how can i make the volumetric clouds bend accordingly to the world curvature?
and how can i make that the volumetric cloud material fades when colliding with something?

In the material editor you can add a node called Cloud Sample Attributes node. That has multiple useful outputs. You probably want the NormAltitude, that returns a 0 at the bottom edge of the cloud layer and 1 at the top. This works globally.

So you can use the NormAltitude as an input for your heightmask and then apply it to your clouds. I would also simply use 3D noise as a base shape for the clouds, so after applying the heightmask you get nice glouds globally.

That should get you started.
