On geologic time scales, new oceanic crust is constantly being formed ad mid-ocean ridges while older crust is destroyed at subduction zones. The crust forms at the ridge and is carried away by the movement of the plate as new crust forms to take its place. The oceanic crust is youngest new a mid ocean ridge and oldest far away from it.

The oldest rock in oceanic crust is that which is found the greatest distance from a mid-ocean-ridge.
Evidence supporting seafloor spreading includes the symmetrical patterns of magnetic stripes on either side of mid-ocean ridges, which show reversals in Earth's magnetic field over time. Additionally, the age of oceanic crust increases with distance from the ridge, indicating that new crust is formed at the ridge and gradually moves outward. The presence of deep-sea sediments also supports this theory, as they are thinner and younger near the ridges and become thicker and older further away. Finally, the distribution of earthquakes and volcanic activity along mid-ocean ridges aligns with the movement of tectonic plates.
The movement of ocean floor on either side of a mid-ocean ridge is known as seafloor spreading. As new oceanic crust is formed at the ridge, it pushes the existing crust away from the ridge in opposite directions, creating a continuous process of plate tectonics.

The mid-ocean ridge is where new oceanic crust is formed as tectonic plates pull apart. This process, known as seafloor spreading, allows magma to rise from the mantle, solidify, and create new oceanic crust. As the crust forms at the mid-ocean ridge, it pushes older crust away, driving the movement of lithospheric plates.
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
On geologic time scales, new oceanic crust is constantly being formed ad mid-ocean ridges while older crust is destroyed at subduction zones. The crust forms at the ridge and is carried away by the movement of the plate as new crust forms to take its place. The oceanic crust is youngest new a mid ocean ridge and oldest far away from it.
Oceanic crust that was farther away from a mid-ocean ridge was older that crust closer to the ridge

Mid-Ocean ridge
Core samples would reveal that the further from the mid-ocean ridge you go, the greater the overlying sediment on top of the basaltic crust. This would indicate that the crust closer to the ridge was younger and more recently formed. The creation of new crust at mic-ocean ridges is the crucial evidence for the movement of tectonic plates.
The Oceanic Crust close to the Mid Ocean Ridge is thinner than that Oceanic Crust far away from the ridge. This is due to tensional forces, as a result of crustal expansion and rock fracturing during the formation of the ridge.the oceanic crust is thinner
