A map highlights global income inequality measured by the G I N I index percentage. Countries shaded dark teal rate more than 50%. Countries shaded teal rate 40% to 50%. Countries shaded blue rate 30% to 39%. Countries shaded light blue rate less than 30%.

A map of income inequality as measured by the GINI index. A higher number represents higher levels of inequality.

A map highlights the principal aquifers across North America, categorized into three types.

Locations of various aquifers in North America, including consolidated rock aquifers, which are made up of mostly volcanic rocks in the Northwest and mostly sandstone and limestone elsewhere; combination aquifers, which are sand and gravel aquifers overlying productive rock aquifers; and productive aquifers, which have a 0.4 liter/second potential

Principal Aquifers

Consolidated rock aquifers, shaded in green, are predominantly found in northern Canada, including regions like Yukon, Northwest Territories, and Nunavut, and extending into parts of British Columbia, Alberta, Saskatchewan, Manitoba, and Newfoundland and Labrador. Also found in the northern Canada regions like Victoria Island, Parry Island, Canadian Arctic Archipelago, and Ellesmere Island, also extending to Southern regions like Winnipeg, Ottawa, and Halifax. Combination aquifers, shaded in orange, are primarily located in the central and eastern United States, covering areas in states like Texas, Oklahoma, Kansas, Nebraska, and South Dakota, and extending to parts of the Midwest, Northeast, and Southeast, including New York, Pennsylvania, and Florida. Productive aquifers, also shaded in light green, are found in regions of Florida and across the western United States near Oregon.

Geosystems: Intro to Physical Geography

Mean sea-surface temperatures shown using patterns of latitudinal bands extend roughly east to west. The coldest temperatures are shown in the northern latitudes. Temperatures warm as latitudes near the equator.

Average sea-surface temperatures between 1990 and 2020

Mean Sea-Surface Temperature

Sea-surface temperatures create latitudinal bands extending east to west, influenced by ocean currents and continents. In the tropics, temperatures range from 24.0 to 32.0 degrees Celsius; in the midlatitudes, from 8.0 to 23.9 degrees Celsius; and in higher latitudes and polar regions, from negative 2.0 to 7.9 degrees Celsius. Significant deviations occur along the Atlantic coast of western Europe, where temperatures are warmer than the east coast of North America at the same latitude, and along the Pacific coast of Canada, the Atlantic coasts of Canada and the northeastern United States, and the western coasts of South America and southern Africa, where waters are cooler than expected. The hottest ocean areas are between Indonesia and Australia (30.0 to 32.0 degrees Celsius), followed by tropical parts of the western Pacific and Indian oceans, and small areas along the coasts of West Africa and Central America (28.0 to 29.9 degrees Celsius).
