Describe the formation of block mountain and give example of a block mountain and rift valley?
Block mountains are formed when geological faults cause blocks of the Earth's crust to move vertically, leading to the formation of tall mountain ranges. An example of a block mountain is the Sierra Nevada in California, USA. Rift valleys, on the other hand, are formed by the stretching and thinning of the Earth's crust, leading to the development of deep valleys. The East African Rift Valley is a well-known example of a rift valley.
