Europe and Asia are in the same landmass, like you can see in this picture.
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.

East Asia's coastal, island and peninsula area are similar as they lie on the Ring of Fire. Accordingly, every one of these territories has tremors and volcanoes. Be that as it may, they additionally have hot springs. These ranges are unique in relation to inland regions due to the elevation: the island is more tough and rocky than the beach front, island and promontory zones.
