How did scientists find out that rocks farther away from the mid-ocean ridges were older than those near it?
Scientists found out that rocks farther away from mid-ocean ridges were older through the process of radiometric dating. By analyzing the radioactive isotopes within the rocks, scientists can determine their age. The rocks closer to the mid-ocean ridges are younger because they are continually being formed at the spreading centers, while the rocks farther away are older as they have moved away from the ridge over time. This process of seafloor spreading and the age of rocks on the ocean floor provide evidence for plate tectonics.

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 the ages of the rocks on the seafloor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
How did research from the Glomar Challenger help scientists support the theory of seafloor spreading?
Drill cores from the ocean floor were dated and found to be very young compared to the age of the earth. This means the crust had to be formed recently, which can be explained by creation of crust at a spreading center.
How does seafloor spreading support continental drift?
Seafloor spreading occurs at mid-ocean ridges where new oceanic crust is formed and spreads away from the ridge. This process provides evidence for continental drift as it shows that the oceanic crust is younger near the ridges and gets progressively older farther away. This supports the idea that continents were once connected and have since moved apart.
Isochron maps indicate what about the seafloor of the ocean crust?
Isochron maps indicate the age of the seafloor on the ocean crust. They show patterns of different ages of the oceanic crust moving away from mid-ocean ridges, where new crust is being formed. Younger crust is found closer to the ridges, while older crust is found farther away.
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.
What happens the age of rock with distance from the mid ocean ridges?
The age of rock increases with distance from mid-ocean ridges. At the ridges, new oceanic crust is formed through volcanic activity, which is young. As the crust moves away from the ridges, it cools and becomes older. This process is known as 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.

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 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 do the ages of the rocks on the seafloor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
What is the relationship between distance from the ridges and age of the crust?
At the oceanic ridges the age of igneous basalt rocks is approximately zero (as that is where they formed) and the rocks get older the farther away. The ages of sedimentary and metamorphic rocks does not correlate reliably with distance from the oceanic ridges like the ages of igneous rocks, because they can form anywhere not mainly at oceanic ridges. Igneous granite rocks are generally formed around continental volcanos not oceanic ridges.
How do the ages of the rocks on the ocean floor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
