This isolation also reflects in the fauna species and in the water salinity, which is lower than in the ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%., Mongolia (Mongolian: ["Monggol Ulus"] in Mongolian script; ["Mongol Uls"] in Mongolian Cyrillic) is a landlocked unitary sovereign state in East Asia.

Later Ilkhanate rulers, beginning with Ghazan in 1295, would convert to Islam., In physical geography, a steppe (Old Russian: "" [step'], grassland) is an ecoregion, in the montane grasslands and shrublands and temperate grasslands, savannas, and shrublands biomes, characterized by grassland plains without trees apart from those near rivers and lakes.
