Answer:
c. Lack of food sources
Explanation:
The groundwater has been used more and more around the world. There are large reserves of it, but in the past few decades the groundwater reserves have constantly been going down. The main reason for this is the lack of food sources. Because the global population is constantly on the rise, more and more food is needed, and in order to produce it, more and more farmlands are created. The increased number of farmlands means that more water is needed for irrigation, thus the groundwater reserves are the ones that suffer the most.
Answer:

Densidade Demográfica no Mundo
De acordo com um estudo realizado pela Organização das Nações Unidas (ONU), a população global atual é de 7,6 bilhões de habitantes. Devido a isso, estima-se que a densidade demográfica no mundo gira em torno de 50,66 habitantes/km² considerando apenas as extensão terrestre do planeta de 150 milhões de km².
Entretanto, assim como acontece no Brasil, esse valor não é representativo e por isso há regiões com densidades superiores e inferiores a média global.
Answer:
volcanoes most common in subduction zones between oceanic and continental plates
Explanation:
- Plate boundaries are share and thin sheets of slabs over the surface of the earth and these boundaries are demarcated by the ridges and trenches and interplate margins as the plate tends to move in the opposite direction to the forces of friction and the pushing and pulling nature of the rock from the mantle below crates a dynamic force that created most volcanoes.
- The impact of these zones like the fault line and the lines that divide the plate margins tends to fall into a deep zone full of trenches and cavities that leads to the burning of the plate matter and the rising current then pushes this upwards and hence result is volcanic eruption due to the heat and pressure build inside.
