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
The oldest crust on the planet can be found in the Pilbara region of Western Australia, where rocks dating back over 3.6 billion years have been discovered. These ancient rocks provide important insights into the Earth's early history and formation.

Where would you find the oldest crust?
You would find the oldest crust on Earth in certain parts of continental areas, such as the Canadian Shield or parts of Western Australia. These areas contain rocks that are over 3 billion years old, making them some of the oldest crust on the planet.
How does the age of the oldest continental crust compare to the age of the oldest ocean crust?
The age of the oldest continental crust is around 4 billion years old, while the age of the oldest ocean crust is about 200 million years old. Continental crust is generally older than oceanic crust due to the process of plate tectonics that continuously forms and recycles oceanic crust.
How does the age of the oldest continental crust compare to the age of the oldest ocean crust-?
The oldest continental crust is around 4 billion years old, while the oldest ocean crust is about 180 million years old. Continental crust is significantly older than oceanic crust due to differences in their formation and recycling processes.
How does the age of the oldest continental crust compared to the age of the oldest oceanic 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.
What physical characteristic of the bedrock responsible for oldest rock?
The physical characteristic of bedrock responsible for the oldest rock is its age. The oldest rock forms the foundation of the Earth's crust and is composed of minerals that have remained relatively unchanged for billions of years. This bedrock provides valuable information about the early history of our planet.

You would find the oldest crust on Earth in certain parts of continental areas, such as the Canadian Shield or parts of Western Australia. These areas contain rocks that are over 3 billion years old, making them some of the oldest crust on the planet.
Where would you expect to find the oldest rock on the oldest 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.
What happens when the plate motions compresses part the crust?

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.
How does the age of the oldest continental crust compared to the age of the oldest oceanic 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.
What can you find on the crust of the Earth?
On the Earth's crust, you can find various landforms such as mountains, valleys, plains, and plateaus. The crust also contains different types of rocks, minerals, soil, and bodies of water like rivers and lakes. Additionally, human settlements, vegetation, and wildlife exist on the Earth's crust.
How does the age of the oldest continental crust compare to the 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.
