Which statement best describes how region 4 will look in the future?
A)lower in elevation because the weight of nearby thrust sheets will cause this part of the continent to flex downward,forming a basin
B)higher in elevation because magma generated along a subduction zone will rise into and thicken the crust
C)close to sea level because the region's crust will be thinned by thrust faulting

Quizplus · Accepted Answer

The statement mentions the subduction zone, which suggests that there is a convergent boundary in the region. At convergent boundaries, magma generated by subduction can rise and thicken the crust, leading to uplift and higher elevation. Therefore, option B is the best choice. Option A suggests that the region will experience flexure and basin formation, which is more likely at divergent boundaries, not convergent. Option C mentions crustal thinning by thrust faulting, but this would not necessarily result in the region being close to sea level, as the elevation is also influenced by other factors such as uplift and subsidence.
