Denmark is located on the peninsula and islands that separate the North Sea from the Baltic Sea. Unlike the soil of other Nordic countries, the Danish soil consists mainly of sand and clay that have accumulated in the region after the last Ice Age.

Denmark contains only a few lakes and small rivers. It also consists mostly of lowland areas. The highest point of Denmark is located only 172 meters above sea level. 

Denmark's flat geography and temperate climate make it suitable for large-scale agriculture.

Many Danish islands have been connected with each other by building bridges. The Øresund Bridge is one of the longest bridges. It connects the Danish metropolitan area of Copenhagen with the Swedish city of Malmö, and is almost 8 kilometers long.
