Question 1 Report

Which of the following best explains why the older fold mountains are much lower and less rugged than the newer ones?

The newer fold mountains are situated in areas of active earth movements

The effects of earth movements resulting in mountain building are much greater nowadays than they were during the period of folding

The newer fold mountains, in contrast to the older ones, are made up of more resistance rocks

the older fold mountains have been subjectd to the forces of denudation for longer, geological periods

Most of the newer fold mountains are situated in the interior parts of continents where they are free from constant sea erosion

Answer Details

The answer is D - The older fold mountains have been subjected to the forces of denudation for longer geological periods. Denudation refers to the wearing away of the Earth's surface by processes such as erosion and weathering. The older fold mountains have existed for much longer periods and have been exposed to these processes for a longer time, which has resulted in them being lower and less rugged than the newer ones. In contrast, the newer fold mountains are still being formed and have not yet had as much time to undergo denudation.
