Answer and Explanation: 1. Llano Uplift 9. An island of rock excitement adrift in a sea of Cretaceous limestones whose only redeeming value is the oil in them. The four forces of erosion are water, wind, glaciers, and gravity. During homogeneous thickening with erosion that is elevation-dependent, the initial depth from which rocks can be exhumed is only determined by the density distribution in the column and is independent of erosion or thickening rates. Uplift and Subsidence. Each of these domains contain distinctive rock types and ages and were either erupted, intruded, or deposited in three separate areas and later tectonically juxtaposed during the Grenville Orogeny. Rolling Plains 10. These processes can occur over an enormous range of timescales. The term topography is used to describe the changes in elevation over a particular area and is, generally speaking, the result of two processes: deposition and erosion.
