What will the earth look like if surface water is ignored?

The surface water of the earth is basically the ocean, which is the most unknown world on the earth, and there are many dangerous bottomless caves on the seabed. Therefore, if we completely ignore the water on the surface of the earth, the earth may become riddled with holes, and at the same time, a large number of underwater treasures will appear, and the cracks on the surface of the earth may be completely exposed, some of which are bottomless abyss and some of which are radiant underwater treasures!
