Question

A team of researchers calculates that a glacier will melt completely away in the next 100 years. Which land structure will most likely be left behind after the glacier melts?
A)an arch
B)a deep canyon
C)a table mountain
D)a valley

Answer 1

Answer:

Option (C)

Explanation:

Table Mountains are generally considered to be one of the oldest mountains that are present on earth. They are nearly six times older than the Himalayas. It started to form about 800 million years back when the rock sandstone were created under the the surface of the water. These rocks were uplifted due to the upward thrust produced by the magma, as a result of which it slowly started to form volcanoes. Over the years, the earth has experienced much cooler temperature due to the occurrence of ice age events, due to which these rocks were crystallized forming intrusive igneous rock such as granite. This uplifted mountains and volcanoes were covered with ice and over a due course of time, because of the overlying weight, the mountains became flat and all of the ice were melt, thereby forming the table mountains.

Thus, it can be considered that the table mountains are formed after all of the glaciers are melt.

Hence, the correct answer is option (C).
