What are three types of evidence provided support for the theory of sea-floor spreading?

Magnetic striping: Patterns of alternating magnetic polarity in the rock of the ocean floor provide evidence of the seafloor moving away from mid-ocean ridges. Age of the oceanic crust: Younger rocks are found nearer to mid-ocean ridges, supporting the idea of continuous seafloor creation. Ocean drilling samples: Rock samples from the ocean floor show consistent patterns of increasing age with distance from mid-ocean ridges, supporting the theory of seafloor spreading.

Or they get subducted and re-enter the mantle or they get obducted onto continent (the latter being called an ophiolite).

How is new rock added to the ocean floor?

New rock is added to the ocean floor through a process called seafloor spreading, where magma rises from the Earth's mantle at mid-ocean ridges, cools and solidifies to form new oceanic crust. This process helps expand the ocean floor and contributes to the movement of tectonic plates.


Is the underlying rock beneath the ocean floor silica?

The underlying rock beneath the ocean floor is primarily basalt, which is a mafic rock rich in iron and magnesium. Silica-rich rocks like granite are typically found in continental crust, not beneath the ocean floor.
