They discovered a pattern of reverse and normal polarity in the rock bodies of the ocean floor that indicated that oceanic crust was constantly being formed over time. Polarity shifts in the Earth had already been noted in continental crustal rock. With the advent of radiometric dating, core samples were taken and dated, confirming that the youngest rock is found at the ridge and rock age advances with distance from the ridge.

How did scientists discover that rocks farther away from the mid ocean ridge were older than the ones closer to the mid ocean ridge?
Scientists discovered that rocks farther away from the mid-ocean ridge were older than those closer to it through radiometric dating of the rocks. By analyzing the age of the rocks using isotopes with known half-lives, they were able to determine that the rocks get progressively older as you move away from the ridge due to the process of seafloor spreading.
How scientist discover that rocks farther away from the mid ocean ridge were older than those near it?
Scientists discovered that rocks farther away from the mid-ocean ridge were older than those near it through radiometric dating of the rocks. By measuring the age of the minerals within the rocks, they found that the farther rocks were older because they had been slowly moving away from the ridge as new crust formed at the ridge and pushed older crust farther out.
How did scientists determine that the age of rocks farther from the mid-ocean ridge were older?
thye pulled rocks from a drill and studied them obviously
Where would you find the oldest rock in a maid ocean ridge system and why?
The oldest rock in a mid-ocean ridge system is typically found furthest from the ridge axis on the ocean floor. This is because as tectonic plates diverge at the ridge, magma rises and solidifies to form new oceanic crust. Over time, the older crust moves away from the ridge due to seafloor spreading, making it progressively older the farther you go from the ridge. Thus, the oldest rocks are located at the outer edges of the mid-ocean ridge system.
How do the sediments on the ocean floor vary in relation to an ocean ridge?
Sediments become thicker away from the mid ocean ridge. This is because the oceanic crust away from the mid ocean ridge is older than the crust close to it, so sediment has had more time to accumulate.

How did scientists discover that rocks farther away from the mid-ocean ridge were older than those near it?
Scientists discovered that rocks farther away from the mid-ocean ridge were older through radiometric dating of the rocks. By analyzing the age of the minerals within the rocks, researchers found that the rocks closest to the ridge were younger, while those farther away were older, supporting the theory of seafloor spreading.
How do scientists explain older and younger rock placement on the ocean floor?
They measure how far away the rock is from the mid-ocean ridge. The farther, the older.

Sonar.
What evidence can prove that the ocean floor was moving?
Oceanic crust that was farther away from a mid-ocean ridge was older that crust closer to the ridge
Do Ocean sediments become younger or older away from midocean ridges?
Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
