Cov eroded minerals thiab cov ntsiab lus ua rau lawv txoj kev mus rau hauv cov kwj thiab dej ntws uas tsim los ntawm lub dej khov thiab cov khoom zoo heev tau raug tshem tawm hauv dej thiab nqa mus rau hauv dej kom txog thaum lawv ncav cuag dej hiav txwv.
Tsis tas li lo lus nug yog, puas yog pob zeb av nplaum unconsolidated?
Till, tseem hu ua pob zeb av nplaum , yog mix tsis sib koom sediment nrog ntau yam ntawm grain loj ( av nplaum - pob zeb ). Ntau pob zeb av nplaum yog ntawm ib tug xiav-grey kom txog rau thaum raug huab cua uas ua rau ib tug transformation rau ib tug xim av.
Yuav ua li cas glacial kom tsim tau?
