Question 1

Sometimes a river will flow through a structural and topographic high,such as a dome.In order for this to occur,what had to happen?

Accepted Answer

A) people must have created a channel through the feature by blasting,drilling,or tunneling. 
B) the river once flowed underground in a cave,but the roof of the cave collapsed and created a surface channel. 
C) the river was flowing through the area prior to uplift and the river was able to erode down through the feature as uplift occurred. 
D) rivers began flowing from the top of the feature-but on opposite sides.Through time,the rivers eventually joined together as a result of headward erosion,and thereby cut through the structure. 
E) a dam was constructed allowing more water to remain in the channel and the river was able to flow over the topography.
