Use the steps below to determine the of CO2 stored or released in an acre of forest. Calculations: 1. (5 points) Calculate the average biomass per 100 m2 (10m x 10m plot) for the three plots in the Biomass Table. Thus average biomass per 100 m2 = _7735.25_ kg/100 m2 (Hint: add the total biomass for each of the 3 plots and then divide by 3) 2. (5 points) For this question, convert biomass per m2 to biomass per acre. Since 1 acre = 4047 m2 , multiply the average biomass per 100 m2 by ...

(5 points) For this question, convert biomass per m2 to biomass per acre. Since 1 acre = 4047 m2 , multiply the average biomass per 100 m2 by 40.47. Thus average biomass per acre = _313,045.57 kg/acre (Hint: multiply your answer in (a) by 40...

Which of the following mining processes removes the top layers of soil, rock, and vegetation to access minerals?  A. Acid mine drainage  B. Subsurface mining  C. Smelting  D. Surface mining Answer Key: D Feedback: Surface mining removes surface vegetation, rocks, and soil to create an open pit for mining. Subsurface mining uses vertical or sloping shafts to access minerals deep underground. Smelting melts ore to separate valuable minerals from impurities. Acid mine drain...
