Mexico is crossed by two major mountain ranges: the Sierra Madre Occidental and Sierra Madre Oriental. The Sierra Madre Occidental to the west is the continuation of the Sierra Nevada of California and the Sierra Madre Oriental in the east is the continuation of the Rocky Mountains of New Mexico and Texas. Between the two main mountain ranges lies the Mexican plateau. Cordillera neovolcanic marks the southern boundary of the Sierra Madre Occidental and Oriental. Mexico has also other mountain ranges less important as the assembly line in California, the Sierra Madre del Sur, Sierra Madre de Oaxaca, Sierra Madre de Chiapas, and the Meseta Central de Chiapas.
Mexico has about 150 rivers. 2 / 3 of them drain into the Pacific Ocean and 1 / 3 in the Gulf of Mexico or the Caribbean Sea. Despite the apparent abundance of water, the volumes of water are distributed in very unequal across the country. Indeed, five rivers (the Usumacinta, the Grijalva, the Papaloapan the Coatzacoalcos and Pánuco) totaled 52% of the average annual volume of water. These five rivers (currently very polluted) draining into the Gulf of Mexico. Only the Rio Panuco is not in the Mexican southeast. The northern and central Mexico, covering 47% of the territory and Nearly 60% of the population have less than 10% of the water resources of the country
