Question

wetlands are defined by:
○ high elevation
○ rocky terrain
○ presence of water and hydric soils
○ lack of vegetation

Explanation:

Wetlands are areas where water is present (either permanently or seasonally) and have hydric soils (soils saturated with water, leading to anaerobic conditions). High elevation, rocky terrain, and lack of vegetation are not defining features of wetlands (wetlands often have unique vegetation adapted to wet conditions). So the correct option is the one about presence of water and hydric soils.

Answer:

C. Presence of water and hydric soils (assuming the options are labeled A to D with A: High elevation, B: Rocky terrain, C: Presence of water and hydric soils, D: Lack of vegetation)
