I. Divide the depth of the layer by the total depth. For example, to calculate the percentage of the total depth that the crust
represents, divide 40 by 6,046.
ii. Write your answer in the Percent column.
iii. Repeat for the rest of the layers.
b) Use the calculator to determine the thickness in centimeters for each layer. This is the
"scale depth” of each color you will draw in your jar.
i. Multiply the depth of the jar, 16.5 cm, by the percent you calculated for the crust.
ii. Write your answer in the Centimeters column.
iii. Repeat for the rest of the layers.
3: Color in the layers to create your drawing of a core sample.
a) Find the depth in centimeters for the inner core on your table.
b) Use the ruler to measure how thick the "scale depth" should be in the jar.
c) Locate the correct color of pencil for this layer in the data to
