Bulldozer

Bulldozer

My grandson, who is two years old, loves bulldozers.  Coincidentally we went on a tour of a rock quarry near our community.  It has, as you would excpect, bulldozers.  The rock quarry company is called Geneva Rock.  They have huge bullduzers that have a ripper on the back.  These rippers dig into the ground or rock and break it up.  Then the bulldozer backs up and pushes the broken up rock into a pile. 

If you wonder about what is drawn under the bulldozer, those are rock layers and I drew them in the geologic symbols for:  sandstone, shale, and limestone.  Those layers form on a desert or beach for sandstone.....  in a shallow sea for shale. . .   and in a deeper ocean for limestone.    These rock layers are seen in this pattern if the ocean was drying up there at that spot where the rock layers formed.
