“Which of the following is most likely caused by chemical weathering” A. cirques carved out by a melting glacier B. U-shaped valleys formed in a mountain region
C. Rocks and sediment transported and deposited
D. unrecognizable facial features on a marble statue

D. Unrecognizable facial features on a marble statue

Step-by-step explanation:

The first 3 answer choices are all examples of physical weathering, not chemical weathering.

This is because the changes were caused by natural things such as flowing water and heating.

However, unrecognizable facial features on a marble statue would be caused by chemical weathering, where chemicals can erode marble and cause distortion in a statue.

So, D is the correct answer.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
