Ziso reSahara ndiyo geological formation inowanikwa mugwenga ine zita rimwechete. Iyo inonakidza uye inonzwisisika chimiro, pasina kupokana. imwe yeanonyanya kuzivikanwa geological formations papasi. Ichi ndicho chikonzero chakatora pfungwa dzemasayendisiti nevatsvakurudzi, asi mumakore achangopfuura yakakwezvawo kutarisa kwevashanyi vanoda kukoshesa ichi chishongo chemugwenga nemaziso avo.
Zvese zviri pamusoro zvinopfuura chikonzero chakakwana chekuti isu tipe chinyorwa ichi kutaura nezve Ziso reSahara, kubva. kuti yakaumbwa sei kunyange zvarinoreva mungano kana kuti zvaro basa resainzi. Saka usapotsa zvinozotevera.
Ziso reSahara
Ziso reSahara rinozivikanwawo se Richat chimiro nekuda kweiyo French geologist Michel Richat, mumwe wekutanga kudzidza yakasarudzika geological kuumbwa kwegwenga. Chimiro chayo chedenderedzwa chinoita chishongo chezvisikwa icho masayendisiti nevashanyi vanoda kuona.
Izvi zvakadzika geological kuumbwa zvine a dhayamita anenge 50 makiromita, inogona kuonekwa kunyange kubva muchadenga. Iyo inozivikanwa se "ziso reSahara" nekuti kubva kumusoro kwayo yakasarudzika chimiro inopa kutaridzika kweziso pakati pegwenga.

Kubatanidzwa kwayo mutsika nengano
Munhoroondo yese, Ziso reSahara rakagadzira a kukwezva kukuru mumunhu. Uye chinhu chose chinofadza munhu chakaputirwa mungano, dzidziso uye chinosanganisirwa mutsika dzeimwe nzvimbo. Uyezve, dzimwe tsika dzakaibatanidza nengano dzekare, kuva nzvimbo yesimba, nzvimbo inoyera.
Marudzi anotama-tama akagara munzvimbo iyoyo yerenje ane akarondedzera ngano dzakatenderedza nzvimbo iyoyo, chimwe chinhu chakawedzera ngano yacho. Asi hazvisi zvose zviri munyika yekare. Munguva yedu, munguva yemazuva ano, dzidziso dzakasiyana-siyana uye nyaya dzinonakidza dzakagadzirwa pamusoro pechimiro ichi. Zvasvikirwa zvine chekuita neAtlanteans kana kunze kwenyika. Kunyange, mukuodzwa mwoyo kwevamwe, idzi hadzisi chimwe chinhu kunze kwedzidziso dzisina hwaro hwesayenzi idzo dzakaita kuti Ziso rikurumbire uye zvakaita kuti vanhu vakawanda vade kurishanyira.
Kuumbwa uye kukukurwa
Kuumbwa kwayo kunotangira mabhiriyoni emakore apfuura, mu Yaiva precambrian. Kubva ipapo kusvika zvino, nhevedzano yemaitiro eiyo geological yakaitika, kusanganisira kuputika kwemakomo, tectonic mafambiro kana erosion maitiro akaumba nzvimbo kusvika nhasi.
Tectonic chiitiko chakasimudza matombo ematombo achigadzira dome, kukukurwa kwemhepo nemvura kwakabvisa kuumbwa uku kwezvinyoro zvinyoro, zvichisiya chikamu chedombo chakaomesesa. Inzira yakareba zvekuti muhupenyu hwemunhu takatadza kuona shanduko munzvimbo iyoyo. Uyu muenzaniso wekuti sei Nyika iri mukushanduka-shanduka.
Mukuwedzera, Ziso reSahara rinotipa a kukwezva kwekuona panguva ino murenje, asiwo hwindo mune yakapfuura yekusikwa kwezvikamu zvePasi crust, yekushanduka kwePasi. Inotipawo zvinongedzo pamusoro pemamiriro ezvinhu pasi pano pamamiriyoni emakore apfuura.
Kukosha kwesainzi kweZiso reSahara
Kukosha kweZiso reSahara nhema, saka, kwete chete mukukwezva kwayo kwekuona (iyo inonyanya kukosha), asi mune zvose zvinogona kuzarura kusayenzi. Chimiro chinopa mikana yakasarudzika yekudzidza geology, geomorphology uye maitiro anoumba mamiriro land. Nyanzvi dzeGeologist dzakashandisa kuumbwa uku kuongorora nhoroondo yeGeology yePasi, mamiriro ekunze uye shanduko dzayo. Zvose izvi, kubva pakuona kwezviuru zvemakore zvakapfuura kusvika nhasi.
Iri zvakare inzvimbo yekudzidza nezvekukukurwa uye kuita sedimentation, kupa data yakakosha yekuti nzvimbo dzerenje dzinochinja sei nekufamba kwenguva. Ruzivo rwese urwu rwakakosha, kunyanya nemamiriro azvino ekushanduka kwemamiriro ekunze uye kukura kwegwenga kwematunhu akasiyana pasi rose. Zvese izvi zvinokanganisa geology asiwo huwandu hwevanhu vanogara munzvimbo idzodzo.
Iwe unoda kushanyira ziso reSahara?
Kana iwe uchida kuona iyi inonakidza kuumbwa nemeso ako, isu tiri kukupa akati wandei matipi. Chinhu chekutanga ndechekuronga rwendo rwekusvika kuMauritania uye kubva ipapo kuenda kune ziso. Zvakanakira ndezve hira mutungamiriri anoziva nzvimbo, Kune zvakare nzendo dzinobva kuNouakchott (guta guru reMauritania) kune ziso. Kuenda iwe pachako kunogoneka, asi ramba uchifunga nezvemigwagwa yakaoma uye rwendo rurefu rweanenge 450 km. Iva nechokwadi chokuti wakapfeka zvipfeko zvakakodzera uye kudzivirira zuva., pamwe chete nezvokudya uye kunyange midziyo yemusasa kana zvichidiwa. Pamusoro pazvo, tsvaga izvo zviremera zvemunharaunda zvinokurudzira panguva yegore yaunoronga kushanyira.
