What it does
Start a flat world at the height you choose. The surface sits at Height, but the positive side faces upwards: used directly as terrain, it fills the sky.
Connect Output to Negate to put solid ground underneath the surface. You can then add scaled noise with Sum to raise hills and lower valleys.
In 3D
The noise shaping real terrain: added to a slope from solid ground to open sky, it carves overhangs, caves and floating pieces.

Good to know
Build the flat ground first
Check the ground with Negate before adding noise. It is easier to judge hill height against a surface you already recognise.
