Answer:
bulk density = 1400 kg/m³
bulk density after compaction = 1750 kg/m³
Explanation:
given data
volume = 0.5 m³
porosity = 40%
oven-dry weight = 700 kg
reduce the total porosity = 20%
to find out
bulk density and bulk density after compaction
solution
we know bulk density formula that is
bulk density = 
...............................1
put here value we get
bulk density = 
bulk density = 1400 kg/m³
and
if porosity decrease 20 % that mean volume change
so total volume = 0.5 
total volume = 0.4 m³
so bulk density after compaction is from equation 1
bulk density = 
bulk density after compaction = 1750 kg/m³
The early European exploration of Australia's interior was prevented by the Western Plateau and the Great Dividing Range.
Explanation:
Australia was discovered and explored by the Europeans much latter than the other large land masses on the planet, apart from Antarctica of course. When Australia was discovered, it was not inhabited, but it was after some time when the British came that Europeans started to settle in. Australia was actually used as a prison, as it is mostly British prisoners that were brought and settled.
It was only the coastal areas that were explored and settled though, while the interior was left untouched. The reason for this were the natural obstacles, mainly the Great Dividing Range and the Western Plateau. The Great Dividing Range is a high and steep mountain range, covered with dense forest, in a roughly north-south direction, and it was extremely hard and dangerous to pass it. The Western Plateau is an enormous plateau that is mostly covered with deserts, so naturally the people avoided it.
Even nowadays, there is very big portion of Australia that is not explored and is void of humans, such as:
- Great Victoria Desert
- Great Artesian Basin
- The tropical rainforest in the northeast
- Macdonnel Ranges
