FAULTING

Hey there,

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

  1. 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.

  1. Tension stress

Occurs at divergent plate boundaries. The plates are drifting away from each other.

  1. 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.

Thank you for reading.

Hi Mary,

Great research! It was very thorough and detailed, and I appreciate the pictures and animations you attached, as being able to see visuals of your explanations made it easier to understand. I like how you didn't just say what faulting was, but you also researched the causes and its significance.

Here are some more websites that discuss faulting:

Keep up the good work!

Hey Mary,

This was quite the informative post! You went into the different types of faults and stresses which was nice. I'd love to see more of how people study these faults and what information about the past, present, and future we can get from this. Here's a website I found that I think you should take a look at:

Keep up the good work!

Hi Mary,

I thought this post was spectacular! You hit right on point with what you were trying to explain. It was interesting to read that there are different types of faults. I have heard of the San Andreas fault line, but I never knew it was a strike fault. Maybe you could looker into some famous faults worldwide! 

These are some links that talk about popular faults:

Great work!
