The United Kingdom is a small nation in physical size. At 244,110 sq km (94,250 sq mi), the United Kingdom is roughly the size of Oregon or Colorado, or twice the size of New York State. It is located as far north in latitude as Labrador in North America, but, like the rest of northern Europe, it is warmed by the Gulf Stream flowing out of the South Atlantic Ocean. The climate, in general, is mild, chilly, and often wet. Rain or overcast skies can be expected for up to 300 days per year. These conditions make Britain lush and green, with rolling plains in the south and east and rough hills and mountains to the west and north.
