What two geographic features mark the edges of the Europe continent east an west?

The eastern edge of the European continent is marked by the Ural Mountains, which separate Europe from Asia, while the western edge is defined by the Atlantic Ocean. These geographic features play a significant role in shaping the cultural and historical boundaries of Europe. The Ural Mountains extend from the Arctic Ocean to the Caspian Sea, whereas the Atlantic Ocean provides a natural boundary between Europe and North America.
