There are three processes that add material to the ocean floor:
Sedimentation, and Vulcanism.
Sedimentation is usually caused by skeletons of sea animals falling to the ocean floor. It can be argued that this is not new material but only recycled materials. But some of the remains are calcium or other deposits that are added from land based run off. Silt deposits also run into the ocean floor from the land,
Vulcanism results from shifts in the ocean mantle with new material coming from deeper in the earth and spouting through volcanoes or emerging as new ocean floor at the rising edges of the tectonic plates.
A new ocean floor is constantly being produced through the process known as seafloor spreading. An underwater mountain chain formed where new crust is created by seafloor spreading is called a mid-ocean ridge.
- The oceanic crust is thin and hot at the mid-ocean ridges where plates are pulling apart from each other. The bouyancy of magma causes it to rise and fill in the gap being created from the separating plates. The basaltic rock being created from the cooling of the magma becomes part of the crust/ocean floor. The rate of spreading is slow in human terms--about the rate of fingernail growth, but in geologic time, its How_does_sea_floor_spreading_create_a_new_ocean_floorenough to move plates all over the planet in relation to each other. Oh, and at the opposite end, oceanic crust is being swallowed up by the mantle, all part of one big conveyor belt.
- OR, in simple terms:
Seafloor spreading occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away. Jennifer Castro
Seafloor spreading. This occurs at mid-ocean ridges where tectonic plates move apart, allowing magma to rise up and solidify, forming new oceanic crust.
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

Process in which new sea floor forms as older sea floor is pulled apart?
sea-floor spreading
What is the process new crust formation called?
sea-floor spreading
What is this is the process of creating new oceanic crust?
Sea floor spreading
What are the youngest rocks on the ocean floor?
The youngest rocks on the ocean floor are located at mid-ocean ridges, where new oceanic crust is constantly being formed through volcanic activity. These rocks are typically less than 5 million years old.
Why do lakes form on the floor of a rift valley?
Lakes form on the floor of a rift valley due to the geological process of extensional tectonics, where the Earth's crust is being pulled apart. This creates a depression that can fill with water from rainfall or rivers, forming a lake. Rift valleys are often characterized by a series of interconnected lakes due to the topography and geology of the region.
Where is the youngest ocean floor in the mid-Atlantic ridge?
Down the middle! The mid Atlantic ridge is a divergent plate margin along which new crust is constantly being produced.
Vine and Matthews determined that new ocean floor was being produced at ocean ridges by examing?
the magnetic pattern on the sea floor
Why the wheat floor is exothermic?
Exothermic is the process of heat being released. Wheat flour, in order to be produced, needs to have the reaction of heat treatment. The wheat flour is exothermic due to the treatment of heat.
Is there a formal name for the process of the sea floor being older the greater the distance from the mid-ocean ridge?
Sea floor spreading
Why are sea floor rocks so young?
Sea floor rocks are young because of the process of seafloor spreading at mid-ocean ridges. As new oceanic crust forms at the ridges, older rocks get pushed further away. This continuous process creates a relatively young age for the sea floor rocks, with the oldest rocks being around 200 million years old.
How old is the sea floor?
The age of the sea floor varies, with the youngest being less than 200,000 years old and the oldest being over 200 million years old. This variation is due to the process of seafloor spreading at mid-ocean ridges and the subduction of older seafloor at deep-sea trenches.

What produces the ocean floor?
There are many things that could produced the ocean floor. Dying organisms for example are one component in the ocean floor.
