1) The principle of original horizontality states that layers of sediment deposit along a horizontal plane due to the effects of characterized by fine-grained textures because their rapid cooling at or near the surface did not provide enough time for large crystals to grow. You will use the polar map given (Figure 2.8) to plot the changing locations of the magnetic pole over time. For a limited time, find answers and explanations to over 1.2 million textbook exercises for FREE! 90º N latitude is directly in the center of the map, and the lines of latitude, measured in 2-degree increments, spread out in circles from the center.
_____ rocks are formed when magma cools, which allows _____ crystals to form and become locked together to form the rock, plutonic (intrusive) and volcanic (extrusive), rocks formed when magma cools within the earth, well below the surface, rocks formed at or close to earth's surface, often a result of a volcanic eruption, provide information about volcanic eruptions, provide data regarding temperatures and magma types found below earth's surface, are used as construction materials, and produce commercial goods.

To view the polar map, imagine that you are above the North Pole looking down on it. as a separate file in whatever format is convenient (e.g., photo, scan, etc.). 3.1 Silicate Mineral Groups; Lab 3 Exercises; Summary; Lab 4: Igneous Rocks. 2.1 Bonding and Lattices; 2.2 Mineral Groups; 2.3 Mineral Properties; 2.4 Economic Minerals; Lab 2 Exercises; Summary; Lab 3: Silicate Minerals. Intrusive: Diorite. The cooling of magma deep in the Earth is typically much slower than the cooling process at the surface, so larger crystals can grow. rock gypsum, chert, oolitic limestone dolostone, soft, can be scratched easily with fingernail, made of microcrystalline quartz, therefore it is very smooth, has conchoidal fracture and is harder than glass. Are light colored, have low silica content, and contain quartz, feldspar, and orthoclase. Lab 1 Exercises; Summary; Lab 2: Mineral Properties and Non-Silicate Minerals. can be recognized by the presence of whole and/or broken fossils. 1. Introducing Textbook Solutions. This rock should be softer than glass (unlike chert). how do you identify an igneous rock (two properties of the rock)? made of the mineral dolomite (CaMg(CO3)2), which is similar to calcite, but will react to acid only when powdered. Extrusive: Andesite, Iron and magnesium rich dark colored has dark minerals, mixture of coarse and fine because of 2 stage cooling process; initial slow cooling, Largest crystal size, giant mineral crystals, course grains. make sure that your answers have the appropriate units!

Geology Lab 2 - Geology 102 with Hallett at University of Wisconsin - Oshkosh - StudyBlue Flashcards the size, shape, and arrangements of the particles that comprise a rock (useful for determining what category of igneous rock a specimen belongs to because plutonic rocks have different _____s than volcanic rocks), plutonic rock texture that has very coarse and large grain size, most crystals= >1 cm in diameter (some specimens have crystals several feet across), plutonic rock texture that has coarse and small grain size, crystal size= <1 cm in diameter, crystals are easy to see/large enough to see without magnification, rocks that contain some large grains (called phenocrysts) set into a matrix of much smaller grains, resemble a chocolate chip cookie, can form in both plutonic and volcanic settings, aphanitic, glassy, vesicular, and pyroclastic, volcanic texture that has small grain size (< 1 cm in diameter), can't see the individual crystals without magnification, volcanic texture that has no discernible grains even when using a hand lens, this texture can form when lava cools down extremely fast and forms volcanic glass, volcanic texture that is perforated with small openings (result of gas bubbles escaping from the lava as it finished cooling down), has a honeycombed appearance which causes the rock to feel unusually lightweight, volcanic texture that is comprised of solid, fragmentary material that was ejected from a volcano during an eruption; they lack the interlocked, crystalline appearance of most other igneous textures, the minerals that are present in an igneous rock (ex: granite has a ______ that includes quartz, orthoclase, and biotite), it is determined by identifying the major minerals present in the specimen (difficult because the minerals can be quite small) or by determining its color, a measurement of the percent of dark-colored minerals within the rock (possible because many minerals that are similar in color form under similar conditions), a composition of igneous rocks that has a high silica content, light in color (white, off-white, pink, and red), form at relatively low temperatures, associated with magma and lava present within continental crust, ex: quartz, orhtoclase, muscovite, and some types of plagioclase), a composition of igneous rocks that has a moderate silica content, grayish in color, roughly even mixture of only white and black minerals, form at high temperatures, ex: plagioclase, a composition of igneous rocks that has low silica content, typically dark in color (black, brown, and dark gray), form at higher temperatures, are associated with many volcanoes that are found on oceanic crust (such as the Hawaiian Islands), ex: hornblende and augite, a composition of igneous rocks that has low silica content, range from black to greenish-yellow color, form at very high temperatures, ex: olivine.
Some of our samples in lab may scratch glass due to quartz impurities, but you can identify this rock by the fact that it reacts to acid when you powder it.
