Mexico, known as United Mexican States (Estados Unidos Mexicanos
in Spanish). The nation's capital, Mexico City, is one of the largest
cities in the world.
Mexico is bordered by the United States on the north, the Pacific
Ocean on the west, the Gulf of Mexico and the Caribbean Sea on the
east, and Guatemala and Belize on the south.
It is characterized by an extraordinary diversity in topography
and climate and is crossed by two major mountain chains, the Sierra
Madre Occidental and the Sierra Madre Oriental.
The climate throughout Mexico is characterized by high temperatures
and moderate to low rainfall. The highland climates vary considerably
with elevation, but the central plateau generally has a moderate
climate with few extremes of hot or cold.
Mexico City, for example, has an average July temperature of 17°
C (63° F) and an average January temperature of 12° C (54° F). Cities
at lower elevations on the plateau have somewhat warmer climates.
