<span>In a volcano, you can observe a crack on the surface of the earth, from which molten lava comes out. The earth's crust basically breaks, and the high temperature and pressure melts the rocks present deep in the earth, which comes out during a volcanic eruption.</span>
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
Because the current from the estuary pushed the corals away before they could settle.
