What else can I help you with?
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.
Where can you find the youngest rocks on the ocean floor?
The youngest rocks on the ocean floor are typically found along mid-ocean ridges. These areas are where new oceanic crust is formed through volcanic activity and the process of seafloor spreading. As the magma cools and solidifies, it creates new rocks that are relatively young compared to rocks found in other parts of the ocean floor.
Where would you find the oldest crust?
You would find the oldest crust on Earth in certain parts of continental areas, such as the Canadian Shield or parts of Western Australia. These areas contain rocks that are over 3 billion years old, making them some of the oldest crust on the planet.
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.
What did scientist find at the ocean floor?
Scientists have discovered a variety of things at the ocean floor, including new species of marine life, underwater volcanoes, hydrothermal vents, and deep-sea trenches. They have also found evidence of ancient civilizations, shipwrecks, and valuable resources like oil and minerals. Exploration of the ocean floor continues to reveal new and exciting discoveries about our planet's underwater world.

What happens when the plate motions compresses part the crust?
where do you expect to find the oldest rock on the ocean floor
What feature on the ocean floor would you most likely find the oldest seafloor?
in a subduction trench, because of Harry Hess' theory of sea floor spreading. Meaning that the rock is formed new at the mid-ocean ridge, and moved out towards the coasts into a subduction zone years and years later.

Where in relation to a mid ocean ridge would you find the oldest oceanic lithosphere?
the bottom
What regions would you expect to find the largest amounts of dissolved oxygen in the ocean floor?
in the deep oceon floor
Where would you expect to find the oldest rock on the sea floor?
At the greatest distance from a mid oceanic spreading centre.
Where would you find the oldest rock in a maid ocean ridge system and why?
The oldest rock in a mid-ocean ridge system is typically found furthest from the ridge axis on the ocean floor. This is because as tectonic plates diverge at the ridge, magma rises and solidifies to form new oceanic crust. Over time, the older crust moves away from the ridge due to seafloor spreading, making it progressively older the farther you go from the ridge. Thus, the oldest rocks are located at the outer edges of the mid-ocean ridge system.
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 will you find on the ocean floor?
sand,rocks
Where would you find abyssal hills?
Abyssal hills are small hills that rise from the abyssal plain, which is the floor of the ocean.
