The entire ocean floor is recycled in roughly 160 million year cycles through the process of plate tectonics. Because continental plates do not subduct, the rock is much, much older, particularly in the continental interior.
Yes, the ocean floor has features such as mountains, valleys, ridges, and plains that are similar to those found on continents. These features are formed by processes like tectonic activity, volcanic eruptions, and erosion. Additionally, both the ocean floor and continents have ecosystems that support various marine and terrestrial organisms.

Wegner's hypothesis of continental drift was supported by evidence such as the jigsaw-like fit of continents, similarities in rock formations and geological structures across continents, and matching fossil evidence found on different continents. Additionally, the discovery of mid-ocean ridges and magnetic striping on the ocean floor provided further evidence for the movement of continents.
Sea floor spreading contributed to the breakup of Pangaea by creating new oceanic crust at mid-ocean ridges, causing the continents to drift apart. This process resulted in the formation of the Atlantic Ocean and the separation of the once-contiguous landmass Pangaea into multiple continents.
Evidence for the movement of Earth's continents includes the matching coastlines, similar rock formations and fossils found on different continents, and the distribution of certain plant and animal species across continents that were once connected. Additionally, the discovery of magnetic stripes on the ocean floor, along with the theory of plate tectonics, further support the idea that Earth's continents have moved over time.

Earth's crust is composed of the continents and the ocean floor.
Yes, the ocean floor has features such as mountains, valleys, ridges, and plains that are similar to those found on continents. These features are formed by processes like tectonic activity, volcanic eruptions, and erosion. Additionally, both the ocean floor and continents have ecosystems that support various marine and terrestrial organisms.
Tectonic Plates can't carry both ocean floor and continents on the same plate.
The continents and the ocean floor rest upon the plates.
No, mountains can also be found on the ocean floor. These underwater mountains are known as seamounts or guyots. They are formed by volcanic activity and can rise thousands of feet from the ocean floor.
blank are found on the ocean floor
They do touch the ocean floor. they're like a giant mound, and the beaches flow into the water.
The crust.
As it turns out, most of the ocean floor is basalt, and most of the continents are granite.
The oceanic crust of the Atlantic Ocean floor is attached to the continental crust of the continents around the ocean. So as the Atlantic's Ocean floor spreads, the continents along its edges also move. Over time, the whole ocean gets wider.
