Mu lingaliro la munthu wophweka, nyanjayi ndi malo pomwe, mutakhala pamsana ndi ndodo yosodza nsomba, mukhoza kugwira nsomba pang'onopang'ono kusiyana ndi phokoso la chitukuko. Mwanjira ina, choncho, nyanja zopanda malire padziko lapansi sizingakhoze kuwerengedwa. Koma pali nyanja zina, zomwe zimakhala ngati nyanja, chifukwa miyeso yawo ndi yaikulu kwambiri. Nyanja yayikulu padziko lonse lapansi ndi mitsinje yaikulu yamadzi, yomwe pamakhala mvula yamkuntho ndipo mafunde aakulu akukwera. Nyanja zazikuluzikulu zonse ndi zatsopano komanso zamchere.
Nyanja yaikulu padziko lapansi
Yankho la funsolo, lomwe ndi lalikulu kwambiri nyanja, silimodziwika bwino. Pambuyo pake, mukhoza kuyerekeza nyanjayi mozama, m'deralo, ndi kuchuluka kwa madzi. Chodabwitsa n'chakuti, Nyanja ya Caspian, yomwe moyenerera imaonedwa kuti ndiyo nyanja, ilidi nyanja yaikulu! Ndi iye yemwe ali ndi malo oyamba mu gawo ili. Pambuyo pake, dera lalikulu la nyanja ndi makilomita 371,000 okwana makilomita okwana 1025. Kumayambiriro kwa zaka zapitazo, dera lake linali makilomita oposa 422,000 ndipo pamapeto pa zaka zana zapitazo ali ndi kukula kwakukulu.
Ngakhale kuti Caspian ndi nyanja, madzi mmenemo ndi amchere, koma osati m'nyanja. Pali nyanja yaikulu kwambiri yamchere komwe Ulaya ndi Asia amakumana.

Kuphatikiza pa malo otchuka otchedwa Caspian mafuta, nyanjayi ili ndi nsomba zambiri. Makamaka pali zambiri sturgeon, ndipo, motero, wakuda caviar.
Nyanja yaikulu kwambiri padziko lonse lapansi
Nyanja yaikulu kwambiri ya madzi abwino ndi Baikal. Malo ake ndi kilomita 31479 kilomita. Komanso Baikal ndizozama kwambiri padziko lonse - mamita 1637. Nyanja yamapiriyi, yomwe ili pamapiri a mapiri, imadyetsa mitsinje ndi mavuvu oposa 300. Selenga ndi yaikulu kwambiri, imabweretsanso theka lakale la madzi m'nyanja. Koma mtsinje umodzi wokha umachokera ku Baikal - Angara.
Nyanja yaikulu kwambiri ya madzi abwino padziko lonse ndi yakuya kwambiri komanso yoyeretsa padziko lapansi. Ndipo kukongola kwa malo oyandikana nawo sikungowongolekeretsa kufotokozera.

Chochititsa chidwi, madzi a nyanja yaikulu kwambiri amakhala ndi mitundu ina ya nsomba ndi zomera, zomwe palibe, kupatula apa, zimapezeka m'mitembo yina. M'zaka zaposachedwa, kuopsa kwa chisangalalo ku Nyanja ya Baikal kwakhala kotchuka kwambiri pakati pa oyendayenda, am'nyumba ndi amitundu.
Mndandanda wa nyanja zazikulu padziko lapansi
Pali mtundu wa chiwerengero cha nyanja zazikulu. Ilo liri ndi mazana a maudindo. Taonani ena mwa iwo, omwe miyeso yawo ndi yaikulu kwambiri:
