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.

The correct answer is D. Decreased travel times.
The industrial revolution revolutionized the transport as well, so in this period we have the emergence of transporting machines, like the trains for example, and they were also getting better and better as the year passed by, and they were of great help to the people, especially when they had to travel on long distances.
Answer:
Explanation:
It helps in assessing the level of pollution in relation to the air quality standards. Standards are a measure to set the target for pollution reduction and achieve clean air.
Answer:
Explanation:
So we can use them for further research in the future
