it becomes part of the oceanic crust
because the molten rock cools in the water and forms a oceanic crust
Oceanic crust is denser than continental crust because it is formed from basaltic magma at mid-ocean ridges, which cools quickly and is more compact. This denser oceanic crust tends to sink lower into the mantle compared to the less dense continental crust, which is primarily composed of less dense granite rocks.
As the lithosphere cools, asthenosphere's hot rocks freeze onto their undersides. So lithosphere becomes thicker. As time goes on or within the time period of 10 million years, it even becomes thicker than asthenosphere.
No. New oceanic crust is formed at a divergent boundary. A convergent boundary neither creates nor destroys crust.
Ocean crust is formed through a process called seafloor spreading, where magma rises up at mid-ocean ridges, cools, and solidifies to create new crust. This process is part of plate tectonics, where oceanic plates move away from each other, allowing new crust to form at the ridges.
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.

Actually nothing significant happens after that, the cycle just continues. Are you sure you wanted to know what happens when a new oceanic crust forms or how is a new oceanic crust formed? If you meant how a new oceanic crust is formed then here is the answer>>>> New oceanic crust forms when the divergent plate margins move away from each other leaving a gap, then magma rises to fill that gap, then it cools and turns solid and forms new land. :) I hope this was helpful!
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
New oceanic crust and lithosphere are formed at mid-ocean ridges through the process of seafloor spreading. As tectonic plates diverge, magma from the mantle rises to fill the gap, cools, and solidifies, creating new basaltic crust. This newly formed crust is part of the lithosphere, which includes the rigid outer layer of the Earth. Over time, the new crust moves away from the ridge, contributing to the dynamic nature of plate tectonics.
Oceanic crust is created at mid-ocean ridges and (through the creation of new oceanic crust) is pushed toward a convergent plate boundary where it is subducted. So the oldest oceanic crust would be located at a convergent plate boundary where the oceanic crust is being subducted under continental crust.
The force driving the process of pulling dense pieces of oceanic crust downward towards the mantle is gravity. As oceanic crust cools and becomes denser, it sinks into the mantle due to gravitational forces. This process is known as subduction.
