Study Notes
Formation of Continents
- Continents were once a single supercontinent named Pangaea, surrounded by the ocean Panthalassa.
- Alfred Wegener proposed the Continental Drift Theory in 1912, explaining the movement of continents.
- Pangaea split into two major blocks: Laurasia (North America, Europe, Asia) and Gondwana (South America, Africa, Australia, Antarctica, India).
- The Tethys Sea formed between Laurasia and Gondwana as they drifted apart.
- About 65 million years ago, North America separated from Laurasia; South America, Africa, India, Madagascar, Australia, and Antarctica separated from Gondwana.
- The Atlantic Ocean formed from the westward drift of North and South America; the Indian Ocean formed from India's northward drift.
- The Plate Tectonics Theory advanced the understanding of continental movement based on shifts in tectonic plates, moving slowly on the Earth's molten mantle.
History of North America
- Christopher Columbus is credited with discovering North America, but Vikings likely arrived first.
- Native American tribes and the Aztec civilization inhabited North America before European colonization.
- The United States, the most populous country in North America, emerged in the late 1700s and is considered a "melting pot" of cultures.
- Paleo-Indians are believed to be among the first inhabitants, migrating from Asia.
Location and Boundaries
- North America is situated in the Northern and Western Hemispheres, bordered by the Pacific, Atlantic, and Arctic Oceans.
- Major features include the Arctic Ocean to the north, the North Atlantic Ocean to the east, and the Caribbean Sea to the southeast.
- It connects to South America via the Isthmus of Panama, where the Panama Canal was constructed.
Countries and Capitals
- Major countries: Canada, USA, Mexico; smaller countries cluster in the central region.
- Greenland is an autonomous territory of Denmark, with Nuuk as its capital.
- English, Spanish, and French are the primary languages due to historical colonization.
Major Physical Features
- Four main physical divisions: Western Cordilleras, Great Plains, Eastern Plateaus, Central Lowlands.
- Western Cordilleras: Features young fold mountains like the Rocky Mountains; important plateaus include the Columbia and Colorado Plateaus; includes the Grand Canyon.
- Great Plains: Vast semi-arid grasslands drained by major rivers.
- Eastern Plateaus: Extend from Hudson Bay to the Gulf of Mexico, include the Appalachian Mountains, Piedmont Plateau, and Atlantic Coastal Plain.
- Central Lowlands: Fertile plains suitable for agriculture and livestock.
Mountain Ranges
- Rocky Mountains: Longest mountain range in North America, with peak Mt. Elbert at 4,399 meters; diverse wildlife.
- Appalachian Mountains: Oldest mountain chain, running from Newfoundland to Alabama; includes popular subranges like the Great Smoky Mountains.
- Sierra Madre: Mountain range along Mexico’s Pacific Coast, characterized by rainforests and volcanoes; highest point is Mount Whitney.
- Adirondack Mountains: Located in New York, highest point is Mount Marcy; features the largest state park in the U.S.
- Brooks Range: Extends 1,100 km across Alaska, with Mount Chamberlin being the highest at 2,749 meters.
- Cascade Range: Known for volcanoes, part of the Pacific Ring of Fire, highest point is Mount Rainier.
Water Bodies
- North America is bordered by the Pacific, Atlantic, and Arctic Oceans and contains significant seas, gulfs, and bays.
-
Major Rivers:
- Missouri River: Longest river (3,767 km), flows into the Mississippi.
- Mississippi River: Second longest (3,734 km), forms one of the largest drainage basins in the world.
- Colorado River: Notable for the Grand Canyon and significant dams; vital for water supply.
- St. Lawrence River: Major eastern Canadian waterway draining the Great Lakes.
- Hudson River: Historically significant, flows through New York.
- Mackenzie River: Longest river in Canada, flows into the Arctic Ocean.
Lakes
- Great Lakes: Comprising Lake Superior, Michigan, Huron, Erie, and Ontario; hold 21% of the world's fresh water supply, providing vital transportation routes.
Deserts
- North America features four deserts: Great Basin, Chihuahuan, Sonoran, and Mojave, primarily located in the western region.
- Great Basin Desert: Largest, cold desert mostly in Nevada.
- Chihuahuan Desert: Located along the US-Mexico border.
- Sonoran Desert: Found in California, Arizona, and Mexico, with major rivers flowing through.
- Mojave Desert: Positioned between the Great Basin and Sonoran deserts, spans California, Nevada, and Arizona.
