WEATHERING & EROSION
NCERT notes ( Study Material ) on of import topics for the CDS, NDA, AFCAT written exam. These notes volition equally good hold out useful for other competitive exams like, UPSC Civil Services, State Civil Services exams, Bank PO, SSC as well as and therefore on. ( Check Other NCERT Notes Here )
WEATHERING
Weathering is an inwards situ procedure inwards which rocks interruption into pocket-size particles due to the weather. It does non involve the removal of stone material.
Heat, cold, frost, fog conditions plant on the stone to expand as well as contract 1 time again as well as again, which results into the separation of the layer as well as the particles of the minerals. This consummate procedure of known equally weathering.
TYPES OF WEATHERING
- PHYSICAL OR MECHANICAL WEATHERING : caused past times the effects of changing temperature on rocks, causing the stone to interruption apart.
- CHEMICAL WEATHERING : caused past times pelting H2O ( slightly acidic ) reacting alongside the mineral grains inwards rocks to course of written report novel minerals ( clays ) as well as soluble salts.
- BIOLOGICAL WEATHERING : caused past times Men, Animals, Insects as well as Vegetation.
EROSION
Erosion is the displacement of weathered stone from 1 house to another. It is a procedure past times which reason as well as stone particles are worn away as well as moved elsewhere past times gravity, or past times a moving carry agent similar wind, H2O or ice.
AGENTS OF EROSION
- GRAVITY : down-slope displace of issue stone as well as reason due to gravity.
- WIND : air current takes away dry out as well as lite sand particles from 1 house to another.
- WATER : transports millions of tonnes of sediment everyday, along rivers, coasts, as well as fifty-fifty inwards the deep oceans.
- ICE : displace of H2O ice downhill causes erosion of underlying rocks.
HOW IS EROSION DIFFERENT TO WEATHERING ?
Erosion involves removal of company cloth past times a transporting agent. Weathering is the breakdown of stone into fragments at the Earth’s surface. Note : No displace is involved inwards weathering.Buat lebih berguna, kongsi:
