Final Answer:
The country separated from Sweden by the Kattegat, linking the North and Baltic Seas, is Denmark.
Step-by-step explanation:
The Kattegat is a sea area situated between Sweden and Denmark, connecting the North Sea to the Baltic Sea. It serves as a vital maritime passage for ships traveling between these two significant bodies of water. Denmark, located to the southwest of Sweden, is the country separated by the Kattegat. This waterway has historical and strategic importance, influencing trade routes, naval activities, and the cultural and economic ties between Denmark and Sweden.
Geographically, the Kattegat plays a crucial role in shaping the Scandinavian Peninsula. The waters of the Kattegat flow into the Skagerrak to the west and the Øresund to the south, further connecting to the Baltic Sea. Denmark, being positioned on both sides of the Kattegat, has a substantial maritime presence and plays a key role in the interactions and relationships among the Nordic countries. The shared history, cultural exchanges, and economic partnerships facilitated by the Kattegat underscore the interconnectedness of the region and the significance of this sea area in shaping the geopolitical dynamics of Northern Europe.
