Which is matched correctly for Weathering of Earth materials.

1. Exfoliation domes - Unloading

2. Tors - Thermal expansion

3. Geomorphic agent - Exogenic element

The correct answer is 1, 2 and 3.

Key Points

• Exfoliation domes - Unloading: Exfoliation domes are formed due to the unloading of overlying rock, which reduces pressure and causes the outer layers to peel off.
• Tors - Thermal expansion: Tors are large, free-standing rock outcrops formed by the thermal expansion and contraction of rock in areas with significant temperature variations.
• Geomorphic agent - Exogenic element: Geomorphic agents such as water, wind, and ice are exogenic elements that shape the Earth's surface through processes like erosion, transportation, and deposition.
• All the given statements correctly match the respective weathering processes and geomorphic agents.

Additional Information

• Weathering: The process of breaking down rocks, soils, and minerals through contact with Earth's atmosphere, water, and biological organisms.
• Types of Weathering: Weathering can be physical (mechanical), chemical, or biological, each involving different processes and agents.
• Exfoliation: A physical weathering process where layers of rock are peeled away due to pressure release, commonly seen in granite domes.
• Thermal Expansion: A physical weathering process where rocks expand and contract due to temperature changes, leading to fracture and disintegration.
• Geomorphic Agents: External forces like water, wind, ice, and waves that shape the Earth's surface by eroding, transporting, and depositing materials.
