Old ocean floor is destroyed and absorbed by the Earth and remelted beneath what?
Old ocean floor is destroyed and absorbed by the Earth at subduction zones, where tectonic plates collide and one plate is forced beneath the other. The remelting occurs beneath volcanic arcs, where the subducted crust melts and rises to the surface as magma, leading to the formation of new crust.
Why was the discovery of no rocks older than 2billion years old on the ocean floor so important?
It is an indication that the ocean floor is moving, being created by rifting and destroyed by subduction, thus providing evidence of plate tectonics and continental drift.
Is the floor near the mid ocean old?
No. The newest ocean floor is at the mid-ocean ridge.
What is the floor of the ocean called?
The floor of the ocean is called the seabed or ocean floor. It is made up of different features such as abyssal plains, trenches, ridges, and volcanoes.
Is the ocean floor a good place for fossils to form?
A lot of shells of marine organisms wind up on the ocean floor. Bones do not last on the ocean floor, they get eaten. But shells can last.

What would happen if old ocean floor were not destroyed in deep trenches?
If old ocean floor were not destroyed in deep trenches, it would continue to accumulate over time and result in the expansion of the ocean basins. This could potentially lead to changes in ocean circulation patterns and alter the balance of heat and nutrients in the oceans, which would impact marine ecosystems.

Sea floor is destroyed in which plate boundry?
The sea floor is destroyed in subduction zones, where one tectonic plate is pushed beneath another. This process is responsible for the destruction of oceanic crust and the formation of deep ocean trenches.
What is the topography of the ocean floor?

Is ocean floor smooth?
The ocean floor is not smooth.The ocean floor is made up of rocks, ledges and ditches.

What are the plants and animals that live on the ocean floor?

Is the floor near the mid ocean old?
No. The newest ocean floor is at the mid-ocean ridge.
