North American Continent

North America is a third largest continent of the our planet. And also it can say world more powerful continent of the world.It includes 23 countries and dozens of possessions and territories. It contains all Caribbean and Central America countries, Canada, Mexico, the United States of America, as well as Greenland - the world’s largest island.Positioned in the planet's northern and western hemispheres, it's bordered in the north by the Arctic Ocean, in the east by the Atlantic Ocean, in the southeast by the Caribbean Sea and Gulf of Mexico, and in the west by the Pacific Ocean.Notice on this map that the island of Greenland, considered part of North America, is almost entirely covered by glacial ice.  In addition, much of the Arctic Ocean is ice-covered year-round, while the waters adjoining northern Canada and Alaska are often free of ice during the late summer months.  This phenomena has become more frequent and widespread in recent years, which some scientists have attributed to a global warming climate trend.  

Indeed, if this trend continues, it could open a long-sought "Northwest Passage"for shipping during several months of the year.The terrain of North America features a notable spine of mountain ranges extending from Alaska, down through western Canada and United States, reaching into Mexico and even Central America.  The ridge line of this topographical feature is known as the Continental Divide.  East of this Divide, waters flow into Hudson Bay, the Atlantic Ocean, and the Gulf of Mexico.  West of this Divide, waters flow into the Pacific Ocean.
