Shown below are a stratigraphic section with the sequence of rock layers, and a geologic cross section across the dome. Using these two ﬁ gures and the strategies in Section 2.2, determine the order in which the layers were formed, and write your answers on the worksheet. Units A, B, and C have a Jurassic age, whereas units D and E are Triassic.

Answers to Chapter 3 Review Questions 1. In short, the magma from which igneous rocks form may be produced when any rock is melted. Sedimentary rocks are formed from the weathered products of preexisting rocks, whether igneous, metamorphic, or sedimentary. Finally, metamorphic rocks are created when any rock type undergoes metamorphism. 2.
Two primary types of sedimentary rocks: Chemical - precipitate from solution (e.g., limestone); most important constituents are calcite, dolomite, chalcedony (SiO 2), gypsum, and halite. Chemical sedimentary rocks can be further divided as to: inorganic (e.g., limestone, rock salt, dolomite) organic (e.g., limestone or coal).

It is held with both hands and the thumbs are used to handle the direction and action buttons. It has a six-axis sensing system, which allows the user to move the controller in six...
Chemical Sedimentary Rocks •Forms after the concentration of dissolved minerals reaches saturation and crystal grains settle out •Water evaporates and the minerals become more concentrated leading to thick layers on the bottom of a body of water. –Usually forms in areas that lack precipitation
