Explanation:

Wetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season. Water saturation (hydrology) largely determines how the soil develops and the types of plant and animal communities living in and on the soil. Wetlands may support both aquatic and terrestrial species. The prolonged presence of water creates conditions that favor the growth of specially adapted plants (hydrophytes) and promote the development of characteristic wetland (hydric) soils.
Wetlands vary widely because of regional and local differences in soils, topography, climate, hydrology, water chemistry, vegetation and other factors, including human disturbance. Indeed, wetlands are found from the tundra to the tropics and on every continent except Antarctica.
Why wetlands are not found in Antarctica?
Only 0.4% of Antarctica is ice-free. Some of that has soil of a sort, but it’s usually either dry or frozen. In some locations, however, there are very short-lived patches of wet soil, for example Schirmacher Oasis and Larsemann Hills.
However, these areas don’t technically fit the definition of wetland because they lack the signature soils and vegetation of wetlands. The soil is too cold to develop hydric characteristics and the only vegetation is mosses, accompanied in photosynthesis by algae and cyanobacteria.
