Questions & Step-by-Step Solutions

If the soil erosion rate in a river basin is 2 tons per hectare per year, how much soil will be eroded from a 50-hectare area in 5 years? (2023)
  • Step 1: Identify the soil erosion rate, which is 2 tons per hectare per year.
  • Step 2: Identify the area of land, which is 50 hectares.
  • Step 3: Identify the time period, which is 5 years.
  • Step 4: Calculate the total soil eroded by multiplying the erosion rate by the area and the time: 2 tons/hectare/year × 50 hectares × 5 years.
  • Step 5: Perform the multiplication: 2 × 50 = 100 tons per year.
  • Step 6: Now multiply the result by the number of years: 100 tons/year × 5 years = 500 tons.
  • Step 7: The total soil eroded from the 50-hectare area in 5 years is 500 tons.
  • Soil Erosion Calculation – This question tests the ability to calculate total soil erosion over a specified area and time using a given rate.
