North America is the third largesr continent. Three countries - Canada, the United States, and Mexico - make up most of it. The countries of Central America are also usually considered part of North America. They occupy a narrow of strip of land that connect North America to South America. Several islands, including Greenland in the north and the West Indies in the south, are part of North America too.
Because it's so large, the continent has many different types of climate. Most of Greenland is covered with ice all the time - even in summer. But the southern islands and countries are usually hot and humid. In between there are both deserts and rainy areas, but most places have warm summers and cold winters.
North America is rich in natural resources. Forests cover a large part of the land. The fertile soils of Canada, the United States, and Mexico produce large amounts of maize, cotton, soybeans, tobacco, wheat, and other crops. The continent is also rich in minerals such as coal., iron ore, copper, natural gas, oil, and silver.
The history of the continent goes back thousands of years. Scientists believe that people from Asia crossed over to Alaska more than 20,000 years ago and then moved southward. Their descendants eventually established great civilizatiions, such as that of the Maya in Central America and Aztec in Mexico. The first Europeans in the regions were the Vikings, who settled in Greenland in about the 900s. It wasn't until 1492 that explorers from other parts of Europe began to arrive.
