Gullies are formed by running water. The water washes down to low point, and the flow slowly erodes the dirt into a gully.

Divides are the boundaries that separate streams in adjacent drainage basin.

I believe Badgers do.
Unlike gullies, streams rarely dry up.
Streams are different from gullies because it doesn't dry up.

Ephemeral streams are streams that only have running surface water after a rain storm. During most of the year they are dry gullies or arroyos.
Precipitation -- rain and snow cause flowing water in nature.
Rills are small channels formed by flowing water on a slope, gullies are larger and deeper channels typically caused by erosion, and streams are larger bodies of moving water that can support aquatic life and flow towards a larger body of water like a river or ocean.
Runoff causes erosion which makes ripples in the ground and the some ripples turn into gullies (small rivers or streams) that may end up like the Grand Canyon..

Nothing Natural features would include changing elevations (gullies right up to mountains), volcanos, rivers/streams/creeks, and vegetation.
