Answer: True
Explanation:
Eutrophication is a natural phenomena, in this the fertilizers which are rich in concentration of nitrogen and phosphorus due to the effect of surface runoff get deposited in the nearby water body such as river, lake, pond and others. These fertilizers facilitate the growth of aquatic plants in the water body. The excess growth of plants reduces the oxygen content of the water body, which results in decline in the population of aquatic animals and foul smell in water.
Answer:Evaporation over the oceans supplies the water molecules that support precipitation over land. These circulation patterns are in large part driven by energy differences ... The yearly average temperature of the Northern Hemisphere is approximately ... Hemisphere and Southern Hemisphere for winter, summer and the year.

Answer:
Options (A), (C), (D) and (E)
Explanation:
The tectonic setting usually refers to the plate tectonic activity, where the earth's crust is divided into numerous small and large plates that move over the layer of the asthenosphere. This motion of plates gave rise to the formation of different geological settings on and under the earth's surface.
Some of the common tectonic activities that are associated with the volcanic activity are as follows-
- Continental rift refers to the splitting of the continental areas, where the rift valley is formed eventually and due to this divergent motion of the crust, there form volcanoes in the adjacent side of the plate boundary.
- Mantle plumes refer to the region where the hot and less dense magma rises up from the interior of the earth, forming large convection cells in columns. When plates move over this region, there form volcanoes. For example, Hawaii.
- Island arcs and continental arcs are commonly formed in the convergent plate boundaries, where the subduction zone is formed and as the magma rises upwards towards the surface in the over-riding plate, it forms volcanoes.
Thus, the correct answers are options (A), (C), (D) and (E).
