Image Fault Horst Graben.svg thumb Faultblock geology Faultblock landforms mountains, hills, ridges, etc. are formed when large areas of bedrock are widely broken up by fault geology faults creating large vertical displacements of continental crust. Vertical motion of the resulting blocks, sometimes accompanied by tilting, can then lead to high escarpment s. These mountains are formed by the Earth s crust being stretched and extended by tension physics tensional forces . Faultblock mountains commonly accompany rift ing, another indicator of tensional tectonic forces. The uplifted blocks are called block mountains or Horst geology horsts . The intervening dropped blocks are termed graben .These can be small or form extensive rift valley systems. Two types of block mountains are lifted and tilted. Tilted type block mountains have one gently sloping side and one steep side with an exposed scarp, and are common in the Basin and Range Province Basin and Range region of the western United States . Level blocks lead to the Horst geology horst and graben terrain seen in northern Europe . Lifted type block mountains have two steep sides exposing both sides scarps. Notable Examples The Great ...

Image fmrockc.jpg Rock right thumb 200px An element of rock under stress Fault mechanics is a field of study that investigates the behavior of geologic fault s. Behind every good earthquake is some weak rock. Whether the rock remains weak becomes an important point in determining the potential for bigger earthquakes. On a small scale, fractured rock behaves essentially the same throughout the world, in that the angle of friction is more or less uniform see Fault friction . A small element of rock in a larger mass responds to stress physics stress changes in a well defined manner if it is squeezed by differential stresses greater than its strength, it is capable of large deformations. A band of weak, fractured rock in a competent mass, can deform to resemble a classic geologic fault .
