Final answer:
Wetlands are environments saturated with water and exhibit a near continuous cover of emergent vegetation. They can form near lakes or be perched at higher elevations. Examples of wetlands include marshes, swamps, bogs, mudflats, and salt marshes.
Step-by-step explanation:
Wetlands are environments in which the soil is either permanently or periodically saturated with water. They differ from lakes because wetlands are shallow bodies of water with a near continuous cover of emergent vegetation.
Wetlands can form near lakes at the same level as the water table or be perched at higher elevations where materials trap precipitation and runoff and slow infiltration. Examples of wetlands include marshes, swamps, bogs, mudflats, and salt marshes.
