“The number of miles we walked (for the last Census was) astronomical,” said Robert Colosi, special assistant to the chief of the Decennial Statistical Studies Division. “We’re not going to do that in 2020.”
Answer:
D
Explanation:
Erosion is when rock is broken or loosed by wind, water, or other means
Creep is the slow downslope movement of particles that occurs on every slope covered with loose, weathered material.
Slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope.
Deposition is a process in which sediments, soil and rocks are added to a landform or land mass.
10.2 hours is equivalent to three half-lives, so after 10.2 hours, the mass of the sample would have decayed by half three times over. If one starts with 100 mg of the sample, then after three half-lives, there would be 100(0.5)³ = 12.5 mg of the sample remaining.
Thus, the correct answer choice here would be D.
