Which are younger old seafloor rocks or old continental rocks?
Old sea floor rocks are much younger than old continental rocks! This is because the oceanic lithospheric plate forming the seafloor tends to be recycled at places known as subduction zones where it is forced below less dense (commonly continental) lithosphere. As such the oldest continental rocks tend to be 2-3 billion years old whereas oceanic crust neve tends to be more than a few hundred million years old.
The oldest rocks on the seafloor are much younger than the oldest rocks on the continents?
The rocks on the seafloor are generally less than 200 million years old due to the process of seafloor spreading and subduction, which recycles old rocks. In contrast, some rocks on the continents can be over 4 billion years old, dating back to the formation of Earth's crust. This difference in age is attributed to the dynamic nature of plate tectonics.
Are oceanic rocks billion years old?
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.
Rocks in continental crust are as old as years.?
Rocks in continental crust can be as old as about 4 billion years. This is because the continental crust is made up of a mixture of ancient rocks that have been around since the Earth's early history. By studying these rocks, scientists can learn more about the planet's evolution and geological processes.
