Published	09/15/2023	{{c1::True}} [T/F] Dry unit weight is greater than submerged unit weight.
Published	09/15/2023	{{c1::Sedimentary}} rocks are the weakest type of rock.
Published	09/15/2023	{{c1::Igneous}} rocks are the strongest type of rocks.
Published	09/15/2023	{{c1::Physical weathering}} is due to erosion, freezing & thawing, and exfoliation.
Published	09/15/2023	{{c1::Chemical weathering}} can be caused by hydration, oxidation, or carbonation.
Published	09/15/2023	Rocks can become {{c1::residual soil}} or {{c1::transported soil}}
Published	09/15/2023	There are {{c1::five}} types of transported soil. They are {{c1::alluvial, marine, glacial, colluvial, and aeolian/eolian soil}}
Published	09/15/2023	Alluvial soils are transported by {{c1::water}}.
Published	09/15/2023	Lacustrine soils are formed by deposition in {{c1::quiet lakes}}.
Published	09/15/2023	Colluvial soils accumulate at the {{c1::base of slopes and hills}} due to gravity.
Published	09/15/2023	Aeolian soils are transported by {{c1::wind}}.
Published	09/15/2023	What are the unique engineering qualities of alluvial soil?
Published	09/15/2023	A lower void ratio (e) means {{c1::denser}} soil.
Published	09/15/2023	Void ratio is always {{c1::greater}} than porosity.
Published	09/15/2023	In nature, porosity is around {{c1::20%-60}}%.
Published	09/15/2023	e = {{c1::1}}, n = {{c1::50%}}, S = {{c1::50%}}
Published	09/15/2023	The density of water is {{c1::1000kg/m3}}.
Published	09/15/2023	The density of waste is {{c1::700-1400kg/m3}}.
Published	09/15/2023	The density of concrete is {{c1::2300-2400kg/m3}}.
Published	09/15/2023	The density of soil is {{c1::1000-2400kg/m3}}.
Published	09/15/2023	What is the equation for degree of saturation? {{c1::S(%) = Vw/Vv*100%}}
Published	09/15/2023	Equation for density is {{c1::ρ=m/V}}.
Published	09/15/2023	The equation for unit weight is {{c1::γ=ρg=W/V}}.
Published	09/15/2023	what is the maximum void ratio for clean sand? {{c1::1.6emin}}
Published	09/15/2023	{{c1::False}}(T/F) Water can flow more easily through soil with a lower hydraulic conductivity.
Published	09/15/2023	{{c1::True}}(T/F) Larger the void ratio, larger the porosity.
Published	09/15/2023	{{c1::True}}(T/F) Higher the density, higher the unit weight.
Published	09/15/2023	{{c1::False}}(T/F) Higher the density, higher the void ratio.
New Card	09/19/2023	What is the hydrometer test do?{{c1::It is used to measure the smaller particles that cannot be differentiated from sieve analysis.}}
New Card	09/19/2023	What is Stoke's law? What is the equation?{{c1::Velocity is proportional to diameter of a particle}}{{c1::, where  }}
New Card	09/19/2023	What does well graded soil mean?{{c1::It has all ranges of soil types}}
New Card	09/19/2023	What is the risk with gap graded soil?{{c1::Internal erosion. Water gets into the gaps of the soil and there is a lack of stability.}}
New Card	09/19/2023	{{c1::Coefficient of uniformity}} and {{c1::coefficient of curvature}} quantify the grain size distribution.
New Card	09/19/2023	If Cu is greater than 4 and Cc is between 1-3, this is a {{c1::well-graded}} soil.
New Card	09/19/2023	If Cu is less than 4, this is a {{c1::poorly-graded}} soil.
New Card	09/19/2023	If more than 50% of the soil is made of sand and gravel, this is {{c1::coarse}} soil.
New Card	09/19/2023	If more than 50% of the soil is silt and clay, the soil is {{c1::fine}}.
