Temperature of the oceanic crust
As the oceanic crust descends beneath the continental crust, the mantle rock is subjected to high pressure and temperature. This causes the mantle rock to partially melt, producing magma that can rise to the surface and form volcanoes. The interaction of the descending oceanic crust with the continental crust can also lead to earthquake activity.
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.

The geothermal gradient in the Earth's oceanic crust is around 25-30°C per kilometer depth. This means that the temperature increases by about 25-30 degrees Celsius for every kilometer of depth below the seafloor in oceanic crust.
Oceanic crust is significantly denser.
The youngest parts of the Earth's crust are found in the oceanic crust. This crust is continuously being created at the mid-oceanic ridges.
The lithosphere is generally thinner under oceanic crust compared to continental crust. Oceanic lithosphere is typically around 5-10 kilometers thick, while continental lithosphere can be up to 200 kilometers thick. This difference is due to variations in temperature and composition between the two types of crust.

Continental crust is far older than oceanic crust.
