What is the geo model in linguistics?

The geography model, or geo model, focuses on the geographical proximity of languages and their influence on each other due to their climate and locations on Earth. Unlike the tree model, which emphasizes historical relationships, or the wave model, which highlights diffusion, the geo model examines the impact of geographic proximity on linguistic similarities, differences, and shared features among languages in a particular region. It considers the exchange of linguistic traits through contact and interaction in a specific geographical area.
