Less than 200 Million years old.
The oldest rocks are actually on land but in the ocean crust they would be the rocks closest to land. The mid-ocean ridge forms new rocks. They are usually located in the middle of the ocean.
The oldest rocks are typically found on land, as they have not been eroded away by oceanic processes. The oldest known rocks on Earth are found in Western Australia and are estimated to be around 4 billion years old.
The oldest rocks on the ocean floor would be those at the colliding edge of the plate boundary.Answer 2: The oldest of all oceanic rocks are on the Asian side of the pacific plate.
The oldest rock on the ocean floor can be found in the central parts of the ocean basins, particularly in regions known as abyssal plains. These rocks are generally around 200 million years old or older.
The oldest rocks on the continents would be much older than the rocks on the sea floor because the rocks on the continents are not being removed unlike the rocks on the sea floor that are made by the mid-ocean ridge are being removed by deep ocean trenches. this prossess that is occuring on the sea floor is called sea floor spreading. evidence of this is the Pacific ocean shrinking and the Atlantic ocean growing.
Nope. The oldest rocks are located on continents, usually away from the ocean. The mid-ocean ridges are, in fact, home of some of the youngest rocks. The reason for this is what is called sea-floor spreading. Mid-ocean ridges form at places where oceanic plates diverge, or move apart. As this happens, magma rises from within the Earth to fill the gap. The magma cools and solidifies, creating new seafloor. This process continues as the plates continue to spread apart.
The oldest rock's found on the moon are 4.0 billion years old.
In 1990, after 20 years of searching, geologists found the oldest oceanic rocks by drilling into the seafloor of the western Pacific. These rocks turned out to be about 200 million years old, only about 4% of the Earth's age.
No, the oldest rocks on Earth are not located in the Grand Canyon. The oldest rocks found on Earth are estimated to be over 4 billion years old and are typically found in locations such as Canada, Australia, and Africa.
No. Oceanic crust is recycled into the mantle through a process called subduction and new ocean floor is formed at mid-ocean ridges. None of the ocean floor is more than about 180 million years old. Some rocks on the continents are billions of years old.
they are in Iceland and are 4 billion years old
The oldest rock are up to 125 million years old.
