the crust is thicker on land so mountains
In a scene with mountains near the ocean, the Earth's crust is thickest beneath the mountains due to the presence of continental crust, which is significantly thicker than oceanic crust. Geological processes, such as tectonic activity, contribute to this thickness as mountains form and elevate the crust. Continental crust is generally around 30 to 70 kilometers thick compared to the 5 to 10 kilometers of oceanic crust beneath the ocean.
