Answer:
1. The layers are squeezed together and any water mixed in with the sediments is forced out. This process is called compaction. At the same time the particles of sediment begin to stick to each other - they are cemented together by clay, or by minerals like silica or calcite.
2.A mixtureis made up of two or more different substances. A mixture can contain solids, liquids and/or gases. The components in a mixture are not chemically joined; they are just mixed. That means we do not need to use chemical reactions to separate them.
3.When you add soap to the mixture, the hydrophobic end of the soap molecule breaks up the nonpolar oil molecules, and the hydrophilic end of the soap molecule links up with the polar water molecules. Now that the soap is connecting the fat and water, the non-polar fat molecules can be carried by the polar water molecules.
4.In order to ENGAGE students in this lesson, students make two observations and an inference about this image: Students will do their best, but the they often conflate observations and inferences. Answers like, "The chimp is looking for something to eat", are common.
