San Andreas Lake (from which the fault takes its name) is a ``sag pond'' that naturally formed in the valley of the San Andreas fault. Strike slip faults are good places for lakes; the fault both creates a low spot to collect the water, and grinds up the rock underneath making an impermeable layer to hold the water in.
In addition to providing us with shape and support for our skeleton, minerals are the âspark of life.â Minerals are essential in the diet and each plays unique and often multi-factorial roles as they act at all levels of the body â cells, tissues, organs, and the whole organism.
Iron is a mineral needed by our bodies. Iron is a part of all cells and does many things in our bodies. For example, iron (as part of the protein hemoglobin) carries oxygen from our lungs throughout our bodies. Having too little hemoglobin is called anemia. Iron also helps our muscles store and use oxygen. Iron is a part of many enzymes and is used in many cell functions. Enzymes help our bodies digest foods and also help with many other important reactions that occur within our bodies.
