I've had the same question, the answer is longitude.
Answer:
A. is a gravity-driven downslope movement of natural materials.
Explanation:
Mass movement -
It is also called , the slope movement , mass wasting .
it is a process , by which , the sand , rock , soil , regolith move towards downslope by the force of gravity .
It includes , slides , falls , topples , creep .
Mass movement is observed in planets other than Earth , like the Mars , Jupiter , Venus .
Hence , from the given option , the correct option for the definition of Mass movement is ( A ) .
Answer:
The resistance of the air would be your answer.
Explanation:
It acts like same as Friction.
Hope it helps!
A Landslide is a type of mass movement that occurs when a thin block of soil, rock, and debris separates from the underlying bedrock.
Actually, this thin block of soil and rocks were held by Tree's roots so it do not separated from the bedrock. Now days, more and more trees were cutted down for modern development, and more landslides happen because of this.
