<span>True. Contour lines are found on maps to determine equal elevation of connecting points. When a person walks along contour lines he neither gains nor loses elevation.
False. Relief does not refer to the height of an object above sea level. Mean Sea level determines the height of an object above sea level. <span>

Answer:
Wet unit weight = 1.94 g/cc
Dry unit weight =1.05 g/cc
density of saturation = 0.41
porosity = 0.43
Explanation:
given data
Void ratio = 0.78
Water content -12%
Specific gravity of solids - 2.68
to find out
Wet unit weight and Dry unit weight and Degree of saturation and Porosity
solution
we know that Wet unit weight formula is
Wet unit weight =
density of water
here Gs is specific gravity of soild and e is void ratio and density of water is 1
so Wet unit weight =
Wet unit weight = 1.94 g/cc
and
Dry unit weight =
density of water
Dry unit weight =
Dry unit weight =1.05 g/cc
and
density of saturation is
density of saturation = Wc × 
her Wc is water content
so density of saturation = 0.12 × 
density of saturation = 0.41
and
porosity is
porosity =
porosity =
porosity = 0.43
Due to erosion on the outside of a bend and deposition on the inside, the shape of a meander will change over a period of time.
Answer: Weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season. Climate, is the average of weather over time and space.
