Geography of North America

Geography of North America

Lesson Objective

  • Describe the main geographical features of the North American continent, including its mountains, rivers, and natural resources.

Geography of North America

  • There are ten countries on the continent of North America and about 13 different nations and territorial islands in the Caribbean Sea.

  • Countries south of Mexico (Belize, Honduras, Guatemala, El Salvador, Nicaragua, Costa Rica, and Panama) are often referred to as Central America.

  • Panama marks the end point of North America and the beginning of South America.

  • Larger island countries in the Caribbean Sea include Cuba, Haiti, the Dominican Republic, and Jamaica.

  • Puerto Rico and the U.S. Virgin Islands are part of the United States, while the British Virgin Islands are part of the United Kingdom.

The Arctic North

  • North America has a large land mass that spans across the Arctic regions.

  • Some of northern Canada lies within the Arctic Circle at 663466^{\circ}34' North latitude.

  • Polar darkness occurs during the winter months, peaking on December 22nd.

  • Polar sunlight occurs during the summer months, peaking on June 21st.

  • This is due to the tilt of the Earth’s axis toward and away from the sun.

  • To the north of Canada lies the frozen Arctic Ocean and the North Pole at 9090^{\circ} North.

  • The Canadian Shield is a large sheet of rock stretching from the St. Lawrence River in Eastern Canada to the Great Lakes in Southern Canada and the northern United States. There is only a thin layer of soil, limiting farming.

  • Most of the population of Eastern Canada lives in the lower regions.

  • Western Canada and the US State of Alaska have long, high mountain ranges, coastal forests, and rivers rich with fisheries.

  • The Canadian Rockies and the Denali Range in Alaska have the highest mountain peaks in North America.

Appalachian Mountain and Great Plains

  • The Appalachian mountain range stretches from the Northeast to the South, where it gives way to a large coastal plain that spans from the Atlantic Ocean across the northern areas of the Gulf of Mexico into the Great Plains.

  • The Great Plains are a rich agricultural area with topsoil that extends from southern Canada down through the middle of the United States.

  • The Western United States is divided from the Great Plains by the Rocky Mountains.

  • Northern California has long agricultural valleys and forests that stretch up the northwest coastal mountain ranges, with the Cascade Mountain Range extending toward British Columbia in Canada.

  • The upper areas of the Northwest are quite wet with rain forests and a large amount of precipitation from rain.

  • The rest of the Far West has a dry climate with extreme cold winters in the northern areas near the Rocky Mountains, but hot dry summers.

  • The southwestern United States remains hot and dry through most of the year.

Plateaus

  • The Central Mexican Plateau is in the southern half of North America.

  • It has rich valleys set between the long Sierra Madre Occidental mountain range and volcanic mountains that surround the great plain of Mexico City.

  • Mexico’s eastern coastline borders the Gulf of Mexico.

  • The Yucatan Peninsula in Mexico’s southeast was the location of many of Mexico’s earliest sites of civilization, belonging to the Olmec and Mayan civilizations.

  • Mexico’s western coast borders the Pacific Ocean, where the climate is drier, and the area is sheltered from most tropical storms that seasonally arise in the Gulf of Mexico.

  • The Central American countries of Belize, Guatemala, El Salvador, Honduras, Costa Rica, and Panama are smaller in size and have a tropical climate.
