Samples of sea floor basalt reveals that they do not exceed 200 million years of age. With the oldest continental rocks being in the neighborhood of 4 billion years of age, there's obviously some crust creation and destruction going on. Samples also indicate changing magnetic orientation in the magnetic minerals present in the basalt, with a matching orientation on the opposite side of the divergent boundary. This indicates that crust is being formed simultaneously on both sides of the mid-ocean ridge, over time, with the magnetic orientation matching the existing orientation at the time of its formation.
What else can I help you with?
What is the spreading out of a substance?
A non-solid. The particles are really spread out in a gas, and less spread-out in a liquid.
What happens to earths materials when they are exposed to sunlight?
I really really really really really really really do not know
What is ginormis?
Something really really big
Is it harder to survive in a really hot place or really cold place?
cold in my opinion
How do you rephrase does practice really makes perfect?
Do rephrase how you practice really makes perfect.
How did the seafloor drilling help scientist find evidence to support the seafloor-spreading hypothesis?
people here are stupid , really the answer is not hi

What term describes the process that creates new oceanic crust at mid-ocean ridges?
Sea floor Spreading! -Lucy laboy Thanks that really helped alot.
At freeflys do you really get free samples and coupons?
SCAM....no, you do not get free samples
How drilling samples show that sea floor spreading really has taken place?

Is the analysis of seafoor sediments evidence of sea-floor spreading?
Not really but sea floor sediments thickness increase with increased distance from spreading centers which is good evidence. Other evidence such as magnetic reversals, temperature, dating methods provide the best evidence of seafloor spreading
Explain how drilling samples provided evidence for sea floor spreading?
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.
Will water well drilling experience transfer to oil drilling?
Not really, they are totally different techniques, but at least you won't start from basics.
Where does Islam spread?
It is spreading a lot in Europe, the USA and Australia, but really, it is spreading practically everywhere
What is a pedestal drilling machine used for?
A really big blace dick
What is the difference between subduction and seafloor spreading?
Sea floor spreading is where new oceanic crust is formed through volcanic activity and then moves away from the ridge. Subduction is when one tectonic plate moves under another tectonic plate. Hope this helped :)
Does drilling and filling hurt?
To me it felt like someone was drilling and spraying cold water in my mouth. I was numb so I didn't really feel any pain.
