Question

Which of the following is a likely explanation for why there is limestone near the summit of Mount Everest, the tallest mountain on Earth?
The limestone forms during metamorphism related to mountain building.
The limestone was formed under the pressure of mountain glacial ice.
The limestone found at the top of Mount Everest was formed in an ocean.
The limestone is the result of an igneous intrusion.

Answer 1

Answer:

The limestone found at the top of Mount Everest was formed in an ocean

Explanation:

The Himalayan Mountain Range, thus its highest peak Mount Everest as well, have been formed as a result of the collision between the Indian and Eurasian tectonic plates. The Indian plate, once it separated from Gondwanaland, started to move toward Eurasia. As it was getting closer, the plates started to push against each other. Since the boundary has been in the ocean, the ocean floor started to lift up first because of the immense pressure. As the plates continued to push against each other, the surrounding area was gradually pushed up, so what was once an ocean floor and lowlands was slowly becoming a mountain range. This resulted in limestone rocks that were formed in the ocean to be moved up for several kilometers and to become part of the highest mountain range in the world, providing us with another good proof of the continental drift theory.
