Questions to answer in this research;
What is faulting?
How was it formed?
What was its causes ?
What is its significance?
A fault is a fracture or zone of fractures between two blocks of rock.Here are types of fault.
normal fault - a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in when to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge system.
thrust fault - a dip-slip fault in which the upper block, above the fault plane, moves up and over the lower block. This type of faulting is common in areas of compression, such as regions where one plate is being subdued under another as in Japan. When the dip angle is shallow, a reverse fault is often described as a thrust fault.(thrust fault animation)Blind Thrust Fault Animation
strike fault - a fault on which the two blocks slide past one another. The San Andreas Fault is an example of a right lateral fault.(Strike-slip Fault Animation)
A left fault is one on which the displacement of the far block is to the left when viewed from either side.
A right fault is one on which the displacement of the far block is to the right when viewed from either side.
Causes of faulting
- Compression stress
Occurs at convergent plate boundaries. The plates move and crash toward each other. This is what like when two cars crash into each other.
- Tension stress
Occurs at divergent plate boundaries. The plates are drifting away from each other.
- Shear stress
Occurs majorly at transform boundaries. The plates slide past each other horizontally in opposite directions.
According to this cite(https://www.kenyaplex.com/ques...uman-activities.aspx)it state the following as the significance of faulting;
(i) Block mountains formed through faulting lead to formation of relief rainfall on the windward side which favors agriculture and forestry.
(ii) Springs occurring at the foot of fault scarps attract settlements
(iii) When faulting occurs across a ridge,it may hinder development of transport.
(iv) Faulting leads to formation of features that form beautiful scenery.
(v) Faulting leads to formation of lakes that are important fishing grounds or tourists' sites.
(vi) Faulting causes displacement of rocks which exposes minerals.
(vii) Subsidence of land as a result of faulting may lead to loss of life and property.
(viii) Faulting creates deep faults which are passages of stream jets which may be utilized for geothermal power production.
Escarpment and block mountains may form barriers which may prove difficult during the construction of roads and railway.
(ii) Features formed through faulting such as rift valley and others are a tourist attraction which earns the Kenya economy foreign exchange.
(iii) Deep faults created through faulting are passages of stream jets which may be utilized for geothermal power production.
(iv) Sometimes Springs may be formed at the base of escarpments which may attract settlement.
(v) Faulting may lead to formation of lakes which provide water for domestic,irrigation and industrial use.
Next time i will continue with faulting.
