Where are the elder parts of the ocean floor located?
The older parts of the ocean floor are typically found farther away from mid-ocean ridges, where new oceanic crust is formed. As the crust moves away from the ridges, it cools and becomes older. This results in the oldest oceanic crust being located near the edges of ocean basins.
How old is the oceanic crust?
It varies, but the oldest part is 180 million years old
What are convertgent boundaries?
A conversion boundary is a place where 2 tectonic plates are mving toward each other. There are 3 types of convergent boundaries OCEANIC CRUST-OCEANIC CRUST OCEANIC CRUST-CONTINENTAL CRUST CONTINENTAL CRUST-CONTINENTAL CRUST They are classified according to their 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.
How does the age of the oldest continental crust compare to the age of 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.
Where would you drill to recover samples of the oldest basaltic oceanic crust which is Jurassic age?
To recover samples of the oldest basaltic oceanic crust, which is Jurassic in age, you would need to drill in regions where the crust is still preserved. The best places to do this would be in certain portions of the western Pacific Ocean, such as the western Pacific Basin or the western regions of the Northwest Pacific Ocean, where Jurassic-aged oceanic crust is known to exist. Conducting deep-sea drilling operations in these areas can help recover samples for study.
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.
What were the goals of the deep sea drilling project?
To investigate the evolution of ocean basins by core drilling of ocean sediments and underlying oceanic 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.
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.
Where are the elder parts of the ocean floor located?
The older parts of the ocean floor are typically found farther away from mid-ocean ridges, where new oceanic crust is formed. As the crust moves away from the ridges, it cools and becomes older. This results in the oldest oceanic crust being located near the edges of ocean basins.

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 old is the oceanic crust?
It varies, but the oldest part is 180 million years old
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.
Where are the oldest rocks located in the ocean crust?
The oldest rocks in the ocean crust are typically found near mid-ocean ridges, which are tectonic plate boundaries where new crust is formed. The oldest oceanic crust is estimated to be around 200 million years old.

What is the age of the oldest ocean?
The oldest oceanic crust is in the west Pacific and north-west Atlantic. They are about 180 to 200 million years old.
