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.
A non-solid. The particles are really spread out in a gas, and less spread-out in a liquid.
I really really really really really really really do not know
Something really really big
cold in my opinion
Do rephrase how you practice really makes perfect.
people here are stupid , really the answer is not hi

Sea floor Spreading! -Lucy laboy Thanks that really helped alot.
SCAM....no, you do not get free samples

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
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.
Not really, they are totally different techniques, but at least you won't start from basics.
It is spreading a lot in Europe, the USA and Australia, but really, it is spreading practically everywhere
A really big blace dick
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 :)
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.
