What lanforms can isolate people?

Landforms that can isolate people include mountains, which create natural barriers that make travel difficult; deserts, which can be inhospitable and limit access to resources; and large bodies of water, such as oceans and lakes, that separate communities and restrict movement. Additionally, dense forests and swamps can hinder transportation and communication, further isolating populations. These geographic features can lead to cultural and social separation, as well as challenges in trade and interaction.
