The seafloor is continuously being created at mid-ocean ridges through seafloor spreading, where tectonic plates move apart and magma rises from the mantle to create new oceanic crust. As a result, the oldest seafloor is only about 200 million years old, much younger than continental crust which can be billions of years old.
They proved that the seafloor was spreading.
The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of seafloor spreading.

Gravity in the oceanic crust is responsible for seafloor spreading.
The process that forms new seafloor is called seafloor spreading. It occurs at mid-ocean ridges where new oceanic crust is created through volcanic activity. As magma rises and solidifies, it adds to the seafloor, pushing older crust away from the ridge and creating a continuous process of crust formation.

Seafloor Spreading
The age of seafloor bedrock increases with distance from a mid-ocean ridge. At the ridge, the bedrock is young, as it is continuously being formed by volcanic activity. As it moves away from the ridge through the process of seafloor spreading, it cools and ages over time.

The youngest seafloor rocks are typically found along mid-ocean ridges, where tectonic plates are moving apart and new crust is continually forming. This process, known as seafloor spreading, leads to the creation of young rocks that are progressively older as you move away from the ridge axis on either side.

The ocean seafloor is a home to many descriptive sea creatures.
Seafloor spreading is triggered by a rift in a continental land mass.
