Answer :
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.
Final answer:
Limestone near the summit of Mount Everest indicates that the mountain was once under an ancient ocean, and the rock was upthrust due to the collision of tectonic plates.
Explanation:
The presence of limestone at the summit of Mount Everest is evidence of the mountain's geological past. The most likely explanation for this limestone is that it was formed in an ancient ocean. Over millions of years, oceanic sediments containing the remains of marine organisms were lithified into limestone. Later, due to the collision of the Indian Plate with the Eurasian Plate, these sedimentary rocks were thrust upward to form the Himalaya mountain range. Consequently, what was once the bottom of the sea became the highest peak on Earth. This geological process is an example of plate tectonics at work and is supported by the discovery of marine fossils at such high altitudes.
