Galicia is quite mountainous, a fact which has contributed to isolate the rural areas, hampering communications, most notably in the inland. The main mountain range is the Macizo Galaico (Serra do Eixe, Serra da Lastra, Serra do Courel), also known as Macizo Galaico-Leones, located in the eastern parts, bordering with Castile and Leon. Noteworthy mountain ranges are O Xistral (northern Lugo), the Serra dos Ancares (on the border with Leon and Asturias), O Courel (on the border with Leon), O Eixe (the border between Ourense and Zamora), Serra de Queixa (in the center of Ourense province), O Faro (the border between Lugo and Pontevedra), Cova da Serpe (border of Lugo and A Coruna), Montemaior (A Coruna), Montes do Testeiro, Serra do Suido, and Faro de Avion (between Pontevedra and Ourense); and, to the south, A Peneda, O Xures and O Larouco, all on the border of Ourense and Portugal.

What is Galicia's main mountain range?

Everything in between the far south and the far north is savannah (insignificant tree cover, with grasses and flowers located between trees). Rainfall is more limited, to between 500 and 1,500 millimetres (20 and 60 in) per year. The savannah zone's three categories are Guinean forest-savanna mosaic, Sudan savannah, and Sahel savannah. Guinean forest-savanna mosaic is plains of tall grass interrupted by trees. Sudan savannah is similar but with shorter grasses and shorter trees. Sahel savannah consists of patches of grass and sand, found in the northeast. In the Sahel region, rain is less than 500 millimetres (20 in) per year and the Sahara Desert is encroaching. In the dry north-east corner of the country lies Lake Chad, which Nigeria shares with Niger, Chad and Cameroon.

How many inches of rain does central Nigeria get each year?
Answer:
between 500 and 1,500 millimetres (20 and 60 in)
