How did scientists discover that rocks get older from the mid ocean ridge?

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?
I don't believe that is possible to figure 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
How scientist discover that rocks farther away from the mid ocean ridge were older than those near it?
By determing the age of rock samples obtained by drilling in the sea floor!:)
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 do rocks along the central valley of the mid ocean ridge provide evidence for sea floor spreading?
because the scientists found that the farther the rocks the older the rocks were. so the youngest rocks were found near the mid-ocean ridge. this showed that sea-floor spreading took place. +++ The primary evidence is "magnetic striping": remnant magnetising by the Earth's magnetic field of the iron compounds in the basalt forming the ocean floor. The magnetic traces are parallel to the spreading-ridges, and their polarity reflect the field's periodic reversal. The further from the ridge, the older the stripes. The rock is imprinted with the magnetism as it cools below a certain point in being eruped along the ridge.

i never know
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.

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
What did scientists learn when they mapped the ocean floor in the 1800s?
there is a mid-atlantic ridge
What evidence proved the ocean floor was moving?
oceanic crust that was farther away from a mid-ocean ridge was older than crust closer to the ridge
