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 would you expect to find oldest rock 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.
How does the age of the oldest continental crust compare to the age of the oldest ocean crust?
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
How does the age of the oldest continental crust compare to the age of the oldest ocean crust-?
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.

Which planet has iron oxide in its crust?
Mars
What can you find on the crust of the Earth?
All of the Earth's surface features are on the crust of our planet. The oceans, the mountains, the plains and deserts and forests, and all lakes and rivers are on the crust of the planet on which we live.

What happens when the plate motions compresses part the crust?
where do you expect to find the oldest rock on the ocean floor
What happens if planet has no crust?
Gas planets such as Jupiter have no crust as they are made primary of hydrogen and helium rather than rock. A terrestrial planet without a crust would not be all that different from a planet with a crust as the difference between the crust and the mantle of a planet has more to do with chemical composition than anything else.

What is the difference from a gas planet and a rock planet?
The existence or not of an outer rocky crust above a rocky mantle. A gas planet has no crust.
