Answer:
Cores taken near the oceanic ridges show the age and thickness of the sediment increases as you move away from the ridge. This supports seafloor spreading because it indicates the

Explanation:
- Seafloor spreading is such a process which takes place when a volcano occurs. Due to which a new oceanic crust is formed which gradually move away from the ridge.
- Cores taken near the oceanic ridges show the age and thickness of the sediment increases as you move away from the ridge. The younger crust nearest the ridges has not been around long enough to accumulate the same thickness of sediment that's why the the sections of crust that are further from the ridges have longer time to have more thickness and age.
