Science Study Notes Inner Space Structure of the atom · An atom is the smallest part of an element that can be part of a chemical reaction - in other words‚ an atom is the smallest particle that can exist naturally · When two or more atoms join up they form a molecule. Atoms are generally found in the form of molecules. · An atom consists of a nucleus‚ which is made up of protons and neutrons. · Protons are positively charged particles. Neutrons have no charge. There is an outer layer made

An Introduction to Structural Geology Introduction Structural geology is the study of the features formed by geological processes. Features include faults‚ folds and dipping strata. Geologists can work out the order of events and see which events are related by taking fairly simple measurements and using simple methods. Measurements and Techniques The most obvious thing to do when trying to decipher the structural history of a formation is to describe it. One way of doing this is to measure the dip and strike
