A map illustrates the global distribution of carbonate rock outcrops, indicated by yellow dots across various continents.

Locations of outcrops of carbonate rocks, primarily limestone and dolostone

Carbonate Outcrops

In North America, outcrops are prevalent along the western coast, the southeastern United States, and parts of Mexico. Central America and the Caribbean also have notable concentrations, particularly in Costa Rica and Cuba. In South America, significant outcrops are found in Venezuela, Peru, Bolivia, Brazil, and Paraguay. Europe shows widespread outcrops, especially in France, Spain, Poland, and Ukraine, with additional dots in the United Kingdom and Sweden. Africa has notable outcrops in Morocco, Algeria, Nigeria, Cameroon, Gabon, the Democratic Republic of Congo, Angola, Zambia, Zimbabwe, and South Africa. In Asia, outcrops are concentrated in Turkey, Iran, Pakistan, India, Nepal, Sri Lanka, Myanmar, Vietnam, Cambodia, Malaysia, Indonesia, and the Philippines, with additional dots in China, Mongolia, and Russia. Southeast Asia has numerous outcrops, particularly in Indonesia. In Australia, outcrops are found along the eastern coast and in southern Australia, with additional dots in New Zealand.

A world map shows water resources vulnerability.

Measure of projected water stress in the year 2020; water stress is the ratio of total annual water withdrawals to total available annual renewable supply.

Water Resources Vulnerability

Areas shaded in light yellow represent regions with arid and low water use, predominantly found in parts of Australia (central regions), Egypt, Saudi Arabia, Libya, Mauritania, and Yemen. Regions with low vulnerability, less than 10 percent, are shown in light orange and are primarily located in most parts of Africa, South America, Canada, Russia, most of Asia. Areas with low-medium vulnerability, ranging from 10 to 20 percent, are depicted in orange and are scattered throughout some parts of Japan and U S A, some parts of Asia and Europe. Medium-high vulnerability areas, between 20 to 40 percent, are shown in light red and are mainly found in South Africa, China, and many more. High vulnerability regions, ranging from 40 to 80 percent, are shaded in red and are located in parts of U S A, Europe, and Asia. Areas with extremely high vulnerability, over 80 percent, are shown in dark red and include most of U S A and Asia. Some areas such as Greenland and South Pole are marked with a gray shade, indicating no data available for those regions.

The map shows that in most counties in the United States, the median age is between 33 and 42 years. However, there are several regions where the median age is higher, and there are also scattered counties where the median age is lower. In the eastern United States, most states are mainly between 33 and 42 years. In the Northeast, counties with a median age between 43 and 52 years occur in northern New York, northern Maine, rural New England, and parts of Pennsylvania. In the South, counties between 43 and 52 years are found in western Virginia, the southern Appalachian mountains, northern Arkansas, and Florida. The latter also has several counties between 53 and 63 years. In the Midwest, the median age is between 43 and 52 years in counties in northern parts of Michigan, Wisconsin, and Minnesota, as well as in Iowa, and to a lesser extent, in Missouri. States in the northern Great Plains (North and South Dakota and Nebraska) have numeroCounties between 43 and 52 years. At the same time, South Dakota has several counties that are younger, between 22 and 32 years. The northern Rocky Mountain states (central and northern Idaho and Montana) have more counties between 43 and 52 years than between 33 and 42 years. States farther south—Wyoming, Colorado, and New Mexico—are younger, with most counties between 33 and 42 years. New Mexico also has two counties between 53 and 63 years. Northern Utah, northeastern Arizona, and southern Idaho have younger median ages, with counties between 22 and 32 years. Southeastern Arizona and Nevada are between 33 and 52 years, with one county in southeastern Arizona between 53 and 63 years. Along the Pacific Coast, most counties are between 33 and 52 years. Exceptions include one coastal county each in Oregon and Washington that is between 53 and 63 years; an area in eastern Washington that is 22 to 32 years; and much of California’s Central Valley and inland counties from the San Francisco Bay area southward, where the median age is between 27 and 32 years. Hawaii’s median age is between 22 and 42 years. Most of Alaska’s median age is between 33 and 42 years, except along the western side of the state, where median ages are between 22 and 32 years, and parts of the panhandle, which are between 43 and 52 years.
