Answer 1

this is the default texture for a terrain.

click on the terrain and a menu should open up at the inspector, where you have a few options.

in the Project window, go to the assets folder and right click + pick create a new terrain layer.

than, you can drag this layer to the terrain and have a texture on it.

you can even drag more than one layers to have multiple textures on it.

on the height problem: try installing the unity terrain tools package or checking if the terrain is read only.
