1. Granite Rocks : Sima
- Incorrect. Granite rocks are typically associated with the continental crust, known as SIAL, which is rich in silicon and aluminum. Sima, on the other hand, refers to the oceanic crust, which is rich in silicon and magnesium.
2. Basaltic Rocks : SIAL
- Incorrect. Basaltic rocks are primarily associated with the oceanic crust, known as Sima. SIAL refers to the continental crust which is high in silicon and aluminum.
3. Mantle : Lithosphere and Aesthenosphere
- Correct. The mantle is divided into two sub-layers: the upper mantle, which is part of the lithosphere (along with the crust), and the lower mantle, which is known as the asthenosphere.
4. Core : Nife
- Correct. The core of the Earth is composed mainly of nickel (Ni) and iron (Fe), hence the term Nife. The core is divided into the inner and outer core.
Pairs 3 and 4 are correctly matched, making a total of two correctly matched pairs. Therefore, the correct answer is Option B: Only two pairs.
