Which force causes mass movements? a. chemicals b. waves c. wind d. gravity

The correct answer is option D. Gravity.

Explanation:

Mass movement is mainly caused by the force of gravity.

We can find this kind of force in all the parts that make up the earth's surface.

If an object is on a flat surface, which is on par with the surface of the Earth, the force of gravity will "pull it down." This is what holds us to the ground and prevents us from gravity affecting us. As long as we remain on the flat surface, we will not move down. But if somehow the surface where we are standing weakens or fails, the support mass will fall down.

d. stage 4

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]

all fossil fuels are nonrenewable, so think coal, gasoline, things that we will eventually run out of. all fossil fuels are nonrenewable resources, but not all nonrenewable recourses are fossil fuels. these resources are not being renewed as fast as we are using them. i hope this considering there weren't any answer choices.
