Question

How do sediment cores from the ocean floor support the concept of seafloor spreading?

A. Sediment cores reveal a lack of any seafloor features, supporting the idea that the ocean floor is not actively changing.
B. Sediment cores provide evidence of ancient civilizations on the seafloor, indicating human activity in the past.
C. Sediment cores contain layers of progressively younger sediments as they approach mid-ocean ridges, confirming the process of seafloor spreading.
D. Sediment cores disprove the concept of seafloor spreading by showing a consistent layer of sediment across the ocean floor.

Answer 1

Sediment cores from the ocean floor support the concept of seafloor spreading by showing layers of progressively younger sediments as they approach mid-ocean ridges.

Step-by-step explanation:

Sediment cores from the ocean floor support the concept of seafloor spreading by providing evidence of progressively younger sediments as they approach mid-ocean ridges. These sediment cores contain layers of different types of sediments that have been deposited over time.

The layers of sediment get younger as they approach the mid-ocean ridges, which confirms the process of seafloor spreading.
