Isihlabathi singenye yezinto ezivame kakhulu emhlabeni. Isihlabathi sakhiwe izingcezu ezincane kakhulu zamatshe. Uma izinhlamvu zesihlabathi zikhulu kunamamilimitha amabili, kubizwa ngokuthi i-gravel.
Isihlabathi sakheka eminyakeni eminingi ngamadwala aleso simo sezulu. Isihlabathi esiningi senziwe nge-quartz, amaminerali. Esinye isihlabathi sivela emadwaleni ezintaba-mlilo.
Nokho, isihlabathi sivela ezilwaneni noma ezitshalweni. Izimbaza, isibonelo, zinegobolondo elenziwe ngento efanayo namagobolondo amaqanda enziwe ngayo. Izingcezu ezincane zamagobolondo noma izinsalela zamakhorali ngokuvamile zenza ingxenye yesihlabathi, ikakhulukazi emabhishi noma embhedeni womfula.
Kunezinhlobo ezahlukene zesihlabathi: Izinhlamvu zesihlabathi sasogwadule ziyindilinga futhi zinezindawo ezibushelelezi. Lokho ungakubona ngokucacile ngaphansi kwe-microscope. Lapho umoya uziphephula, ziyakhuhlana zodwa. Izinhlamvu zesihlabathi solwandle, ngakolunye uhlangothi, ziyi-angular futhi zinendawo elukhuni.
Nokho, isihlabathi asitholakali nje ezingwadule, ogwini, nangaphansi kolwandle. Kuwo wonke umhlabathi, kunengxenye yesihlabathi. Uma umhlaba uqukethe isihlabathi esiningi, kubizwa ngokuthi inhlabathi eyisihlabathi. Zivame kakhulu eYurophu.
Abantu badingani isihlabathi?
Abantu namuhla badinga isamba esikhulu sesihlabathi ukuze benze ukhonkolo ngaso. Lokhu kudinga usimende, amanzi, nezinye izithasiselo zamakhemikhali. Basebenzisa ukhonkolo ukwakha izindlu, amabhuloho, nezinye izakhiwo eziningi.
Kodwa ungakha kuphela ngesihlabathi solwandle. Izinhlamvu zesihlabathi sasogwadule ziyimbulunga kakhulu futhi azenzi ukhonkolo oqinile, kungakhathaliseki ukuthi usimende ongakanani. Ezigwini eziningi nasezindaweni eziningi zolwandle asikho isihlabathi ngoba sesisetshenziswe saphela. Ngakho-ke isihlabathi silandwa kude ngemikhumbi emikhulu, ngokuvamile ngisho nakwelinye izwekazi.
Abantu abaningi bathanda uma kunesihlabathi esiningi ogwini. Ngezinye izikhathi isihlabathi siyanqwabelana ngenxa yalokhu. Nokho, lokhu akusizi ngalutho, ngoba umsinga uthwala isihlabathi futhi. Kufanele uhlale uyigcwalisa futhi iyintsha.
Ngenxa yokuthi isihlabathi siyadedela, lapho ugxuma amabanga amade ngokuvamile uphelela endaweni yesihlabathi. Izinto zenkundla yokudlala zivame ukwakhiwa emigodini esihlabathini ukuze ingane ingalimala uma ingase iwe. Ungakwazi futhi ukwenza okuthile ngesihlabathi. Lokhu kusebenza ebhokisini lesihlabathi lokudlala futhi nasesithombeni esenziwe ngesihlabathi.
