Around 200 million years of age.
The oldest rock's found on the moon are 4.0 billion years old.
The oldest rocks in North America are found in Minnesota. The oldest of these rocks age to 3.6 billion years old.
The ocean is 4 billion yars old, however due to subduction, the oldest sediment found in the ocean's floor is 180 million years old.
lunar rocks may be fractured in the lab throw off sparks
The oldest rocks on the ocean floor would be those at the colliding edge of the plate boundary.Answer 2: The oldest of all oceanic rocks are on the Asian side of the pacific plate.
Rocks can be found almost anywhere, sandstone can be found in beaches, granite is mostly found in New York city. I hear there might be some igneous rocks in central park.
The sea floor is older than 200 million years. It has been recycled by plate tectonics. Very old rocks have survived.
Among other things, rocks have been found that are over 4 billion years old. The age of such rocks is determined by radioactive dating. Note that this is not "a" method, but perhaps 40 different methods (depending on the isotopes involved), which complement one another.The exact age of the Earth is harder to determine exactly; but basically, it must be at least as old as the oldest rocks found.
About 4.5 billion years old - calculated by the radioactive dating of the oldest rocks found AND the dating of even older meteorites.
It is believed that old rocks are rare on ocean floors bevause the floor has manny remains and we are not unable to reach them
they are in Iceland and are 4 billion years old
Old sea floor rocks are much younger than old continental rocks! This is because the oceanic lithospheric plate forming the seafloor tends to be recycled at places known as subduction zones where it is forced below less dense (commonly continental) lithosphere. As such the oldest continental rocks tend to be 2-3 billion years old whereas oceanic crust neve tends to be more than a few hundred million years old.
