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.
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.
It helps them determine the frequency of shifts in the magnetic orientation of the Earth, and initially led to the confirmation of seafloor spreading at the mid-ocean ridges.
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.
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
Sorry for this late response,but basically, as the plates move farther away from the mid-ocean ridges, the older it gets..! Hope this helps! ^^
Scientists discovered that the rocks that were found farther away from the ridge the sample was taken from, the older the rocks were. The most recent rocks were always in the center of the ridges. This showed that sea-floor spreading really has taken place.
occlusal table means the area bounded by the cusp ridges and marginal 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.
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.
one of the unexpected discoveries was the presence of underwater mountians. scientists located mid-ocean ridges, the longest mountain chains in the world.
The ridges of the convolutions are gyri. The depressions are sulci or fissures.
According to scientists, the volcanic landforms at divergent ocean plate boundaries are known as oceanic ridges.
gyrus =ridges of the brains convolutions sulcrus=depressions of the brain
Loess blankets a broad area; sand dunes are mounds or ridges
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.
Trenches are formed by divergent plates, Whereas Ridges are formed by plate in collision.
The Koala has fingerprints that are so similar to the human fingerprint that it is almost impossible to tell them apart because of the pattern, shape and size of the ridges. Under the microscope, the ridges look exactly the same. The width of the ridge, the shape, general size and pattern is the same. The main difference is that the entire human palm and fingers are covered with ridges while the koala only has ridges… Read More
Does the fact that ocean crust is older the farther away it is from an ocean ridge support the theory of plate tectonics?
Yes. New ocean crust is being formed at the mid ocean ridges (MORs) resulting in the older crust being pushed farther away, moving the plates towards a subduction zone. MORs divide 2 plates.
Because i think milk teeth are whiter, And sometimes they have ridges when they come in.
The ridges of the Everest are very dangerous. Ridges is the word used in the sentence.
The Papillae are ridges in the stratum germinativum that arise from the dermis. These ridges create permanent ridges in the fingers, palms, and soles of the feet. These ridges or "friction ridges" help with grip and also cause "finger prints" which give us our own identity.
Zero.Dimes have ridges. Quarters have ridges. Pennies and Nickels don't.
Dermal ridges cause the overlying epidermis to form epidermal ridges. Collectively these ridges are called friction ridges.
Genetic factors determine the structure of an individualâ??s fingerprint, and this entails the pattern of ridges and valleys. The micro-environment of the fetus determines the position of future skin indentations.
There is 118 ridges on a dime.
The ridges in cerebrum are called
The ridges are for compressive strenght
I counted 119 ridges.
I think just a oceanic ridges
The ridges around the edge of a dime is called reeding or milling. There are 118 ridges.
The important difference is that Moraine is a mass of debris carried by glaciers which forms ridges and mounds when deposited. Scree is just an accumulation of weathered mass at the foot of a cliff or on a hillside forming a sloping heap
The ridges are to give you traction - try running in socks to see what it's like without the ridges.
where are ocean ridges located at

Please explain 'ridges' .
The Production Budget for The Ridges was $17,300.
Stanley Ridges died in 1951.
Stanley Ridges was born in 1890.

Divergent boundaries form ocean ridges.
"Corduroy" is a thick cloth with ridges.

Yes - the ridges are called milling, or reeding.
An American quarter has 119 ridges. Believe it or not, a dime has 118 ridges- that's only one more ridge!
There are 119 ridges - aka "reeds" - on a US quarter; its Canadian counterpart has 130 ridges. Additional snippet A US dime has 118 ridges - that's only one fewer ridge than the quarter.
It is true that mid-ocean ridges are underwater mountain ranges. These ridges are long, seismically active submarine ridges associated with seafloor spreading.
Type your answer here... Trenches are man made recess on earth for use in the warfare or some other reason.Ridges are naturally formed in the mountanious regions.
Mid- ocean ridges are also referred to as underwater mountain ridges. This is because they are formed the same way.
The brain has a convoluted shape; the ridges are convolutions.
