What else can I help you with?
Where would I find the oldest rock on the ocean floor?
The oldest rock on the ocean floor can be found in the central parts of the ocean basins, particularly in regions known as abyssal plains. These rocks are generally around 200 million years old or older.
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.
Portion of the earth's crust that lies beneath the ocean floor?
The portion of Earth's crust that lies beneath the ocean floor is called oceanic crust. It is thinner and denser than continental crust, primarily composed of basaltic rocks, and formed at mid-ocean ridges through volcanic activity.
What is the part of earth where life exists and extends from the ocean floor to the lower atmosphere?
The biosphere is the part of Earth where life exists, extending from the ocean floor to the lower atmosphere. It includes all living organisms and their interactions with the environment.
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.
Why is the earth 4.6 billion years old but the oldest sea floor is only 180 millions years old?
Just as new sea floor forms at mid-ocean ridges, new sea floor is forced back into the mantle at abduction zones. The oldest seafloor is at east and west the edges of the Atlantic Ocean, dating to the breakup of Pangaea.
On the ocean floor where is the oldest rock?
The oldest rock in oceanic crust is that which is found the greatest distance from a mid-ocean-ridge.
Why are the oldest parts of the ocean floor no older than about 200 million years.?
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
In which layer of the Earth is the ocean floor?
The crust contains the ocean floor and also the continents on Earth.
What is the general depth of an ocean trench compared to the ocean floor?
True
Why are the oldest part of the ocean floor no older then about 200 million years old?
The ocean is 4 billion yars old, however due to subduction, the oldest sediment found in the ocean's floor is 180 million years old.
Where would I find the oldest rock on the ocean floor?
The oldest rock on the ocean floor can be found in the central parts of the ocean basins, particularly in regions known as abyssal plains. These rocks are generally around 200 million years old or older.
which layer of the earth forms ocean floor?
Ocean Crust.
What other ocean floor feature is formed by movement of Earth's plates?
what other ocean floor feature is fromed by movement of earth's plates
How old are the oldest of the ocean floor?
Less than 200 Million years old.
Why the crust is thinner than the ocean floor?
The Earth's crust is thinner than the ocean floor because the oceanic crust is formed at mid-ocean ridges where heat from the mantle creates new crust through volcanic activity. This process creates younger, hotter, and thinner crust in the ocean compared to the older and thicker continental crust.
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.
