North America

A continent of mountains, forests, plains, deserts, lakes and diverse cultures

Overview

North America is the third-largest continent by area and is located primarily in the Northern and Western Hemispheres. It extends from the Arctic Ocean in the north to the Caribbean Sea and the northern regions of South America in the south.

The continent includes Canada, the United States, Mexico, the countries of Central America and the nations of the Caribbean. Greenland, geographically part of North America, is the world's largest island.

North America contains an exceptional variety of landscapes, including Arctic tundra, boreal forests, temperate forests, prairies, deserts, tropical forests, mountains, large river systems and extensive coastlines.

Key fact: North America contains Greenland, the world's largest island, and the Great Lakes, one of the largest freshwater systems on Earth.

The Great Lakes

The Great Lakes form one of the world's largest interconnected freshwater systems. They are located along the border between Canada and the United States.

Lake Key characteristic
Lake Superior Largest of the Great Lakes by surface area.
Lake Michigan The only Great Lake located entirely within the United States.
Lake Huron One of the largest freshwater lakes by surface area.
Lake Erie The shallowest of the five Great Lakes.
Lake Ontario Easternmost Great Lake, connected to the Atlantic through the St. Lawrence River.

Deserts

The western and southwestern parts of North America contain extensive arid and semi-arid environments.

These environments contain distinctive geological formations, vegetation and wildlife adapted to low rainfall.

Climate

North America experiences an enormous range of climates because of its size, latitude, elevation and mountain systems.

Arctic climate

Northern Canada, Greenland and parts of Alaska contain Arctic environments characterised by extremely cold winters, tundra and extensive seasonal sea ice.

Temperate climate

Large parts of Canada and the United States have temperate climates with substantial seasonal variation.

Desert climate

Southwestern North America contains several major deserts and semi-arid regions.

Tropical climate

Southern Mexico, Central America and the Caribbean contain tropical environments with warm temperatures throughout much of the year.

Mediterranean climate

Parts of California have a Mediterranean climate characterised by dry summers and wetter winters.

Forests and Ecosystems

North America contains a remarkable range of ecosystems.

Wildlife

North America supports a diverse range of mammals, birds, reptiles, amphibians, fish and marine organisms.

Marine Environments

North America has extensive coastlines bordering the Arctic, Atlantic and Pacific Oceans, as well as the Caribbean Sea and Gulf of Mexico.

Important marine regions

History of North America

North America has a long and complex human history extending back thousands of years before European exploration.

Indigenous civilisations

Indigenous peoples developed diverse societies, cultures, languages, technologies and political systems throughout North America.

Mesoamerican civilisations

Mesoamerica was home to major civilisations including the Maya and Aztec. These societies made important contributions to astronomy, mathematics, agriculture, architecture and political organisation.

European exploration

European exploration of North America began during the late fifteenth century and subsequently led to extensive colonisation, migration and economic transformation.

Formation of modern states

The modern political geography of North America developed through processes including independence movements, territorial expansion, treaties, migration and the formation of national governments.

Science and Technology

North America has become a major global centre for science, engineering, medicine, computing and technological innovation.

Field Examples
Space Science Planetary exploration, astronomy, human spaceflight and satellite technology.
Computing Software engineering, artificial intelligence, semiconductors and computer science.
Aerospace Aircraft, spacecraft, propulsion, avionics and autonomous systems.
Medicine Biomedical research, pharmaceuticals, biotechnology and clinical medicine.
Engineering Civil, mechanical, electrical, chemical, automotive and aerospace engineering.

Major Cities

North America contains many major metropolitan regions that act as centres of finance, industry, education, culture and technology.

Economy

North America contains some of the world's largest and most technologically advanced economies.

Major economic sectors

The Great Plains are particularly important for grain production and livestock farming.

Energy and Natural Resources

North America has substantial natural resources, including fossil fuels, minerals, forests, freshwater and agricultural land.

Renewable Energy

North America has substantial potential for renewable energy.

The continent's large size and varied geography provide many different renewable energy resources.

Environmental Challenges

North America faces environmental challenges associated with climate change, habitat loss, pollution, resource use and biodiversity conservation.

Climate change

Climate change affects Arctic environments, forests, agriculture, water supplies, coastal areas and marine ecosystems.

Arctic change

The Arctic regions of Canada, Alaska and Greenland are particularly sensitive to changes in temperature and sea ice.

Wildfires

Large wildfires occur naturally in many North American ecosystems, but changing climate conditions can influence wildfire risk, duration and intensity.

Water resources

Water availability is a major issue in parts of western North America, particularly in arid and semi-arid regions.

Biodiversity

Conservation programmes seek to protect habitats, endangered species, forests, wetlands, grasslands and marine ecosystems.

North America and the Arctic

Northern North America extends deep into the Arctic region. Canada, Greenland and Alaska contain extensive Arctic landscapes.

The Arctic is important for climate science, wildlife, Indigenous communities, shipping, natural resources and international geopolitics.

North America and Space Exploration

North America has played a major role in the development of modern space exploration. Scientific and engineering programmes have contributed to human spaceflight, planetary exploration, astronomy, satellite communications and Earth observation.

The continent is home to major aerospace research centres, universities, observatories and space organisations.
