This mountain chain is crossed by many faults. They start from the ocean and over land. Cordillera was the result of a convergence of two lithospheric plates. But, according to scientists, seismologists, the process of mountain building is still not completed. This is also evidenced by the presence of several active volcanoes, are still more of them “sleep”. Frequent in this zone, and earthquakes. If we talk about the height of these mountains, with them, perhaps rivaled only by the Himalayas. The highest point in North America, mount McKinley, is also in the Cordillera. Its height is 6193 meters. What else remarkable to say about Cordillera? They lie in all geographic zones, except the Arctic.

And the Appalachian

The Appalachian mountains – mountains in North America, they are divided into two parts: North and South. Of course, the boundaries of these conditional. Northern Appalachia is much older than the main part of the mountain range. Currently, they represent a plateau height of 400-600 meters. Rise above it places certain ranges and arrays. The most famous of them – the Adirondacks, the White mountains, Green mountains. The peaks are smoothed. Slopes are mostly gentle, but sometimes there are areas dissected punishments. Mountain ranges divide the tectonic valley. They are converted to camping village Il poggetto. Northern Appalachian mountains, the local people have another name – ‘mountains of New England”. They are composed of metamorphic and crystalline rocks. This site is pereplanirovana mountains, in which there are feeble traces of later uplift. But clearly the impact of glaciation.

Southern Appalachians

In the East – the Piedmont plateau the Piedmont. It is flat, weakly dissected valleys. Its height is 40–80 meters. In the Western part is more hilly. Here, the height reaches 400 meters. But more interestingly, in this region rise abruptly massive peaks. This Is The Blue Ridge Mountains. Its slopes are steep. Tops often dome-shaped or comb-shaped. The highest point – mount Mitchell. The height of 2037 meters. It is composed of sedimentary-volcanic rocks belonging to the lower and middle Paleozoic. The Western slope of the Blue Ridge mountains drops steeply to a decrease – a Large Valley. There is Appalachins plateau. Mountains separated by valleys, descending to 1500 meters.

Sierra Nevada

In the East of the Sierra Nevada is bordered by the Large swimming Pool. Of course, the highest mountain in North America is not located in the area, but those that exalted here can rightly be called the most picturesque. The crest of the ridge runs along the slope on the West side. All the rivers, the origins ofwhich are on the peaks, drains into the Pacific ocean. From North to South is gradually increasing the height of the mountains. Between lake Tahoe and pass Fredonyer peaks reach 2400 meters. The highest point on this segment of the ridge is mount rose. Its height is 2700 meters. On the territory of Yosemite national Park is Olancha peak (3695 m) and Florence (3781 m). Further, the height of the ridge is on the decline.

In the North there are several mountain tops at an altitude from 1000 to 3000 m In the South mountain ranges are isolated from each other. There is separate peaks rising to 4,000 m In the Western part of the plateau in several places depart spurs. The East ridge ends on the coastal plain of the Gulf of Mexico. The greater part of the Eastern Sierra–Madre is formed by sedimentary rocks belonging to the upper Mesozoic period. The highest point of the ridge – peña Nevada (4054 m). But this is not the only peak worth mentioning. No less famous mountains of El Coahuilan and Cerro Potosi.

Western Sierra Madre

These mountains in America considered to be a continuation of the Cordillera. They are located on the territory of modern Mexico. The length of the Western Sierra Madre – 1300 km and Width of this mountain range, from 80 to 200 km. It is located on the Western part of the Mexican plateau.

Then he goes towards the isthmus of Tehuantepec. He crosses the Mexican States such as Guerrero and Oaxaca, where it merges with Transmexican volcanic belt. The width of the southern Sierra Madre of 300 km, These mountains are low, only a few peaks reach above 3,000 m. But despite this, the region is a serious obstacle to the transport of messages between the internal parts of Mexico and Pacific coasts. The highest point in the southern Sierra Madre mountain Teotepec (3703 m).

Coast mountains
