Why does the equatorward bending of height contours for the 500 mb level imply the presence of a trough?

Geography

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.

Stels [109]

The Forestry Department is using a <u>chemical</u> control method. This involves using a <u>foliar spray </u>method, in which department personnel will spray pesticide directly on the trees’ leaves.

Explanation:

The chemical control method of pesticide control involves spraying chemical pesticides directly on leaves, shoots or roots of the plants. These chemicals are toxic to the pests only and the pests get retracted from the plants because of the pesticides applied.

A selective pesticide application is done to limit application to a target harmful pest which kills only that and does not harm the other useful or harmless species which thrives on the plants.

White pine blister causes rust of the branches and leaves of the pine trees. Hence, a foliar spray of the pesticide is done to control its spread.
