What else can I help you with?
Where would I find the oldest rock on the ocean floor?
The oldest rock on the ocean floor can be found in the central parts of the ocean basins, particularly in regions known as abyssal plains. These rocks are generally around 200 million years old or older.
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.
Where would you expect to find oldest rock on the ocean floor?
Somewhere at the bottom of the Marianas Trench you would find the oldest rock of the oceanic crust. Somewhere else, however, there are older rocks on the ocean floor--those deposited by icebergs that have broken off of glaciers. Those erratic rocks could be much older than the oldest oceanic crust.
Is there clay at the bottom of the ocean?
Yes, there is clay at the bottom of the ocean. Clay particles are tiny mineral particles that settle on the ocean floor over time. They can come from sources like erosion of rocks on land or volcanic activity.
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 will you find on the ocean floor?
sand,rocks
What kinds of rocks are in the ocean?
The ocean floor is mainly basalt. Closer to the poles you would occassionally find a glacial erratic, dropped from a melting iceberg.

What might you find at the mid ocean ridge?
at the mid-ocean ridge you can find the youngest oceanic plate and a divergent boundary.

Fossils found in younger rocks?
The youngest rocks would be igneous, those created by cooling magma. Impossible to find a fossil there.
What do scientsit find when they study the ocean floor?
sand
How does carbon from the ocean get into shells that settle on the ocean floor?
Read a book and u will find out
If you could collect a sample of rock from the Mid-Atlantic Ridge where would you look to find the youngest rocks?
You would want to look for rocks at the center of the Mid-Atlantic Ridge, where new oceanic crust is forming through seafloor spreading. The rocks found closest to the ridge axis are typically the youngest, as they have most recently solidified from magma.
Where do you find oil?
You normally find oil in the ground or under the ocean floor.
