New crust is being generated at divergent boundaries of separating plates.
At a volcanic island arc, an oceanic plate slides into the mantle and thus oceanic crust is destroyed. The volcanoes add material on to of the crust, but to not cause the crust to expand outward.
Yes, new oceanic crust is generated every day through a process known as seafloor spreading. This occurs at mid-ocean ridges where tectonic plates diverge, allowing magma from the mantle to rise and solidify as it cools. While the rate of crust formation varies, it is a continuous process that contributes to the dynamic nature of Earth's geology.
New crust is constantly being formed at mid-ocean ridges through volcanic activity. However, the Earth does not get larger because as new crust is formed, older crust is subducted back into the mantle at subduction zones, maintaining a relatively constant amount of crust on the Earth's surface.
New crust is continually being formed at mid-ocean ridges through the process of seafloor spreading. Magma rises from the mantle and solidifies at the ridges, creating new crust as tectonic plates move apart. The crust then slowly spreads outward as more magma comes up, constantly renewing the Earth's surface.
Magnesium is used to support the theory of seafloor spreading because as new oceanic crust forms at mid-ocean ridges, it contains higher levels of magnesium compared to older crust. This can be observed through magnetic anomalies in the oceanic crust, where variations in magnesium content create distinct magnetic stripes that align with the spreading centers. This provides evidence that new crust is being continuously generated at mid-ocean ridges, supporting the process of seafloor spreading.

New oceanic crust is continually being created at the Mid-Ocean ridges.

the mantle
oceanic crust is constantly being subducted and replaced with new material at places like the mid Atlantic ridge.
near ocean trenches.
Since the rock just came up and cooled, it's "new oceanic rock." Because... it's new rock. It's the youngest rock. It just came out of the ground and cooled, making it rock. Or Because new crust is being formed while the old crust is being pushed away.
