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.

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.
What is the function of the ridges of your ear?
The ridges of the ear, known as the auricular or cartilage ridges, serve several functions. They help to funnel sound waves into the ear canal, enhancing auditory perception. Additionally, the unique shape of these ridges aids in sound localization, allowing us to determine the direction from which sounds are coming. The ridges also contribute to the overall structure and stability of the ear.
What causes the growth ridges on the shells of bivalves?
Growth ridges on the shells of bivalves are caused by seasonal changes in their growth rate. During periods of slow growth, the ridges become more pronounced, while faster growth results in smoother areas on the shell. These ridges are a natural part of the shell growth process and can be used to determine the age of the bivalve.
How old are rocks in ocean crust?
The age of rocks in the ocean crust depends on where the rocks are collected. Scientists collected rock samples from the sea floor. They found out that rock samples that were closer to mid-ocean ridges were younger than the samples farther away from the ridges. So pretty much you could get rocks that are thousands of years old to over millions of year old.
What is it when plates move farther and farther apart?
When plates move farther and farther apart, this is known as seafloor spreading. It occurs at mid-ocean ridges where new oceanic crust is formed as plates diverge. This process is driven by convection currents in the Earth's mantle.
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 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.
What is difference between ocean ridges and rises?
Ridges and Rises are uplifts in oceanic crust caused by volcanic eruption in oceans, the difference between a ridge and a rise is of rift valleys, ridges have long valleys and rises do not have any valleys
Difference between occlusal outline and occlusal table of the teeth?
occlusal table means the area bounded by the cusp ridges and marginal ridges
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.
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.
What motion of the sea floor is responsible for the formation of the mid Atlantic ridges rift valley?
According to scientists, the process associated with seafloor spreading is responsible for the formation of the mid Atlantic ridges rift valley.
When did scientists first discover the mid-Atlantic ridges?
The ridge was discovered during the expedition of HMS Challenger in 1872. A team of scientists on board, led by Charles Wyville Thompson.

What did the precision depth recorder help scientists discover?
one of the unexpected discoveries was the presence of underwater mountians. scientists located mid-ocean ridges, the longest mountain chains in the world.
What is the difference between wavy and ripple chips?
Wavy chips have ridges that are more pronounced and uniform, while ripple chips have irregular, deeper ridges that create a more textured surface.
