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.
