Which vessel was significant in collecting core samples from the mid-ocean ridge?

1. HMS Challenger

2. USS Nautilus

3. Glomar Challenger

4. RV Ocean Explorer

The correct answer is: Glomar Challenger

The Glomar Challenger is significant in collecting core samples from the mid-ocean ridge because it was specifically designed for deep-sea drilling and played a crucial role in the history of oceanography during its operation from 1968 to 1983. This vessel was equipped with advanced drilling technology that enabled researchers to obtain sediment and rock core samples from the seabed, providing invaluable information about the geological history of the ocean floor. The core samples collected by the Glomar Challenger helped scientists to understand plate tectonics, the age of oceanic crust, and the processes occurring at mid-ocean ridges. The data obtained from these samples contributed to the development of the theory of seafloor spreading and provided insights into the Earth's geological history. In contrast, other vessels mentioned, like the HMS Challenger, conducted significant oceanographic research but did not focus specifically on core sampling of mid-ocean ridges. The USS Nautilus is well known as the first nuclear submarine to complete a submerged transit beneath the North Pole, but it didn't engage in deep-sea core sampling. RV Ocean Explorer may partake in various marine research activities, but it does not hold the historical significance in core sampling that the Glomar Challenger does. Thus, the Glomar Challenger stands out as
