Question

write a short note on faulting aqnd mountain range please i n eed the answer soon i

Answer 1

Fault-block mountains often result from rifting, another indicator of tensional tectonicforces. These can be small or form extensive rift valley systems, such as the East African Rift zone. Death Valley in California is a smaller example. There are two types of block mountains; lifted and sloped.

Lifted type block mountains have two steep sides exposing both sides scarps, leading to the horst and graben terrain seen in northern Europe

Answer 2

Fault blocks are very large blocks of rock, sometimes hundreds of kilometres in extent, created by tectonic and localized stresses in the Earth's crust. Large areas of bedrock are broken up into blocks by faults. Blocks are characterized by relatively uniform lithology. The largest of these fault blocks are called crustal blocks. Large crustal blocks broken off from tectonic plates are called terranes.Those terranes which are the full thickness of the lithosphere are called microplates. Continent-sized blocks are called variously microcontinents, continental ribbons, H-blocks, extensional allochthons and outer highs.
