The youngest mountains, also the highest in the world, Old mountains, in contrast, have rounded peaks and slopes. Deposition occurs when the agents (wind or water) of erosion lay down sediment. Complete step-by-step solution: Old fold Mountains are not less than 100 to 500 million years old, Young Mountain Belts are less than or equal to 100 million years old. Old fold mountains are lower than young fold Mountain, Young fold mountains are higher than Old fold mountain. Old fold mountains have a gentle slope; young fold mountain has a rugged slope. Rift valleys are lengthy-long, narrow depressions on the earth’s surface bordered by parallel faults. Block mountains are created when the tensional forces make the plates on the earth’s crusts move indifferently. Block mountains are also known to be Horst. A rift valley is also known to be graben. Some mountains in the block Mountain range rise over 12,000 feet. In Rift valley systems, the mountains are separated by deep valleys. Sometimes the valleys are wide basins. Erosional plains are created due to agents of degradation. Depositional plains are created due to the depositional recreation of the agents of gradients. A depositional plain is one that is smooth because of soil and rocks. An erosional plain is a component that has been flattened by the activity of soil and rock away from a higher feature. Intermontane plateaus are plateaus that are enclosed by hills and mountains from all sides and directions. Piedmont plateaus are the plateaus that are covered by plains and on one side mountains. Intermontane plateaus are the biggest and highest in the world. The southern plateau is also known as the continental plateau. An example of Intermontane plateaus is the Tibetan plateau. An example of the Southern plateau is the Antarctic plateau. Note: A rift valley is a straight type of swamp between the few good countries' mountain ranges made by the activity of the topographical cracks or blames. They are framed by the disparity plate limit Models incorporate the mid-maritime edges, eastern pacific ascent, and the Africa fracture valley. The Plateau of Tibet and the Plateau of Mongolia are the two intermontane levels in Asia.
