GENERAL GEOLOGY

Detailed explanation-1: -The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.

Detailed explanation-2: -The tilted or folded layers were eroded before the horizontal layers formed above them. The rock layers above an angular unconformity may be millions of years younger than those below it. Folding, tilting, faults, intrusions, and unconformities all disturb rock layers.

Detailed explanation-3: -The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

Detailed explanation-4: -The Law of Original Horizontality suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed. This allows us to infer that something must have happened to the rocks to make them tilted. This includes mountain building events, earthquakes, and faulting.
