If the hanging wall rises relative to the footwall, you have a reverse fault. Explain. Geography terms and Definitions starting with O | UPSC … The exhumation and growth of the Himalaya is a continuous process that results predominantly from reverse faults in which the rocks on the lower surface of a fault plane move under relatively static rocks on the upper surface, a process called Underthrusting … The horsts make block-like plateaus or mountains often with flat top but steep sides. C)Reverse faults-It is also called thrust faults, slide one block of crust on top of another. Three kinds of faults: Strike-slip, Normal fault and Thrust (reverse) faults. Displacement of rock block horizontally along fault plane d. Stege fault iv. When two normal faults occur, the narrow block that dropps down between them is a graben, and elevated region is a horst. Reverse fault done clear. Que. They have rounded features (due to denudation). Reverse fault done clear. Old fold mountains had their origin before the Tertiary period (tertiary period started 66 million years ago). Sometimes in the shower. Now explain the significance of faults and the process in Plate Tectonics. The Basin and Range Province in North America and the East African Rift Zone are two well-known regions where normal faults are spreading apart Earth’s crust. Examine. Reverse faults are exactly the opposite of normal faults. Tension causes the central portion to be let down between two adjacent fault blocks forming a graben or rift valley, which will have steep walls. It may be mentioned that in a reverse fault the rock beds on the upper side are displaced up the fault plane relative to … Tag: faults in the upsc system. Background: The exhumation and growth of the Himalayas is a continuous process that results predominantly from reverse faults in which the rocks on the lower surface of a fault plane move under relatively static rocks on the upper surface, a process called underthrusting of the Indian plate beneath its Eurasian counterpart. Movement is upward instead of downward. Alpine fold mountains belonging to the Tertiary period (66 million years ago to present) can be grouped under the new fold mountains category since they originated in the Tertiary period. On the basis of the period of origin, fold mountains are divided into very old fold mountains, old fold mountains and Alpine fold mountains. When the crustal rocks are displaced due to movement caused by the endogenetic forces along a plane, the resultant structure is called a fault and the process is known as faulting. Explain the various factors controlling the temperature distribution on our planet. Landforms made by Normal fault are: Rift Valley or Graben Top layers are worn out due to erosional activity. What is Diastrophism? The transform boundary ends abruptly and is connected to another transform, a spreading ridge, or a subduction zone. Normal fault: create space. Epeirogenic Forces? In a normal fault, the hanging wall (displaced block of crust) moves. For e.g. All rights reserved | Terms & Privacy | Amazon Affiliate Disclosure. Movement of both the rock blocks towards each other c. Lateral fault iii. “Reverse faults” is like a geological thing, in like the plates, or like in an earthquake. A special class of strike-slip fault is the transform fault or transform boundary. Change ), You are commenting using your Twitter account. Posted on March 22, 2014 March 19, 2014. The plane along which the rocks blocks are displaced is called fault plane. Change ), You are commenting using your Google account. These faults are commonly found in collisions zones, where tectonic plates … Change ), You are commenting using your Facebook account. Fold mountains are mostly found along continental margins facing oceans (C-O Convergence). Main Boundary Thrust: It is a reverse fault of great dimensions which extends all the way from Assam to Punjab and serves to separate the outer Himalayas from the lesser Himalayas. A downthrown block between two normal faults is a graben. Normal fault – when the faulting is a result of tensional forces, the rock on the two sides of the fault plane are pulled away from each other . Folding is seen rarely seen in metamorphic rocks (Note: it’s rare and not absent) because they are hard and brittle, instead of folding they break and form reverse fault.
