Question
Chapter 2, Problem 2.1P
(a)
To determine
Whether the statement “Aeolian soils are transported and deposited by wind” is true or false.
(a)
Expert Solution
Answer to Problem 2.1P
The statement “Aeolian soils are transported and deposited by wind” is true.
Explanation of Solution
- • The classification of soil is based on the transportation. Aeolian soils consist of sand or silt sized particles.
- • This type of soil is normally transferred from one place to another place through the wind. Soils are divided into groups based on their mode of transportation.
Hence, the statement is True.
(b)
To determine
Whether the statement “Marble is an igneous rock” is true or false.
(b)
Expert Solution
Answer to Problem 2.1P
The statement “Marble is an igneous rock” is false.
Explanation of Solution
- • Marble is a metamorphic rock that forms when limestone is subjected to heat and pressure from all sides.so, marble are not classified as an igneous rock.
Hence, the statement is False.
(c)
To determine
Whether the statement “Sandstone is a sedimentary rock” is true or false.
(c)
Expert Solution
Answer to Problem 2.1P
The statement “Sandstone is a sedimentary rock” is true.
Explanation of Solution
- • Sandstone is a clastic sedimentary rock.
- • It’s composed of rock, organic material, and sand size grains of mineral.
Hence, the statement is True.
(d)
To determine
Whether the statement “Silts have no plasticity” is true or false.
(d)
Expert Solution
Answer to Problem 2.1P
The statement “Silts have no plasticity” is true.
Explanation of Solution
- • It is termed as very fine particles of sand, and it is carried by moving water and deposited as sediment.
- • The particles of silt are very fine and it does not have plasticity at all.
Hence, the statement is True.

Consider, M people (aka pax) who want to travel by car from O to D. They all start working at
D at Q (e.g., Q-8am). If a person departs at time t, assume the time needed to go from O to D
is given by c(t)=A+Bx(t), where x(t) is the flow of people departing at time t [car/unit of time].
In addition, a is the penalty for being early at work (E(t) is how early the person arrived when
departing at time t), and ẞ is the penalty for being late at work (L(t) is how late the person
arrived when departing at time t). Assume 0 < a < 1 < ß. Further assume the departure time
choice problem under the equilibrium conditions. Prove that the arrival time of people who
depart when most of the M people start their trips is equal to Q.
