The Finnish bedrock belongs to the old Fennoscandian plate, where only small parts are younger than 1 800 million years. The basement is visible in many places. The oldest part of the bedrock is the archeological bedrock of 2,800-2,700 million years old in eastern and northern Finland. The majority of Finland’s bedrock accounts for 1,930-1,800 million years ago of the svekofennic bedrock born in the early stratospheric period. In northern Lapland there is a significant granulitis body. The most significant of the younger bedrocks are rapakivigranites born in Southern Finland between 1 650 and 1 540 million years ago in the middle martial art. 
Finland’s area is 338,449 km² (2017). Includes land and inland waters. Furthermore, sea areas are 52 471 km².  Due to landslide, the land area grows every year about 7 km². 4% of agricultural land, agricultural land 9%, forestry 77% and other land 10%.  The southern part of the country and the coast of Ostrobothnia are flat, but in Central Finland the terrain becomes cloudy. The dangers of Eastern Finland and the Lapland Mountains are the remains of the Karelid Mountains stretching from Eastern Karelia to Lapland. The highest fells in Lapland Lapland are in Skandia, with bedrocks of between 400 and 450 million years. The highest point in Finland is the Haltitunturi, part of the Skande, whose slope rises on the Finnish side to 1 324 meters above sea level. 
The most common mineral species is a sea urchin, on which some clay is sometimes colonized. Peat from the organic peatland has formed peat and the cloth fabric in the fabric. At the end of the last Ice Age, the edges of the glaciers along the edges of the glacier and the rungs in the direction of the movement are Finland’s characteristic terrain patterns. The most significant are the Salpausselät, which cross the southern part of Finland from south-west to northeast. The most famous of the longitudinal troughs are Pyynikinharju Pirkanmaa, which is the highest in the world, the source? and Punuharju Saimaa in Puruvesi.
There are exceptionally many lakes in Finland. In total, a total of 187,888 lakes of more than 500 square meters are counted in the country. The largest lake is Saimaa and the deepest Päijänne. Lake Järvi Finland is the largest lake in Finland. The lakes are broken, rich and mostly shallow, with a mean depth of seven meters. Lakes form rivers through lake routes and these waters. The largest waters are the waters of Vuoksi, Kymijoki, Kokemäenjoki, Oulujoki and Kemijoki. Like lakes, the coasts are broken and rich. The Turku Archipelago and the Åland Archipelago form the second most archipelago of Europe. The largest island is the Sääminginsalo (1,069 km²) on Saimaa and the second largest Åland main island (685 km²). There are 179 584 islands in Finnish sea areas and inland waters.
