3. Material X Supreme scratches calcite and apatite and is scratched by quartz and diamond ~ 6 Johnny rubbed a crystal of yellow topaz against a plate which left a white mark behind. Johnny told Sally to write down that the colour of the topaz must be white. 21 10 Do you agree? Why/Why not? The colour of the topaz is yellow. Johnny should have said the streak of the topaz is white. List three properties that all rocks must have: 1. Naturally occurring 22 11 2. Solid 3. One or more minerals joined physically Fill in the appropriate word in each of the 11, 12, 23 13, 16 What can affect the size of the crystals found in a rock? Where do you think the largest crystals form? 24 The rate of cooling affects crystal size. The largest crystals are formed deeper underground as they are closer to the hot mantle which causes them to cool down slowly. Draw and name two crystal shapes. Cubic Rhombohedral 25 15 Triclinic The pictures on the left represent the four stages of forming sedimentary rocks. 26 16 (note: nature doesn't use trucks!)
