Answer:
Siltation
Explanation:
As you already saw in the question above, gravity can cause soil erosion and cause sediments from eroded soil to accumulate on the bottom of rivers, causing siltation.
The silting up causes sediments to accumulate at the bottom of the rivers, causing an increase in the riverbed. This causes the river to have an elevated bed and can cause flooding.
To avoid silting up, it is important that the riverside has vegetation capable of containing these sediments and preventing it from accumulating at the bottom of the rivers.
Answer:
Group A has a greater gravitational force.
Explanation:
According to Newton's Law of Universal Gravitation. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
