Body waves can be divided into two types: primary waves and secondary waves. What is the difference between these two types of body waves?
What will be an ideal response?
Primary waves, as their name suggests, are the first to register on a seismograph. P-waves are fast, longitudinal waves that move out in all directions from their source. Because both solids and liquids respond to compressional/expansional movement, P-waves can travel through any type of material. Secondary waves are slower than P-waves; as such, they are the second to register on a seismograph. S-waves are transverse; they vibrate in an up-down, side-to-side fashion. Because liquids cannot support this type of movement, S-waves cannot travel through liquids.

Southwestern North America contains a large area called the Basin and Range province. What is the origin of this name?
A) Thrust faulting along the San Andreas fault produces linear ridges, the ranges, with intervening basinal valleys forming fault block mountains. B) Folds have formed by compressional stresses along the plate margin forming ridges (ranges) and valleys (the basins) of the basin and range province. C) The area is characterized by chains of volcanos forming ranges next to basins that form valleys. D) Ranges are uplifted horst blocks adjacent to basins formed as graben.
