Question

Do you consider that the making of mount rushmore is already and erosion? justify your answer​

Answer 1

Answer:

Mount Rushmore is here today because the granite erodes very slowly compared to the surrounding rocks. In the area of the memorial the hard granite creates mountains or hills and the equally tough quartzite forms knife ridges. The less resistant mica schist tends to be eroded into canyons and gullies.

Answer 2

Mount Rushmore is a result of erosional effects.

• The effect of geographical forces such as heat, deposition, uplift, and erosion combined for various years have resulted in the carving of Mount Rushmore.
• The history of the region of Mount Rushmore lies between 1.6 billion and 500 million and is unknown. However, during that time, no rocks were formed and survived.
• Mount Rushmore is a result of the deposition of marine sediments and the erosion of miles of rock formed above granite.
