Why is the oldest seafloor crust found farthest from a mid-ocean ridge?
because the older crust is pushed out by the newer crust that is forming
In earths crust What type of rock is found under the oceans?
Oceanic crust, new oceanic crust is produced by seafloor spreading.
Are the oldest rocks of the oceanic crust found in deep ocean trenches far away from active mid-ocean ridges?
That is normally where they would be found; farthest away from the point at which they were initially formed.
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.
What tectonic plate is primarily comprised of seafloor crust?
Divergent plate boundaries are often found on the ocean floorâ??s crust. These are the type of tectonic plates that produce volcanoes and rifts.
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.
Some of the oldest continental crust on Earth lies in?
The oldest crust on earth can be found in Australia and parts of Canada. It ranges in age from 3. 7 to 4. 28 billion years old.
Why is the oldest rock at the bottom of the ocean?
The oldest rock is found in the continental crust. The youngest rock is found in the oceanic crust. This is because the ocean floor is recycled every 160 million years or so in the process of plate tectonics.
Where do you find the oldest crust on the planet?
Not reallys sure of this question but will give it a try. New crust are born in divergent boundary in mid atlantic ridges Old places are destroyed in subductions zones The oldest might be found in shields (Canadian Shields) or where old crust are accreted to new ones
Where is the oldest and newest crust on the earth?
Geothermal activity has revealed new characteristics of Earth's crust near Lake Myvatn, Iceland. In places like Iceland, new research has shown volcanoes and hot springs forming as the result of activity between the crust and the mantle.
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.
