The oldest oceanic crust is generally found at the largest distance from the spreading centre where it was generated. the best place to go at the moment would be the Pacific Ocean south east of Japan, where there is Jurassic ocean crust preserved. Oceanic crust of the same age can be found East of the United States of America and west of Africa as well but there one finds much less because of slower spreading rates.
These rocks are usually buried by hundreds of meters of sediments and are thus mostly not directly accessible. Very old rocks can be found on the ocean floor, when icebergs carry gravel and stones derived from old continental crust (like large parts of Skandinavia) onto the ocean and drop them as they melt (drop stones).

What would you expect to find if you measured the temperatures of rocks on the ocean floor at various distances from a mid-ocean ridge?
If one was measuring the temperatures of rocks on the seafloor, the hottest rocks would be located nearest to a mid ocean ridge. This is the location where the hot magma from the asthenosphere rises and is situated on either side of the ridge. The farther away the seafloor is from the central area of heat, the colder it is. This pattern is identical on both sides of a mid ocean ridge. However, if rocks are located near subduction zones or hot spots, they too would be hotter than the majority of the seafloor.
What geologic features would you expect to find on the ocean floor near the volcano and earthquake areas on your map?
oceanic trenches
Where do you find chemoautotrophs?
On rocks in the north pole and in the bottem of the ocean in cold water
How are sedimentary rocks formed and where would you find them?
They are formed over millions of years of sand being packed down by the ocean.....And you can find them where oceans are located or were located like hoodoos and coulies.
What type of rocks would you expect to find around a volcano crater?
You would find extrusive igneous rocks. Beyond that it depends on the volcano.
Where can you find the youngest rocks on the ocean floor?
you can find the youngest rocks on the top of the ocean floor.
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.
Where would you expect to find the oldest 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.

What regions would you expect to find the largest amounts of dissolved oxygen in the ocean floor?
in the deep oceon floor
In which sea would you find western Samoa?
pacific ocean st pats rocks
Where would be a good place to find very young rocks?
At the Mid-ocean ridge, because those rocks will have just been produced by the diverging boundary.
What do scientsit find when they study the ocean floor?
sand
Where would you find abyssal hills?
Abyssal hills are small hills that rise from the abyssal plain, which is the floor of the ocean.
