When scientist drilled into the ocean floor taking rock samples what did they discover about the age of the rocks?

oldest at the bottom youngest on top. Its the law of superposition. They also found that the age of rocks increases with increased distance from mid-ocean-ridges.


What three pieces of evidence for Wegener's theory came from the sea floor?

seafloor spreading, age of the sea floor and ocean trenches.


What discovery did scientist make when comparing the age of the sea floor to that of the continents?

The scientists realized that the continents were much older, leading them onto the theory of Sea Floor Spreading!


How did research from the Glomar Challenger help scientist support the theory of seafloor spreading?

Drill cores from the ocean floor were dated and found to be very young compared to the age of the earth. This means the crust had to be formed recently, which can be explained by creation of crust at a spreading center.


How would the age of the oldest rocks on the continents compare with the age of the oldest rocks on the seafloor if the rock on the continents is continually formed but not removed?

The oldest rocks on the continents would be much older than the rocks on the sea floor because the rocks on the continents are not being removed unlike the rocks on the sea floor that are made by the mid-ocean ridge are being removed by deep ocean trenches. this prossess that is occuring on the sea floor is called sea floor spreading. evidence of this is the Pacific ocean shrinking and the Atlantic ocean growing.


Why is the rock farther from the ocean ridge is older than the rock near the mid ocean ridge?

By determining the age of rock samples obtained by drilling on the sea floor.


The age of a ocean floor is greatest in subduction zone or?

subducting slab begins to descend beneath another lithospheric slab. Trenches are generally parallel to a volcanic island arc, and about 200 km (120 mi) from a volcanic arc. hence the age of ocean floor is usually greatest in subduction zones


How does the age of seafloor sediments change the increasing distance from the oceans ridge?

age increases


What are three types of evidence provided support for the theory of sea-floor spreading?

Magnetic striping: Patterns of alternating magnetic polarity in the rock of the ocean floor provide evidence of the seafloor moving away from mid-ocean ridges. Age of the oceanic crust: Younger rocks are found nearer to mid-ocean ridges, supporting the idea of continuous seafloor creation. Ocean drilling samples: Rock samples from the ocean floor show consistent patterns of increasing age with distance from mid-ocean ridges, supporting the theory of seafloor spreading.


How do scientists use to determine the age of a rock on the ocean floor?

Scientists use a method called radiometric dating to determine the age of rocks on the ocean floor. This technique involves measuring the proportions of certain radioactive isotopes and their decay products within the rock to calculate how long it has been since the rock formed. By analyzing these ratios, scientists can estimate the age of the rock.
