5 0
The theory of magnetic anomalies provide solid proof written in the ocean floor to show that new crust was being created here. The earth's magnet field changes from time to time over periods of thousands of years. This change is record in rock.
The new rock formed along the sea floor is an accurate record of the changes in the magnetic field. Seafloor spreading occurs at divergent margins where two plates are being pulled apart. As this happens, magma upwells and new crust is formed.

A team of researchers calculates that a glacier will melt completely away in the next 100 years. Which land structure will most
Reil [10]

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).
