• plates floating on the mantle
O subduction
• continental drift

Answered by GPT 3.5
The correct answer is: O subduction.

Scientists observed subduction in the ocean floor as evidence that the Pacific Ocean is becoming smaller. Subduction is the process by which one tectonic plate is forced beneath another plate, typically in a subduction zone. In the case of the Pacific Ocean, the Pacific Plate is being subducted beneath other plates, leading to the shrinkage of the ocean.
