The answer to this question is True
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
1. The answer is B. the asthenosphere
Asthenosphere is a layer of the Earth situated below the lithosphere. It is a semi-fluid and ductile rock or partly molten rock. Due to semi-fluid state of asthenospheric rock, it behave like a plastic and flow gradually. Thus, causes movement of continents.
2. The answer is C. collision between tectonic plates
The Earth’s crust becomes unstable when tectonic plates meet. As the plates slide past each other and push against each other. This causes earthquakes and volcanic eruptions at the edge between the plates.
The answer is: Timber
Brazil has approximately around 3,500,000 square kilometers of forrest, which them had the potential to become the largest timber producers in the world. On average, The timber industry in Brazil produce around $ 73 Billion worth of products annually.
