Due to the change of the Earth’s crust, it led to a series of cracks and mountain-forming activities, and so did the eruption of volcanoes, they have formed mountain ranges.
With the rocky mountain ranges, their composition of the materials can be very different, and there are parts in such rocky mountains that are easily weathered and then dissolve into the groundwater.
