Tectonic plates are the surface of each and every thing on earth. all land forms rest upon them. When the plates shift, so does everything above it. But one thing is that you can barely notice it, approx. 1 inch year
Australia is an island country, and besides the big main island and Tasmania, it has 12,000 islands plus in its territory. Since it doesn't have any land borders, its borderline is actually the sum of all coastlines of all islands in its territory, and that accounts for 70,000 km.
New South Wales is the biggest state in the country, and it occupies 10% of its total land mass. Its border is 4,635 km, which means that it accounts for 6.62% of the total borderline of Australia.
Mains primary land cover is trees.
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
