Geography. Kumasiyanitsa dothi thanthwe?

ndi nthaka ndi miyala chiyani? Kodi phindu mu chikhalidwe ndi momwe kumasiyana ndi thanthwe nthaka, kuwerenga nkhaniyi.

mwachidule

Kuonetsera kusiyana dothi thanthwe, muyenera kudziwa tanthauzo la onse. Ngakhale kuti mapangidwe nthaka amachokera thanthwe, pakati pawo pali kusiyana Mkhalidwe amati izi ndi zosiyana thupi.

Kumasiyanitsa dothi thanthwe? Malinga ndi imodzi mwa mfundo n'zoonekeratu kuti mapangidwe dothi kumachitika pa nyanja, adatayika lubwe, ndiye, kulikonse kumene thanthwe amabwera mu kukhudzana ndi zamoyo. Kwa lingaliro ili pakati pa nthaka weathering kutumphuka ndi theoretically zotheka, komabe pali mavuto.

Nthaka: The katundu chachikulu

Nthaka ndi thupi lachibadwa ndipo ili akudzizindikiritsa makhalidwe. The morphological waukulu ali. Nthaka isiyana chonde thanthwe. Ichi ndi dera lomwe mizu wamba ndi tizilombo moyo. Nthaka isiyana ndi miyala pamaso humus wosanjikiza apindula ndi manyowa, zimene ndi osakaniza M'maso.

Nthaka: opangidwa kuchokera katundu

katundu nthaka, kafukufuku wakapangidwe kazachilengedwe, thupi ndi mankhwala, umanena. Nthaka isiyana ndi zizindikiro thanthwe monga kachulukidwe ake. yosungirako mulingo woyenera ndi galamu imodzi centimeter kiyubiki. Ngati kachulukidwe ndi apamwamba kuposa chithunzi ichi, mizu ya zomera kudzakhala kovuta ingaloŵe wosanjikiza izi, ndipo iwo adzakhala bwinja iwo.

katundu nthaka tinthu kukula yogawa ndi mineralogical zikuchokera, kapangidwe, zikuchokera M'maso. Iwo onse kukokera pamodzi mu dothi ambiri ndi pamiyala. Koma nthaka ndi osiyana ndi dongosolo thanthwe, humus kaja ndi osakaniza zace.

kholo miyala

Iwo amatchedwa kholo. Ndi miyala imene mapangidwe dothi kumachitika. Iwo amasiyana chiyambi, zikuchokera, kapangidwe ndi katundu. nthaka onse anapita, umene unakhazikitsidwa pa thanthwe ili.

Kumasiyanitsa dothi thanthwe? Pa siteji koyamba dothi mapangidwe miyala kupereka kwa iwo amadza yaikulu. Ku m'bado wa zinthu mankhwala iwo zimadalira chonde wachibadwa wa nthaka. Mwachitsanzo, mtundu wina wa nthaka, amene anapanga pa miyala osiyana zingasiyane.

Kodi anapanga miyala?

Pansi pa dzikoli tichipeza miyala, amene m'magulu awa:

• Igneous kapena chachikulu-crystalline miyala - izo chilled, kenako Unalimbitsa chiphalaphala. Iye akanakhoza amaundana akuya kapena kufika padziko lapansi. Chotero thanthwe lalikulu, wandiweyani kapangidwe. Iwo amakhala peresenti makumi asanu ndi anayi mphambu zisanu ya unyinji wonse wa miyala, nthaka-kupanga koma sanatero. Kuchotserapo milandu kawirikawiri m'madera a mapiri.
• miyala Metamorphic anapanga igneous kapena nyanja. Izi kusintha wosanjikiza. Ngati wakale nyanja miyala anayenera poyera kuti kutentha ndi kuthamanga kwa iwo akhoza kukhala ofanana ndi thanthwe igneous, amene si kwathunthu mbisoweka zizindikiro matope. Miyala imeneyi ndi za nsangalabwi, PAMASILETI, quartzite, conglomerates. Alanda mbali yaikulu ya padziko lapansi, koma phindu ndi otsika kwa nthaka. Kuwonetseredwa makamaka m'madera a mapiri.
• miyala nyanja yodziwika ndi yakuti mu nthawi yathu pa iwo ndi njira ya mapangidwe nthaka. Iwo strata anasonkhanitsa pansi pa nyanja, nyanja, mtsinje, mabeseni nyanja ndi zigwa. Miyala poyera kuti weathering. The mankhwala a madipoziti awo, komanso zotsalira za zamoyo amatchedwa nyanja miyala. Mwa iwo, mu mapangidwe nthaka m'dambo carbonate kumathandiza kwambiri.

ndi weathering Kodi miyala?

Dothi n'kupanga miyala anapanga mogwirizana kwambiri ndi weathering, mayendedwe ndi mafunsidwe a weathering mankhwala.

Weathering njira ndiwo anthu amene zimabweretsa kusintha zizindikiro Mkhalidwe ndi kachulukidwe a miyala ndi mchere umene iwo analemba. Chifukwa cha pasukuluyi, zigawo chapamwamba lithosphere kusintha kapangidwe kake zakuthupi ndi n'kukhala weathering kutumphuka.

mitundu weathering

The miyala nthaka-n'kupanga, kapena ngati iwo ali kutchedwa, kholo, kodi anapanga mchikakamizo cha ndondomeko weathering, ndiwo wa mitundu itatu.

Thupi - ndi pamene miyala ndi mchere awo constituent zagonjetsedwa kwa kugawikana makina, koma mipweya awo amakhalabe sichinasinthe. The chifukwa cha ndondomekoyi ndi mphamvu kawetedwe ndi pochitika mpweya kuzengereza madzi. Yotsirizira ali chachikulu kowononga, makamaka pa kuzizira.

Chemical weathering N'zosatheka madzi, mpweya ndi mpweya. Madzi ndi mphamvu zosungunulira mchere kuti apange thanthwe. kuwonongeka awo uli wachangu pa okwera kutentha ndi machulukitsidwe thanthwe ndi mpweya. Kumasiyanitsa dothi thanthwe? The chifukwa cha mankhwala weathering wa miyala limayenda ndi mchere latsopano ndi kupeza katundu monga mphamvu mayamwidwe, zamalumikizidwe ndi ena. Koma thanthwelo alibe chuma kwake nthaka kokha - chonde.

Tizilombo weathering - chomaliza ndondomeko kukonzekera kwa nthaka. nthaka ndi osiyana ndi thanthwe? Kuwonongedwa kwa miyala chikuchitika ndi nawo zamoyo, zomwe M'malo mwake, alemere nthaka, kupanga gawo latsopano la izo. Zamoyo otengedwa mchere koyenera kuti tsogolo la mapangidwe nthaka thanthwe.

dothi phindu

Ntaka mbali yofunika kwambiri mu moyo wa munthu. Iwo amaphunzira osati mavuto ulimi. Wodziwa za katundu dothi, ife angathetse zomangamanga ndi kumanga mavuto ambiri, matenda, ndi miyala migodi. Kukhala nkhalango, malo wobiriwira m'matawuni ndi m'mizinda, nayenso, n'zosatheka popanda kudziwa za dothi.
