Exogenetic Processes Part-1 (Part 1) — Flashcards

Answer

Exogenetic processes are external processes that occur on the earth's surface due to forces like solar energy, gravitational force, and kinetic energy. These processes include weathering, erosion, tra…

Answer

Primary and secondary landforms are formed due to internal movements (e.g., continents, mountains, plateaus, plains). Tertiary landforms are formed due to external processes like weathering, erosion, …

Answer

Weathering is the breaking or weakening of rocks due to natural phenomena. It is the process by which rocks are broken down into smaller particles without being moved from their original location.

Answer

The three main types of weathering are: 1) Mechanical (Physical) weathering - dominant in arid climates, 2) Chemical weathering - more effective in humid climates, 3) Biological weathering - occurs du…

Answer

Exfoliation is a process where the outer layers of rocks fall apart from the main rock due to differential heating. The exposed part heats more while the inner part remains cooler, causing the outer l…

Answer

Frost weathering occurs when water accumulated in rock cracks freezes in areas where temperatures drop below 0°C. When water freezes, its volume increases, creating tension in the rocks that causes th…

Answer

Crystal growth weathering occurs in rocky coasts where alkaline seawater enters rock cracks. Soluble materials dissolve creating holes, alkaline water evaporates leaving crystals that occupy more spac…

Answer

Granular weathering occurs in rocks like sandstone and conglomerate when water penetrates them. These rocks are formed by pressure on sand particles held together by mud. Water makes the particles loo…
