Which wetland has no trees and is always wet because of frequent floods and poor drainage?

• A. Marshes
• B. Swamps
• C. Bogs
• D. Fens

Answer: (A)

Wetlands differ by the plants that grow there and how water moves through them. Marshes are wetlands dominated by grasses and other herbaceous plants, with no trees. The water is in the soil for long periods because drainage is poor and floods are common, so the area stays consistently wet. That combination—no trees and constant wetness from floods and poor drainage—fits the description exactly. Swamps are characterized by trees, so they don’t match. Bogs are peat-rich and usually acidic, fed by rain rather than floods, so they aren’t defined by frequent flooding. Fens are also peatlands but are fed by groundwater and generally have different plant communities. So the best fit is marshes.
