A map shows wheat production in North America in metric tons. More than 5,000,000 is shaded dark red. 1,000,000 to 5,000,000 is shaded red. 100,000 to 1,000,000 is shaded orange. Less than 100,000 is shaded light orange.

A global map shows lightning flashes per square kilometer per year (flashes per square kilometer per year).

Lightning flashes per square kilometer per year (flashes/km²/year)

Lightning Frequency

The map illustrates global lightning frequency. Areas with less than 0.1 flashes per square kilometer per year are shaded in light green and include most ocean regions, northern Canada, the Sahara Desert, and parts of western and northern Europe. Areas with 0.1 flashes per square kilometer per year are shaded in light yellow and are scattered along parts of oceanic regions and coastal regions. Regions with 0.2 flashes per square kilometer per year are shaded in light purple and include parts of oceanic regions, coastal regions in the north of Canada and Russia. Areas with 0.4 flashes per square kilometer per year are shaded in red and are scattered along the Atlantic ocean, coastal regions on the north of Russia, Indian Ocean, and Pacific ocean. Areas with 0.6 flashes per square kilometer per year to 1 flash per square kilometer per year are shaded in blue to light green, covering northern Canada, the contiguous United States (excluding the Southeast), parts of South America, much of northern region of Europe, most of Africa south of the Sahara, and most of South, East, and Southeast Asia, including south of Australia. Areas experiencing 2 to 10 flashes per square kilometer per year, indicated by pink to blue shades, include the Southeastern United States, parts of Central and South America, and large areas in Africa, South, East, and Southeast Asia. High lightning frequency regions (20 to 50 flashes per square kilometer per year) are highlighted in dark pink to dark red, located in Southeastern United States, Colombia in South America, Central Africa (notably the Democratic Republic of Congo), and Southeast Asia, particularly in Indonesia, Vietnam, and Cambodia.

A map illustrates the distribution of calcium carbonate in modern surface sediments globally, with highest concentration found in the Caribbean, Mediterranean, and South Pacific and lowest concentration dominating the North Pacific, and Southern Ocean.

Percentage of ocean surface comprised of calcium carbonate.

Distribution of Calcium Carbonate in Modern Surface Sediments

The distribution is represented as a percentage by weight. Areas with the least calcium carbonate, ranging from 0 percent to 20 percent, are marked in very light blue and are prevalent in large parts of the Pacific Ocean, particularly around Samoa, the South Pacific, and parts of the Indian Ocean. Light blue regions, representing 20 percent to 40 percent calcium carbonate, cover parts of the North Atlantic Ocean, including areas around Cuba, the western coast of Africa near Senegal and Mauritania, and the southern Indian Ocean near Madagascar. Medium blue areas, indicating 40 percent to 60 percent calcium carbonate, include regions in the North Atlantic Ocean, off the coast of the United Kingdom and France, the Mediterranean Sea, parts of the Arabian Sea, and the South Pacific Ocean. Blue-green regions, with 60 to 80 percent calcium carbonate, are seen in the central Atlantic Ocean, areas around the Caribbean including Cuba and Guatemala, the western coast of Africa near Gabon and Angola, and the Indian Ocean. The highest concentration of calcium carbonate, 80 percent to 100 percent, marked in dark green, is found in regions of the North Atlantic Ocean, around the Bahamas and north of Cuba, parts of the South Atlantic Ocean near the eastern coast of South America, the central Pacific Ocean, and the northern Indian Ocean near Sri Lanka.
