Answer:
The correct option is: 2,250,000 kg
Explanation:
Given
: Area A = 1 ha (Hectare) = 10,000 m²
Bulk density = 1.5 Mg/m³ = 1.5 × 1000 kg/m³ = 1500 kg/m³ (∵ 1 Mg=1000 kg)
Depth of soil = 15 cm = 0.15 m (∵ 1 m = 100 cm)
Volume can be calculated by:
Volume = area × Depth = 10,000 m² × 0.15 m = 1500 m³
As we know, density = mass/ volume
Therefore, <u>Mass of soil</u> = Bulk density × volume = 1500 kg/m³ × 1500 m³ = 2,250,000 kg

Answer:
<u>Greenland Norse collapse</u>
Explanation:
- The southern Greenland Vikings numbering 5000 at their peak never gave up their old way of lifestyle and did not adopt that of the Northern Inuits who arrived a century later after them.
- The study suspects that the climate factors became dominant and they were destroyed by the shifting nature of mother earth hence they starved to death and could not adapt to the present change in weather patterns this society collapsed.
- Some theories say soil grazing and over-exploitation of land lead to the effect of black deaths and the creation of ice age. It indicated that the number of fertile women dropped and thus population could not sustain itself.
