Mechanizmy of wegetacja- Climate Interaction
Wegetation influences local weatherg three e primary biophysical pathways: evapotranspiration, albedo modification, and surface routins.

These complex interactions highlight vestication 's pivotal role in shaping miclimates and widewewewewear regional climates.

Evapotranspiration is a combinad process of evaration from soil and plant surfaces, alongside transspiration - the release of water water water frem leaf stomata.
