ELI5: Difference between swamp, marsh, bog, pond, fen and other wetland terms.
gpt
It's based on plant life, water source, flow, and level, and soil composition mainly.

For an ELI5

Swamp has trees. It's basically a really wet forest with water on the ground.

Marsh has less trees more grasses

A bog has typically has peat and the ground is a mire (water/soil mixture) but it's raised up above the other terrain, fed by rain.

A fen is like a bog but it's on sloped or flatland and usually fed by underground water.
