Three common types of wetlands?

• A. Marshes, swamps, and wetlands
• B. Marshes, wetlands, and rivers
• C. Ponds, lakes, and wetlands
• D. Rivers, marshes, and swamps

Answer: (A)

Wetlands are water-saturated environments that include distinct forms with characteristic plants and soils. The three common types you’ll encounter are marshes, swamps, and bogs (peat-forming wetlands, sometimes including fens). Marshes are dominated by grasses, reeds, and other herbaceous plants and often have open water or shallow areas. Swamps feature woody plants—trees and shrubs—growing in flooded soils. Bogs and similar peatlands are acidic, waterlogged places where peat builds up from partially decomposed plant material, supporting specialized vegetation.

This set fits the topic better than options that list general bodies of water like rivers or lakes, which are not wetlands themselves. The term wetlands describes the ecosystem category, while marshes, swamps, and peat-forming wetlands like bogs or fens are the classic types within that category.
