The ITCZ is visible as a band of clouds encircling Earth near the Equator. The Intertropical Convergence Zone ( ITCZ / ɪtʃ / ITCH, or ICZ ), [1] known by sailors as the doldrums [2] or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It encircles Earth near the ...
The Great Lakes tectonic zone (GLTZ) is bounded by South Dakota at its tip and heads northeast to south of Duluth, Minnesota, then heads east through northern Wisconsin, Marquette, Michigan, and then trends more northeasterly to skim the northernmost shores of lakes. Algoman orogeny added landmass to the Superior province by volcanic activity ...
The intaglios are located east of the Big Maria Mountains, about 15 miles (24 km) north of downtown Blythe, just west of U.S. Highway 95 near the Colorado River. The Blythe Intaglios are the most well-known of the over 200 intaglios in the Colorado Desert. [1] The Colorado Desert contains the only known desert intaglios in North America. [1]
The Nazca lines (/ ˈ n ɑː z k ə /, /-k ɑː / [1]) are a group of geoglyphs made in the soil of the Nazca Desert in southern Peru. [2] They were created between 500 BC and 500 AD by people making depressions or shallow incisions in the desert floor, removing pebbles and leaving different-colored dirt exposed. [ 3 ]
Rainband. A rainband is a cloud and precipitation structure associated with an area of rainfall which is significantly elongated. Rainbands in tropical cyclones can be either stratiform or convective and are curved in shape. They consist of showers and thunderstorms, and along with the eyewall and the eye, they make up a tropical cyclone.
Tropic of Capricorn. The Tropic of Capricorn (or the Southern Tropic) is the circle of latitude that contains the subsolar point at the December (or southern) solstice. It is thus the southernmost latitude where the Sun can be seen directly overhead. It also reaches 90 degrees below the horizon at solar midnight on the June Solstice.
A contour line (also isoline, isopleth, isoquant or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. [1] [2] It is a plane section of the three-dimensional graph of the function parallel to the -plane. More generally, a contour line for a function ...
Bathymetry ( / bəˈθɪmətri /; from Ancient Greek βαθύς (bathús) 'deep' and μέτρον (métron) 'measure') [1] [2] is the study of underwater depth of ocean floors ( seabed topography ), lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. The first recorded evidence of ...
