Characteristics of the San Andreas Fault Zone. The surface expression of the San Andreas transform fault zone is a right-lateral strike-slip fault. The fault zone is approximately 1300 km long and is made up of three major segments, each with characteristic types, magnitudes and frequencies of earthquake activity.he San Andreas fault is one of only a few examples of a transform boundary between two tectonic plates that is exposed on a continent. Some other continental transforms are the Alpine fault in New Zealand and the Dead Sea Transform fault system in the Middle East.
Sulfur or sulphur (see spelling differences) is a chemical element with symbol S and atomic number 16. It is an abundant, multivalent non-metal. Under normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S 8.Elemental sulfur is a bright yellow crystalline solid at room temperature.lemental sulfur occurs naturally as the element (native sulfur), but most commonly occurs in combined forms as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and Egypt.
Sulfur in SF4 is in the formal +4 oxidation state. Of sulfur's total of six valence electrons, two form a lone pair. The structure of SF4 can therefore be anticipated using the principles of VSEPR theory: it is a see-saw shape, with S at the center. One of the three equatorial positions is occupied by a nonbonding lone pair of electrons.
