The wholesale removal of sediment by wind is called:

The wholesale removal of sediment by wind is called deflation.

Explanation:

Deflation is the phenomenon of displacement of small particles, seeds and other finer grains by wind. The materials which are carried and deposited are called the sediment.

In areas where deflation occurs, only big rocks are visible. The only fine particles of materials are hidden by these big rocks.

Desert pavements are the result of deflation. Desert pavements consist of big rocks and other solid fragments since smaller fragments have been eroded in deflation. The fragments left behind remain consistent hence, desert pavements remain stable over time.

a is the answer i believe.

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.
