Landslides, mudflow, slump and creep are all examples of
a. constructive force
c. mass movement
b. deconstructive force
d. none of the above

(C) Mass movement

Explanation:

 Mass movement is also known as slope movement and it is the geographical process in which the sand, soil and the rock moves towards the down slope under the force of gravitation.

The mass movement is one of the dangerous movement as it happened very quickly and it also involve the entire hill side areas. The frequency of the mass movement is generally characterized as the flow in the mud and the debris flows. The process of the mass movement are occurred continuously on the slope.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
