Consider a weathered rock or soil particle lying on a slope.How will the gravitational force pulling the particle downward along the land surface vary with the inclination of the slope?
A)It will increase as the slope angle is decreased.
B)It will decrease as the slope angle is decreased.
C)It is not affected by the slope angle.
D)It will decrease as the slope angle is increased.

Quizplus · Accepted Answer

The gravitational force is dependent on the weight of the particle and the angle of the slope. As the slope angle is decreased, the component of gravitational force pulling the particle along the land surface decreases, resulting in a decrease in overall gravitational force. Therefore, as the slope angle is decreased, the gravitational force pulling the particle downward also decreases.
