Gce Model Questions Vol1 2018 Geography Question 4
Practice objective / multiple choice question 4 from the 2018 Gce Model Questions Vol1 Geography examination.
A 1000 kg sample of sedimentary rock consists of 40 % quartz, 30 % calcite, 20 % feldspar and 10 % clay by mass. Densities are: quartz 2.65 g cm⁻³, calcite 2.71 g cm⁻³, feldspar 2.55 g cm⁻³, clay 2.30 g cm⁻³. During metamorphism, quartz and feldspar retain their densities, calcite transforms to marble (density 2.70 g cm⁻³) and clay transforms to mica (density 2.80 g cm⁻³). Assuming mass of each component is conserved, what percentage of the total volume of the metamorphosed rock is occupied by mica? Give your answer to one decimal place.
