Question

which of the following is not considered a factor in soil formation?
climate
parent material
ocean currents
time
a marble statue in a warm wet city becomes rough and pitted after years of acid
rain
name the weathering type and the specific chemical process. explain in one
sentence why that climate speeds it up.
your answer
which of the following best describes the slow downhill movement of soil
over time?
creep
landslide
mudflow
rockfall

Explanation:

Step1: Determine the weathering type

The weathering type is chemical weathering.

Step2: Identify the specific chemical process

The specific chemical process is carbonation. Marble (calcium carbonate) reacts with acidic rain (which contains carbonic acid). The reaction is \(CaCO_{3}+H_{2}CO_{3}
ightarrow Ca(HCO_{3})_{2}\).

Step3: Explain why warm - wet climate speeds it up

In a warm - wet climate, there is more water (for the reaction) and higher temperatures (increase the reaction rate as per the Arrhenius equation \(k = A e^{-\frac{E_{a}}{RT}}\), where \(k\) is the rate constant, \(R\) is the gas constant, \(T\) is temperature, \(E_{a}\) is activation energy and \(A\) is pre - exponential factor). Higher \(T\) leads to higher \(k\), i.e., faster reaction.

Answer:

Chemical weathering, carbonation. Warm - wet climate provides more water and higher temperatures (increase reaction rate) for the chemical reaction.
