Where are the youngest rocks on the ocean floor typically found?
fault line
How did scientists find out that rocks farther away from the mid-ocean ridges were older than those near it?
Radiometric dating. They sampled the basaltic rocks of the sea floor, and analyzed their radioisotope ratios. This produces an accurate age. They also measured the paleomagnetic striping on the sea floor, and have matched sea floor rock ages to those on land. The radioisotope dates are in good agreement with the measured rates of sea floor spreading. Currently, for example, the Atlantic Ocean is opening by a few inches per year. The Pacific sea floor is spreading even faster, but it is sucked beneath the American and Asian plate margins faster yet, creating orogeny (mountain building) particularly along the western edge of the north and south American plates. In other words, the Pacific Ocean is shrinking, even though its floor spreads a bit faster. This is expected to continue for another half billion years or so, and then reverse, in what is known as the Wilson cycle.
What rocks are used to make floor tiles?
Common rocks used to make floor tiles include granite, marble, slate, and limestone. These rocks are cut into tiles of various sizes and thicknesses to be used as flooring material. Each type of rock offers different colors, patterns, and durability for floor tile applications.
Explain how scientists date sea-floor rocks?
bum
Are there sea shells on mountains?
Yes, some mountains were once underwater, so it's possible to find sea shells on mountains. These sea shells are typically found in areas where tectonic activities have pushed the sea floor up to form mountains.

Why is owl city so awesome?
Because Adam young rocks!
What is the ocean-floor evidence of pole reversals?
in magma and lava, there are magnetic minerals, called magnetite. When new magma reaches the surface, these minerals start to align with the existing magnetic 'field' around the earth, starting at the North pole, and ending at the South pole. once the magma cools, these minerals remain at this inclination. These rocks often form on the sea floor, where 2 plates are moving apart. Every 10,000 years (or so), the magnetic poles switch. So it would start at the south pole, to the north pole. This means the inclination of the minerals would swap in new magma. So as the sea continues to spread, there is a striped appearance on the sea floor, where the are symmetrical bands of alternating magnetically inclined rocks. Hope that helps :)

Where do tsunamis get their destructive power?
The source of energy is from movement of the sea floor or sediment on the sea floor. This movement displaces some water and so gives energy to the water.
How do sea stars avoid being washed out to sea?
they have special suckers attached to their points so that they can stay on rocks and such like.
Is Brazilian cherry a good hardwood floor?
Yes, it is a very good floor, but it does scratch easily. So if you have young kids or pets it would'nt be a good floor
At what boundary does sea-floor spreading occur?
Consider. In sea-floor spreading, the plates are spreading apart; in other words diverging. So sea-floor spreading occurs at a divergent boundary,
Why sulphide compounds generally found as rocks whereas chlorine compounds generally found in sea water?
Most of the metallic sulphides are insoluble in water so such compounds can not move with rivers to the sea so their maximum ratio is in rocks form.
Where does it live oysters?
in the sea at the bottom of the sea. Oysters live on the sea floor or attached to rocks. In salt water.

What is the grand bank why did Cabot find so many fish there?
because the sea floor is elavated.
