Does the farther from a mid-ocean ridge a rock is a sample is taken the younger the rock is?
No, the farther from a mid-ocean ridge a rock sample is taken, the older the rock generally is. Mid-ocean ridges are sites of seafloor spreading, where new oceanic crust is formed as magma rises and cools. As tectonic plates move away from the ridge, the rocks gradually age, making those farther from the ridge older than those closer to it.
How did the discovery about seafloor spreading modify the theory of Continental drift?
Seafloor spreading explained WHY and how Continental Drift occurs. How can lands be 'moving' without a catastrophic or even noticeable change--- seafloor spreading accounts for these small changes. It identifies where the actual changes take place (even if we cannot identify the exact spots where spreading occurs). We can better estimate how much the "spreading" equates to observable/measurable changes of continents, specifically how fast (slowly) continents are moving closer or further apart. Seafloor spreading explains other phenomena, too, like the expulsion of methane gas pockets at the ocean floor which are suspected to interfere with flotation of ships and possibly the downing of airplanes that pass over where methane is released when methane gas disrupts the air above the water. Seafloor spreading also gives clues as to how mountains and valleys form underwater and on land.
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.
When Seafloor spreading is occurring at the boundary between the?
When seafloor spreading occurs at the boundary between tectonic plates, it typically takes place at mid-ocean ridges, where two oceanic plates diverge. As the plates pull apart, magma rises from the mantle to fill the gap, solidifying to form new oceanic crust. This process not only creates new seafloor but also contributes to the age progression of the ocean floor, with younger rocks located closer to the ridge and older rocks further away. Seafloor spreading is a key mechanism of plate tectonics and plays a significant role in shaping ocean basins.
What evidence is there to support the theory of sea floor spreading?
the newer rock is closer to the middle n th older ones spread along the sides
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.
How do the ages of rock 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.

How does the age of rocks in the seafloor provide evidence of seafloor spreading?
The age of rocks gets progressively younger as you move away from the mid-ocean ridges, where seafloor spreading occurs. This supports the theory of seafloor spreading, as new crust is being formed at the ridges and then moves away from them over time. This process leaves a record of older rocks further from the ridges and younger rocks closer to them.
How does sediment that is closer to a mid-ocean ridge compare to sediment that is farther away?
Sediment closer to a mid-ocean ridge is typically younger, thinner, and composed of more volcanic material compared to sediment farther away. This is because the ridge is a site of active seafloor spreading where new oceanic crust is formed, leading to a higher rate of sedimentation near the ridge.

How does evidence that rocks farther from a ridge are older than rocks closer to the ridge support the idea of sea floor spreading?
The evidence that rocks farther from a ridge are older than rocks closer to the ridge supports the idea of sea floor spreading because it aligns with the concept of a divergent boundary where new oceanic crust is continuously formed at the ridge and gradually moves away from the ridge over time. This process allows for the creation of age gradients in the oceanic crust, with the youngest rocks found near the ridge and progressively older rocks located farther away.
Do you have evidence of seafloor spreading?
I don't have evidence, but oceanographers have evidence. In mid ocean ridges, more and more molten rocks come up from the surface and cool down. As a result, the rocks already there get pushed away. We did find molten rock coming up from the mantle. Also, when scientist carbon dated the rocks on mid ocean ridges, they found that the farther you go outward, the older the rock. That's another sign. There's more but i can't think of it now. Hope this helps.
Is Axial rock younger than Oregon rock?
Yes, because Axial rock is closer to the mid-ocean ridge (which forms new rock due to seafloor spreading), than Oregon rock.
Explain how an isochron map of the ocean floor supports the theory of seafloor spreading?
An isochron is a line on a map that connects points that have the same age. An isochron map of the ocean floor supports the theory of seafloor spreading because it shows the older rock near the deep sea trenches and the younger rocks near ocean ridges.
