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 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.
What is the relationship between the age of rocks on the ocean floor and the distance from the Mid-Atlantic ridge?
The farther away the rocks are, the older they are. When the lava bubbles up from the ridge, the tectonic plates move outward. As the process repeates itself and new lava comes up, the rocks are pushed farther and father away. As a result, the closest rocks are the newest, and the farthest rocks are the oldest!
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.
What happens to the ocean floor the farther the oceanic lithosphere is from a mid ocean ridge?
As the oceanic lithosphere moves away from a mid-ocean ridge, it cools and thickens. This process causes the ocean floor to become older and denser, resulting in its gradual subsidence. The farther it gets from the ridge, the deeper the ocean floor becomes due to the increased thickness and weight of the lithosphere.
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 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 did scientist discover that rocks farther away from the mid ocean ridge were older that those near it?
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.
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 determine that the age of rocks farther from the mid-ocean ridge were older?
thye pulled rocks from a drill and studied them obviously
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.
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 does Benjamin Franklin discover as he gets older?
Pemory last!
How does sediment that is closer to a mid ocean ridge compare to sediment that is farther away?
it is older
Is Older oceanic crust found at the center of mid-ocean ridge?
No farther away
Does the vegetarian diet change as you get older?
Yes it does. You will discover more foods to eat.
