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.

Rocks in continental crust are as old as years?
Rocks in continental crust can be as old as 4 billion years. This is because continental crust is much older than oceanic crust due to its formation through various geological processes over long periods of time. The oldest rocks found on Earth are typically located in the continental crust.
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.

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.
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.

Why is the oldest oceanic crust is considerably than the oldest continental rock?
Oceanic crust is more dense than continental crust. As a result, over time, continental crust is harder to "recycle". Rocks are recycled when they are subducted and remelted. Since continental crust is harder to subduct (it wants to keep floating), it is not recycled as much as oceanic crust, which is dense and will sink and remelt.
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.
What type of rock is the oldest continental crust made of?
Granite
Why is the oldest ocean crust only 150 million years old?
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
How does the age of the continental crust compare 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.
