What it does
Join solid shapes together: ground remains wherever any input is positive. Maximum keeps the highest density at each position, so you can add a separate shape without adding all its values to the terrain.
Connect your terrain and another shape to Inputs. Inspect where they meet; if the seam looks too sharp, try Smooth Maximum to round it.
On noise
The same noise before and after this node, seen from above.
In 3D
The same output in relief: each value becomes a height, coloured like the map above. Drag to look around.
