81 On the grid in your answer booklet, construct a profile of the thickness of the volcanic ash deposits by

plotting the ash fall along line AB. Plot each point where an isoline showing thickness is crossed by line AB.

Ash thickness at location A has been plotted. Complete the profile by connecting all seven plots with a line. [

]

82 Identify the atmospheric layer within which most of the volcanic ash was transported. [

]

83 Describe one way the volcanic ash cloud may have contributed to cooler weather conditions in Europe. [

]

84 The graphs below indicate the percent by mass of different diameters of ash particles deposited at

2 kilometers and 60 kilometers from the volcanic eruption.

Describe how the size of the deposited ash particles changed with increased distance from the volcano. [
