Qhov twg chalk ( permeable ) ntsib ib qho impermeable pob zeb (feem ntau av nplaum) springs tsim thiab tuaj yeem pom thaum cov dej ntws pib ntws ntawm qhov chaw. Chalk yog eroded los ntawm kev daws.

Hauv qhov no, yog Chalk ntxeem tau lossis permeable?

Chalk yog tsis muaj zog tshaj granite thiab nyhav tsim ntau maj mam dov toj thiab hav. Chalk yog ntxeem tau thiab permeable , yog li muaj dej me me heev thiab cov kwj ha tsim nyob rau lub sijhawm dhau los tam sim no feem ntau 'qhuav'.

Qhov thib ob, yog vim li cas chalk muab faib ua pob zeb ntxeem tau? Chalk yog heev ntxeem tau , yog li dej ntws nrawm nrawm ntawm cov nplej. Cov porosity ntawm a pob zeb yog qhov ratio ntawm cov pob zeb uas yog ua los ntawm qhov chaw nruab nrab ntawm cov nplej (hu ua pores ), voids thiab tawg.

Khaws qhov no hauv kev xav, dab tsi pob zeb yog permeable?
