A 1000 ml graduated cylinder contains an aqueous solution of soil. You notice three distinct layers after the solution was shaken and allowed to sit for 2 days; any organic material was removed. You observed layers within the column: sand, silt, and clay. Sand is on the bottom, silt in the middle, and clay on the top. After settling, the top layer goes from 920 ml down to 903 ml; the next layer from 903 down to 745, and the bottom layer from 745 to 0 ml.
a. Name the component of each layer.
b. What is the percentage of each layer?
c. What is this soil's textural callsification?
