Germany has many different regions and shares borders with nine European countries. The northern third of the country lies in the North European Plain, with flat terrain crossed by northward-flowing watercourses and marsh conditions are found close to the Dutch border and along the Frisian Coast. Sandy Mecklenburg in the northeast has many glacier-formed lakes. Moving south, central Germany features rough and somewhat patternless hilly and mountainous countryside. Southern Germany’s landforms are defined of the Swabian and Franconian Alb, Bavarian and Black Forest.
