kasutati paekivi
hoonete
ehitamisel. Näiteks
paljud Tallinna
vanalinna hooned
on ehitatud
paekivist. Samuti

See koosneb orgaanilisest ja
mineraalsest ainest. Orgaanilise osa
moodustavad peamiselt vetikate ning
organismide jäänused. Mineraalse osa
moodustavad erinevad mineraalid.

mineraalide osakesed, nimelt kvartsi,
paekivi jt osakesed.
26. Liiv võib olla valget, helepruuni,
oranži ja isegi rohelist värvi.
27. Liiva kasutatakse ehituses ja tööstuses.
Näiteks liiva kasutatakse nii betooni kui
ka krohvi valmistamisel.
Klaasliivast tehakse klaasi.
Niiske liivaga meeldib mängida lastele.
