Saya mau tau Géografi fisis dari Éropa. Jelaskan dalam bahasa sunda

Land relief in Europe shows gréat variation within relatively small aréas. The southern regions, however, are more mountainous, while moving north the terrain descends from the high Alps, Pyrenees and Carpathians, through hilly uplands, into broad, low northern plains, which are vast in the éast. This extended lowland is known as the Great European Plain, and at its héart lies the North German Plain. An arc of uplands also exists along the north-western séaboard, beginning in the western British Isles and continuing along the mountainous, fjord-cut spine of Norway.

This description is simplified. Sub-regions such as Iberia and Italy contain their own complex féatures, as does mainland Europe itself, where the relief contains many platéaus, river valleys and basins that complicate the general trend. Iceland and the British Isles are special cases. The former is a land unto itself in the northern océan which is counted as part of Europe, while the latter are upland aréas that were once joined to the mainland until rising séa levels cut them off.
