Step 4: Sedimentary rock analysis (D)
Sedimentary rocks form from sediment accumulation. Dolomite (Dolostone) is a sedimentary carbonate rock. Thus, D corresponds to (I).

Conclusion: The correct match is A-IV, B-III, C-II, D-I.
