A map shows areas of insolation (incoming solar radiation) across the world, categorized by watts per square meter.

Average annual levels of solar radiation reaching the Earth's surface

Insolation

The map illustrates global insolation, showing variations in incoming solar radiation from the tropics to the polar regions. In the Northern Hemisphere, high insolation (220 to 280 plus watts per square meter), highlighted as dark green to dark red spans from northwestern Mexico through southern Texas, Florida, and the Caribbean, across the Atlantic to North Africa and Southwest Asia, with peaks in the eastern Sahara and Arabian Peninsula. In the Southern Hemisphere, high insolation areas stretch from East Africa to South Africa and across the Indian Ocean to most of Australia, with other high insolation zones in the Central Pacific and south-central South America. Middle insolation values (120 to 219 watts per square meter), highlighted as light blue to green, are found between 50 degrees north and 50 degrees south latitude, excluding high insolation regions. Low insolation areas (80 to 119 watts per square meter), highlighted as blue to light blue, are located north of the 50-degree lines to the poles in North America, the North Atlantic, and Eurasia, and around the Southern Ocean in Antarctica. The lowest insolation values (less than 80 watts per square meter), highlighted as dark blue, are in the ocean east of northern Greenland.

A world map shows tectonic hotspots around the globe, marked with red dots. High concentrations of hotspots are found along the Mid-Atlantic Ridge, the Pacific Ring of Fire. Areas with fewer hotspots include Europe, Asia, and Australia.

Locations of tectonic hotspots—areas in the mantle where heat rises as a thermal plume from deep in the Earth.

Tectonic Hotspots

In North America, prominent hotspots are concentrated along the western United States, including the states of California, Oregon, and Washington, extending into Alaska. Additional hotspots are found in the Gulf of California, and in Central America, especially in Mexico and Guatemala. The Atlantic Ocean features multiple hotspots, notably near the Mid-Atlantic Ridge. Africa's hotspots are primarily situated along the East African Rift, particularly in Ethiopia, Kenya, and Tanzania, with others scattered across the continent, including Nigeria and Algeria. The Indian Ocean hosts several hotspots, especially near Madagascar and the Seychelles. In Europe, hotspots are visible in Iceland, France, and Spain. Asia's tectonic activity is concentrated in Vietnam and Cambodia. The western part of the Arabian Peninsula, particularly Saudi Arabia, also shows considerable tectonic activity. The regions of Mongolia and Japan show numerous tectonic hotspots. The map also shows hotspots in the South Pacific Ocean, near New Zealand and various island nations.
