In the big and famous canyon found in Australia
you may find caves made of sandstones. These caves are
exceptionally found there and can show the many stages through
which these rocks have gone. They are different in colour, going
from grey to orange red. The stones of which the caves are made
of, as seen in the picture, are sedimentary rocks and are able
to store great quantities of water. They are found in every
small corner of the great canyon. |
