Age of the bedrock underlying North America, from red (oldest) to blue, green, yellow (newest). Seventy percent of North America is underlain by the Laurentia craton, [5] which is exposed as the Canadian Shield in much of central and eastern Canada around the Hudson Bay, and as far south as the U.S. states of Michigan, Wisconsin, and Minnesota.
In continental climates, precipitation tends to be moderate in amount, concentrated mostly in the warmer months. Only a few areas—in the mountains of the Pacific Northwest of North America and in Iran, northern Iraq, adjacent Turkey, Afghanistan, Pakistan, and Central Asia—show a winter maximum in precipitation. A portion of the annual ...
The Gulf and South Atlantic states have a humid subtropical climate with mostly mild winters and hot, humid summers. Most of the Florida peninsula including Tampa and Jacksonville, along with other coastal cities like Houston, New Orleans, Savannah, Charleston and Wilmington all have average summer highs from near 90 to the lower 90s F, and lows generally from 70 to 75 °F (21 to 24 °C ...
A map of North America's physical, political, and population characteristics as of 2018. North America is a continent [b] in the Northern and Western Hemispheres. [c] North America is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean.
Within North America, moisture within this climate regime is supplied by the Great Lakes, Gulf of Mexico and adjacent western subtropical Atlantic. [8] Precipitation is relatively well distributed year-round in many areas with this climate (f), while others may see a marked reduction in wintry precipitation, [6] which increases the chances of a wintertime drought (w).

The U.S. climate is temperate in most areas, tropical in Hawaii and southern Florida, polar in Alaska, semiarid in the Great Plains west of the 100th meridian, Mediterranean in coastal California and arid in the Great Basin. Its comparatively generous climate contributed (in part) to the country's rise as a world power, with infrequent severe ...
In 1931 Thornthwaite published “The Climates of North America: According to a New Classification”, [8] which launched his career as a climatologist and married the science of climatology with that of geography. The article and the classification were inspired by the Köppen climate classification system. Thornthwaite learned about the ...
These climates are most often located between the Equator and 25 north and south latitude. A monsoon is a seasonal prevailing wind which lasts for several months, ushering in a region's rainy season. [9] Regions within North America, South America, Sub-Saharan Africa, Australia and East Asia are monsoon regimes. [10] The world's cloudy and ...
