A map illustrates areas at risk of soil degradation worldwide, categorized by serious concern, some concern, stable terrain, and non-vegetated land.

Levels of concern for there to be a decline in soil quality caused by its improper use, usually for agricultural, pastoral, industrial, or urban purposes.

Areas at Risk of Soil Degradation

The map shows areas at risk of soil degradation using different colors. Areas of Serious Concern (light pink): North America: Great Plains, southwestern deserts, and Mississippi Valley. Central America: Most of the land. South America: Lands along the Andes mountains, parts of interior and coastal Brazil. Europe: Mostly in Eastern Europe. Africa: Near the Mediterranean in North Africa; lands of the Sahel along the southern border of the Sahara; in and around Nigeria in West Africa; the island of Madagascar; smaller patches in East Africa and southern Africa. Asia: Central and eastern China, much of mainland Southeast Asia, the islands of Borneo, and the Philippines. Australia: Southeast Australia has a small area of serious concern. Areas of Some Concern (light purple): Found in scattered regions across North America, South America, Europe, Africa, and Asia. Stable Terrain (light blue): These areas include parts of North America mostly in Canada, South America in parts of Brazil, and in parts of Europe, Africa, and Asia. Nonvegetated Land (dark blue): Predominantly in desert regions such as the Sahara, Central Asia, and parts of Australia.

Geosystems: Intro to Physical Geography

Map of global ocean circulation sinks, marked by blue circles. Key sinks are located in the North Atlantic (near Greenland and Labrador Sea) and in the Southern Ocean (Weddell Sea near Antarctica).

Circulation sinks are source areas for deep water in high-latitude regions where surface water cools, increases in density, and sinks.
