Question

Which of the following landforms is not associated with glaciation?
A. Hanging valley
B. Moraines
C. Inselberg
D. Drumlin

Answer 1

Hint: Landforms are, in simple words, small and medium tracts or parcels of the Earth’s surface. Glaciers on the other hand are masses of ice and snow moving sheets over the land or as linear flowing down the slopes of mountains or through valleys.

Complete answer: Glaciers are formed when continuous snowfall occurs upon the upper surface in the zone of the highest elevation. These snow piles up every year in places where the rate of loss of snow by ablation in summer is less than the rate of receipt of snow. As time goes, it slowly hardens to round ice pellets and each year new layers of snow bury the previous layers.

Now let us examine the options:
Option A - A hanging valley is higher than the main valley and is associated with U-shaped valleys. This type of valley is formed when the lower valley has a greater rate of erosion. As a result, one valley is elevated than the other, with one end open to the valley below.
Option B - Littered debris at the edges or the end of the glacier or between glaciers are called moraines. Moraines are rock debris or till that is carried or deposited by a moving glacier.
Option C - Inselberg is the remnant of a mountain which has come into existence as a result of wind erosion.
Option D - Drumlins are smooth oval-shaped ridge-like features. They are mainly composed of till with some masses of gravel and sand. Drumlins are formed due to dumping of rock debris beneath heavily loaded ice through tissues in the glacier.

Thus, the correct answer is option C.

Note: The event of inselbergs infers massive varieties in the paces of degradational activities on the land surface. These structures are one of a few assortments of landforms called paleo forms that can survive with little modification for thousands or millions of years.
