Humans can disrupt the ecosystem by for an example drilling under the ground so you can find oil well that is bad because it increases having more earthquakes.
Answer:
- Divergent plate boundary, which causes volcanic activity and shallow earthquakes.
- Convergent plate boundary, which has one plate that “dives (‘subducts’) beneath the other, resulting in a variety of earthquakes and a line of volcanos on the overriding plate”
- Transform plate boundary, where plates slide laterally past one another, producing shallow earthquakes but little to no volcanic activity.
- Hotspot, “where a plate rides over a rising plume of hot mantle, creating a line of volcanoes on top of the plate.”
Folk culture is more likely to have an anonymous origin and to diffuse slowly through migration, whereas popular culture is more likely to be invented and diffuse rapidly with the use of modern communication.
A net population decline resulting from an "excess of deaths over births".
Option: A
<u>Explanation</u>:
Demographic transition is a shift from higher to lower level of fertility and mortality.Rapid development in industrialization and urbanization in 
century resulted into enormous population growth. But decline in early 
century covered many reasons like consequences of two calamitous wars, where Europe suffered large population declination due to battle death and civilian causalities in World War I and II. Hence the acceleration of population growth in 19th century but downfall in 20th is also considered as balance.
