The age of rocks in the ocean crust depends on where the rocks are collected. Scientists collected rock samples from the sea floor. They found out that rock samples that were closer to mid-ocean ridges were younger than the samples farther away from the ridges. So pretty much you could get rocks that are thousands of years old to over millions of year old.

Rocks in ocean crust are as old as years.?
200 million
Rocks in ocean crust are as old as how many years?
200 million.
What is the type of crust formed on the ocean floor?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
Where on the ocean floor would you find old rocks?
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 accumulation of different sedimentary and metamorphic rocks combined with scraps of ocean crust is called .?
accretionary wedge

Where are the oldest rocks in the ocean crust?
The oldest rocks are actually on land but in the ocean crust they would be the rocks closest to land. The mid-ocean ridge forms new rocks. They are usually located in the middle of the ocean.
Which has the younger rock the continental crust or oceanic crust?
The youngest rocks will be formed from cooled magma. Therefore volcanism, either on the continental crust or oceanic crust will create the youngest rocks.
What is the type of crust formed on the ocean floor?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
Where are the oldest rocks located in the ocean crust?
The oldest rocks on the ocean floor would be those at the colliding edge of the plate boundary.Answer 2: The oldest of all oceanic rocks are on the Asian side of the pacific plate.
Are oceanic rocks billion years old?
No. Oceanic crust is recycled into the mantle through a process called subduction and new ocean floor is formed at mid-ocean ridges. None of the ocean floor is more than about 180 million years old. Some rocks on the continents are billions of years old.
Oceanic crust returns to the mantle at deep ocean trenches which are?
rocks
What is the ocean's crust made up of?
The oceanic crust is made up of mafic rocks which is rich in magnesium and iron. These rocks are also referred to as sima. The oceanic crust is similar to the continental crust, except it is thinner yet denser.
The youngest rocks on the ocean floor are located?
The youngest part of the ocean floor is found at conservative plate boundaries where oceanic crust is pulled apart and magma rises from the mantle to form new oceanic crust.
