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 possibly increase or decrease as slope angle is lessened, depending upon other factors.
B)It is not affected by the slope angle.
C)It will decrease as the slope angle is lessened.
D)It will increase as the slope angle is lessened.

The gravitational force pulling the particle downward along the slope is directly related to the slope angle; as the slope angle decreases, the component of gravitational force acting along the slope also decreases, leading to a reduced pull on the particle in the direction of the slope.
