The equatorward bending of height contours for the 500 mb level imply the presence of a trough because this represents a region of overall lower heights. A valley and a trough are hence equivalent in the upper air flow.
A trough is a linear structural depression with lateral length that occurs in geology. A trough can be a small basin or a natural rift, albeit it is lower than a trench. At the edge of tectonic plates, these landforms frequently form.
Trough, an extended depression in the seafloor that differs from oceanic trenches in that it is shallower, shorter, narrower, and topographically more mild. The Papuan Trough's maximum depth is 2,300 m (7,500 feet), while the Banda Trough's maximum depth is 7,440 m.

Prevailing winds are the planetary winds that are caused by the formation of giant convection cells over the earth. Prevailing winds blow from the hot regions of the earth, like the tropics, to the cold areas of the earth, like the temperate or polar regions, and from the cold areas back to the hotter regions.
I will say distance from the sea, ocean currents, direction of prevailing winds
Answer: sinking or rising
Explanation:
This band of bright clouds in the equatorial region is an indication of sinking or rising air. The band generally marks the locations where surface winds in the Northern and Southern Hemispheres blowing towards the equator meet. Called the ITCZ (Intertropical Convergence Zone), the band of cloudiness is characterized by the bright clouds indicating intense thunderstorm activity and by high rainfall rates. It roughly parallels the equator around the globe.
Answer:
People not having to work to feed themselves for the earth provided food in abundance.
