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.
Great lakes were formed from glaciers and slowly melted creating higher water levels creating more vegetation and economic growth.
