Relief is simply the difference in elevation between higher point and lower point on the earth’s surface. The highest point of the earth is the peak of the Mount Everest and the lower point is Mariana trench in Pacific Ocean. The difference in elevation of the earth’s surface is due to endogenic and exogenic process operating in the earth’s crust. Relief is arranged in order according to time, process and the ways are formed (shaping or reshaping).The following are the orders of relief: First order relief; First order relief features are tectonic plates and are the largest in special extent. Two types of plates; continental plates and Oceanic plates. These are differentiated by their rock and mineral composition. Continental plates are lighter in density and are composed of granitic rock materials rich in silica and aluminum. The oceanic plates are made up of dense, basaltic rock composed of silica and magnesium. Diagram of first order relief: Second order relief; Second order relief features are the results of plate collision or divergence. Examples of the features under...
