The correct answer is letter <span>d. none of the above. The choices presented are possible cause of soil erosion. Soil erosion happens when a big boulder of rocks and soils coming from a mountain slide down because of external forces just like water (specifically during heavy rains), gravity, and as well as burrowing animals.</span>
Erosion is a process in which there is gradual wearing away of the earth surface by the action of natural elements such as water, wind, glacial ice and gravity. Burrowing animals, gravity and water are all possible cause of erosion. Burrowing animals are animals that create a hole or tunnel in the ground to provide suitable habitat or a byproduct of movement. The foot of hard-footed animals such as cattle and horses can create hole in the ground when the animals are walking. This makes the soil to become soft. Water or wind can erode the soil by transporting it to another location.
Explanation: Newton’s Law. The more mass two objects have, the greater the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled.
