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 the difference in the age of rocks near mid ocean ridges from those farther away from ridges?
Good question: Geologist use these methods to determine the ages of rocks. The absolute age of the rock and relative age of the rock. Now because the mid ocean ridges are place of divergent where plates move apart, the rock farther away from the ridges are older than the younger ones that are just form close to the ride. This is called relative dating. The absolute dating use Isotopes and radiometric dating meaning they have to have a hand sample to determine this. But I think the best method here for situation like this is the Relative ages of the rocks.
Does the fact that ocean crust is older the farther away it is from an ocean ridge support the theory of plate tectonics?
Yes, the fact that ocean crust is older the farther away it is from an ocean ridge supports the theory of plate tectonics. This is because new oceanic crust is formed at ocean ridges through the process of seafloor spreading, where molten rock rises and solidifies, pushing older crust away from the ridge. By observing the age of oceanic crust, scientists can trace the movement of tectonic plates and support the theory of plate tectonics.
How can you determine accurate ages of rock layers?
Stratigraphic position Age Dating techniques i.e. carbon etc Fossil Assemblage present in rock specimen
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.

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.
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

How did scientists find out that rocks farther away from the mid ocean ridges were older than those near it?
I don't know, that's why i came here. Obviously it didn't help.

How would you be able to tell which is older between two overlapping craters?
The older crater is typically the one that the other crater overlaps. By examining the relative position of the craters, scientists can determine the sequence of events - the crater that was already present before the overlapping one formed is the older one.
How do scientists use scientists use structural similarities to determine the evolutionary relationship?
Scientists use structural similarities, such as homologous structures and similar biochemical pathways, to determine evolutionary relationships. These similarities suggest a common ancestry and can help scientists infer how different species are related to each other. By comparing the presence and arrangement of these structures among different species, scientists can construct evolutionary trees to understand the history of life on Earth.
What can scientists discover by counting the number of craters on a surface?
Scientists can discover the relative age of two objects by counting the number of craters on their surfaces. The longer an object has been in space, the more craters it should have. Comparing the number of craters on two objects in space will determine which is older.
What law do scientists apply to determine relative ages of rocks when the find faults or intrusions?
Scientists use the principle of cross-cutting relationships to determine the relative ages of rocks when they find faults or intrusions. This principle states that the rock being cut must be older than the geological event cutting through it (like a fault or intrusion). By analyzing the sequence of events and their relative ages, scientists can piece together the geological history of a region.
How does sediment that is closer to a mid ocean ridge compare to sediment that is farther away?
it is older
