How did research from the Glomar challenge help scientist support the theory of seaflooding spreading?

Answer 1

From Wikipedia:

Starting from August 1968, the Glomar Challenger embarked on a year-long scientific expedition, the Deep Sea Drilling Program, criss-crossing the Mid-Atlantic Ridge between South America and Africa and drilling core samples at specific locations. When the age of the samples was determined by paleontological and isotopic dating studies, this provided conclusive evidence for the seafloor spreading hypothesis, and, consequently, for continental drift.

Answer 2

The Glomar Challenge research helped scientists support the theory of seafloor spreading by providing direct evidence of the presence of mid-ocean ridges and magnetic striping patterns on the seafloor. This research confirmed the parallel movements of tectonic plates away from the mid-ocean ridges, supporting the theory of seafloor spreading. Additionally, the discovery of young oceanic crust near the ridges provided further evidence for this geological process.
