Weathering and Erosion

सारांश

Weathering breaks rock in place; erosion removes and transports the resulting material by water, wind, ice or gravity.

क्यों और कैसे होता है

कारण और संदर्भ

Weathering breaks rock in place; erosion removes and transports the resulting material by water, wind, ice or gravity. The governing relationship is: Physical, chemical and biological weathering weaken material, after which moving agents entrain, transport and deposit sediment.

यह कैसे काम करता है

Physical, chemical and biological weathering weaken material, after which moving agents entrain, transport and deposit sediment.

मुख्य तथ्य

• Weathering is in situ; erosion involves removal.
• Hydrolysis, oxidation, carbonation and solution are chemical weathering processes.
• Abrasion is wearing caused by transported particles scraping a surface.

ज़रूरी शब्द

• weathering
• erosion
• abrasion
• mass wasting
• denudation

भूगोल से जुड़ाव

River incision and slope wash in the Himalaya supply sediment to the Ganges-Brahmaputra delta. This illustrates how weathering and erosion varies by location, scale or environmental context.

बांग्लादेश से जुड़ाव

Riverbank erosion along the Jamuna and braided channels displaces land and settlements, while weathering supplies sediment from uplands.

• Physical, chemical and biological weathering weaken material, after which moving agents entrain, transport and deposit sediment. Use river incision and slope wash in the himalaya supply sediment to the ganges-brahmaputra delta. as a named application in a comparative answer.

आम गलतफ़हमियाँ

• Deposition is not erosion; it is the settling of transported material.
• Weathering does not require movement of material.
