The Kingdom of Saudi Arabia is the largest country in the Arabian Peninsula. It occupies an area about the size of the United States east of the Mississippi River. Saudi Arabia’s population is 27 million, including 8.4 million foreign residents (2010 census),  and its capital city is Riyadh.

Saudi Arabia’s geography is diverse, with forests, grasslands, mountain ranges and deserts. The climate varies from region to region. Temperatures can reach over 110 degrees Fahrenheit in the desert in the summer, while in the winter temperatures in the north and central parts of the country can drop below freezing. Saudi Arabia gets very little rain, only about four inches a year on average.
