Answer:
Dead Zones
Explanation:
Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes, caused by "excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water.
Answer:
Seafloor spreading occurs at Feature A and subduction occurs at Feature B
Explanation:
On the image we can see two contrasting features. One of them gives rise to the new crust, while the other destroys the old one. Feature A is a mid-ocean ridge. This is the place where there's a divergent plate boundary. The gap left behind the plates that move away is filled with magma, which constantly piles up new layers that are becoming new crust. It is hear where the ocean floor is spreading. Feature B is the opposite, it is a subduction zone. In the subduction zones, one of the plates moves below the other plate, reaching the mantle layer, getting melted and destroyed. On the place of the boundary, there's a deep valley that forms in the gap, known as an ocean trench.
Answer and Explanation:
1. Sub-Saharan Africa has a very strong economic dependency, which means that its population has less access to education and resources. The limitation of resources prevents the population from having full access to contraceptive methods that can limit the exacerbated growth of the population that did not have a structure that shelters it efficiently. In addition, deprivation of sex education has prevented families from learning concepts about contraceptive methods, family planning, among others that promote rational population growth. This all contributes to Sub-Saharan Africa's population growth, which is increasingly disproportionate and growing, compared to the rest of the world.
2. The two groups differ in their projections of population growth, because they make analyzes using different factors, at different intensities. This is because the projection of population growth is a subjunctive factor, which has countless variables and can have different analyzes and interpretations.
B) Earths rotation, geothermal activity, gravitational forces
