Bias is pretty much leaning towards one side of something. For example the election, some news channels were biased and only showed the bad sides of one candidate. By doing this they were being biased and they were leaning towards the other candidate.
When defining regions, geographers avoid using subjective information.
<h2>
Answer</h2>
The answer is Regional Metamorphism
<h2>
Explanation</h2>
In the metamorphism, the rock is altered with the effects of natural agencies. Regional Metamorphism is the type of metamorphism, where the rocks are also changes with the interaction of high pressure or heat on the open wide area instead of contact with the magma. These rocks are also changes with the overburden of plate tectonics. In this question, the large-scale folding of rocks represents Regional Metamorphism.
The long term result would be that the region where it has occurred will split and the two parts will move away from each other, the growing gap between them will be filled with water which in time will become sea, there will be significant climate changes, the one part that'll be moving into more isolated position will make life forms on it to evolve in a specific way and they will become very unique in time.
