The mid-atlantic Ridge. There, two tectonic plates are pulling apart, and magma from the mantle rises to the space between these two plates. This magma is cooled instantly, becoming a new ocean floor.
What else can I help you with?
Why is the seafloor young?
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.
Which type of boundaries is seafloor created by?
Seafloor is created at divergent plate boundaries called the mid-ocean ridges.
Process that forms new seafloor?
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.
What feature on the ocean floor would you most likely find the oldest seafloor?
in a subduction trench, because of Harry Hess' theory of sea floor spreading. Meaning that the rock is formed new at the mid-ocean ridge, and moved out towards the coasts into a subduction zone years and years later.
What is the name of places where new seafloor is created?
New oceanic crust is created at spreading centres. These may also be termed divergent or constructive plate boundaries or Mid-Ocean-Ridges.
What seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
Seafloor Spreading
Places where new seafloor is being created?
New seafloor is created at mid-ocean ridges, where tectonic plates are moving apart. As the plates separate, magma from the mantle rises to the surface, solidifies, and forms new crust. This process is known as seafloor spreading.

Does seafloor spreading cause the earth's crust to expand?
Yes, seafloor spreading is a process where new oceanic crust is formed at mid-ocean ridges, causing the Earth's crust to expand. This occurs as magma rises to the surface, solidifies, and pushes older crust away from the ridge, creating new seafloor.
If new seafloor is being created how does the earth stay the same size?
Because it only gets larger in one direction by getting smaller in another. In the case of ocean ridges, the 'other place' is wherever the crust has subducted into the natle at a plate boundary.
What is the place that new seafloor is created?
in mid ocean ridges
Which type of boundaries is seafloor created by?
Seafloor is created at divergent plate boundaries called the mid-ocean ridges.

What boundary seafloor destroyed?
Subduction zones are boundaries where the seafloor is destroyed. This happens when one tectonic plate moves beneath another, causing it to sink into the mantle and be reabsorbed. This process can lead to the formation of deep ocean trenches and volcanic arcs on the Earth's surface.
What is the name of places where new seafloor is created?
New oceanic crust is created at spreading centres. These may also be termed divergent or constructive plate boundaries or Mid-Ocean-Ridges.
Is the seafloor recycled?
Yes, the seafloor is recycled through the process of plate tectonics. Oceanic plates are constantly being created at mid-ocean ridges and destroyed at subduction zones, where one plate is pushed beneath another and melts into the mantle. This cycle of creation and destruction helps to regulate the Earth's surface and contributes to geological processes such as earthquakes and volcanic activity. Thus, the seafloor is continuously renewed over geological time scales.
