Answer:
Deep-sea trenches generally lie seaward of and parallel to adjacent island arcs or mountain ranges of the continental margins. They are closely associated with and found in subduction zones—that is, locations where a lithospheric plate bearing oceanic crust slides down into the upper mantle under the force of gravity.
Explanation:
"The result is a topographic depression where the oceanic plate comes in contact with the overriding plate, which may be either oceanic or continental. If the overriding plate is oceanic, an island arc develops. The trench forms an arc in plan view, and islands with explosive volcanoes develop on the overriding plate. If the overriding plate is continental, a marginal trench forms where the topographic depression appears to follow the outline of the continental margin. Explosive volcanoes are found there too"
Maybe Mr. Mittiga would know the answer? Or Mr. C?
B.All continental coastlines have high availability of wind power
No, as more people exit the window of fertility (some of whom without children) their life begins to become more dependent on other people. At first it will be small things, but as people reach their 80s, care homes are usually the only place for them. An elderly population means that younger skilled workers are more likely to leave, as they are less inspired in an ageing economy, and they take their talent with them. It leads to population decline, negligence of many industries and almost would have to be supported by a governmental health program. This is why many view immigration as a good thing. As younger people from poorer countries are attracted to high salaries and freedoms, they produce children and begin to fill some of the gaps in birth rate. However, this ultimately leads to cultural dilution in the host country, which many (especially the old) don’t want.
