Gradational processes Weathering=breakdown of material in place Gradation=leveling of land degradation (erosion)=tshem tawm highs transport=txav ntawm cov khoom aggradation (deposition)=filling in lows Tectonic txheej txheem tsim los ntawm roughen lub ntiaj teb Gradational rog theem tawm highs thiab sau nyob rau hauv lows …
Qhov twg ntawm cov txheej txheem hauv qab no yog cov txheej txheem gradational?
Exogenic geomorphic txheej txheem muab lawv lub zog kawg los ntawm lub hnub tshav kub. Piav. Kev teeb tsa ntawm qhov chaw ntawm lub ntiaj teb yog hloov los ntawm cov txheej txheem geomorphic. Huab cua, huab cua ntau thiab yaig thiab tso tawm yog cov piv txwv ntawm cov txheej txheem geomorphic exogenic.
Peb hom txheej txheem gradational yog dab tsi?
Muaj peb txheej txheem ntawm gradation, lawv yog huab cua, thauj, thiab tso nyiaj. Huab cua yog txheej txheem dav dav uas cov pob zeb tawg thiab hnav tawm ntawm lub ntiaj teb nto.
Qhov twg ntawm cov txheej txheem hauv qab no yog txheej txheem gravitational?
Teb: Mass txav mus los cov pob zeb khib nyiab hauv qhov chaw nqes los ntawm kev cuam tshuam ncaj qha ntawm lub ntiajteb txawj nqus. Cov no suav nrog kev nkag, ntws, swb, thiab poob.
Dab tsi yog ob txheej txheem cuam tshuam nrog kev ua kom tiav?
Ob tug txheej txheem yog denudation thiab aggradation.
