Question

A force that slowly wears away mountains and other features on the surface of Earth is. . . . a..constructive. . b. destructive. .c. superposition. d. unnatural .

Answer 1

Answer:

The answer is b (destructive)

Explanation:

There are 2 types of destructive forces that wear away mountains and other features:

• Slow forces

The 2 main destructive forces that wear down mountains and land features of the earth slowly and steadily are weathering and erosion. Weathering is the breaking down of rocks due to forces such as wind and water. The pieces of rock are then moved elsewhere through the process of erosion. The classic examples of weathering and erosion are The Grand Canyon and Monument Valley in Arizona.  

• Quick forces

Quick destructive forces are earthquake and tsunami that can eliminate the features of our Earth in minutes or even in seconds. Tsunami can smooth the Earth surface and erase hills and mountains. A tsunami can take hundreds of km of Earth and drag it back to the ocean floor. Earthquake can cause the Earth to crack, causing sinkholes. Quick destructive force can also be a landslide. Mountain sides can move to the base of a mountain in seconds.

Answer 2

The answer is destructive force. 
Constructive force is the force that makes or forms the mountains and other features. Superposition forces are topics to be discussed in theories in physics and systems and may not be applicable here. Unnatural is just an unusual choice.
