land bridge

A land bridge is a strip of land that connects two larger landmasses, allowing plants, animals, and humans to travel between them when sea levels are lower or conditions change. These natural formations have historically enabled migration and exchange of species across regions. For example, the Bering Land Bridge once connected Asia and North America during the Ice Age, facilitating the movement of early humans and animals. Land bridges typically form due to shifts in sea levels or geological processes, and over time, they may be submerged as conditions change.
