Document Summary
Wetlands can be found in all regions of the world. Many factors affect the availability of water for wetland formation including climate, local weather, topography, surficial geology, soils, vegetation, and human activities. Climate determines the availability of water and influences soil development, which, in combination play a major role in wetland formation. Wetter climates should produce plenty of excess water for wetlands at least seasonally. For example, peatlands are extensive in western ireland, northern scotland, and wales where the surrounding waters produce high humidity with extensive cloud cover and precipitation, which when combined with the cool temperate climate promotes wetland development. A major factor in the lands ability to capture and retain water and one often related to surficial geology is topography the shape of the land surface, as reflected by. They later drained and became smaller lakes and glaciolacustrine plains. The former are depressional features that support wetlands in their shallow water zone and along their shores.
