⏰ when
When was the first recognition of seafloor ages increasing away from mid-ocean ridges?
Quick Answer
This pattern was recognized in the early 1960s, especially by 1963.
The Full Story
By the early 1960s, oceanographers realized that rocks on the ocean floor were youngest near mid-ocean ridges and older farther away. This age pattern fit perfectly with seafloor spreading, where new crust forms at ridges and moves outward. The idea was strengthened by studies of magnetic anomalies and ocean drilling. It became a crucial part of the evidence that led to plate tectonics.
