Problem: Cross Section of Rock Layers
A quarry is an open pit from which rock can be obtained by digging, cutting, or blasting. The quarry shown below cuts through several layers of sedimentary limestone rock, labeled W through Z. Some of the rock from the quarry is crushed to make gravel of various sizes. The rock and gravel are used in the construction of buildings and roads. Large diesel machines and trucks remove the rock and gravel and transport it to construction sites.
Before the quarry was dug, the land contained more vegetation. What impact has this change most likely had on the local ecosystem? Need Assignment Help?
