Foliation - ANSWERS* Planes of minerals formed in response to stress * A feature of many metamorphic rocks * crystals rearrange into layered planes depending on the type and orientation of the stress during metamorphism Foliation planes are recognized by: - ANSWERS* The preferred orientation of minerals * alternating bands of different minerals * the flattening and stretching of minerals * foliation forms by physical rotation of preexisting minerals Non-foliated rocks are named primarily a...

Compared to low-grade metamorphic rocks, high-grade rocks _____. (a.) always contain more quartz and feldspar (b.) are produced closer to the surface, high in the stratigraphic column (c.) are produced at greater temperatures and pressures (d.) are produced at cooler temperatures, but greater pressures - ANSWERS(c.) are produced at greater temperatures and pressures Two common metamorphic rocks that typically lack foliation are _____. (a.) slate and phyllite (b.) gneiss and migmatite (c....

When does metamorphism occur? What does metamorphism include? Meta. rocks compare to Ig. and Sed. rocks? Does Metamorphism have a solid/not solid state? What are these two types of changes? - ANSWERSOccurs at elevated temperature and pressure, typically at the base of mountains Includes Recrystallization, making new minerals from original minerals, and sometimes, changes in the texture of the Parent Rock (protolith). Metamorphic rocks are organized compared to Igneous and Sedim...

Metamorphism brings changes in mineral arrangement and the texture of rocks, but it never leads to new mineral assemblages. A. true B. false - ANSWERSB A buried body of shale is subjected to differential stress at temperatures greater than 200 C, causing clay minerals to grow in preferred orientation and producing slate.

contact metamorphism - ANSWERSoccurs when a magma chamber intrudes the surrounding rock; the heat from the magma metamorphoses the surrounding rock regional metamorphism - ANSWERSoccurs when pressure builds up in rock that is buried deep below other rock formations or when large pieces of the Earth's crust collide with each other (the increased pressure and temperature causes rock to become deformed and chemically changed) Metasomatism - ANSWERSVery hot, element-rich waters cause metamo...

rock cycle - ANSWERSa series of processes on the surface and inside Earth that slowly changes rocks from one kind to another migmatite - ANSWERSfoliated, ultra high-grade metamorphic rock with clear layers and large grains/bands gneiss - ANSWERSfoliated, high-grade metamorphic rock with visible mafic and felsic minerals schist - ANSWERSfoliated, high-grade metamorphic rock that has visible micas and has medium to large, flat, sheet-like grains in a preferred orientation contact metam...

foliation - ANSWERSSlaty cleavage, schistosity, and compositional banding are all examples of ___________. slaty - ANSWERS______ cleavage: parallel foliation of fine-grained platy minerals; produces the rocks slate and phyllite. schistosity - ANSWERS________ - the layering in a coarse grained, crystalline rock platy - ANSWERSMuscovite and Biotite are an example of _______ mineral grains. gneiss - ANSWERSMineral Banding (________) - The layering in a rock in which bands or lenses of G...

form at specific temperatures as a magma cools. At the higher temperatures associated with mafic and intermediate magmas, the general progression can be separated into two branches.

Reproductive: endometrial cycle and the occurrence of ovulation- the menstrual cycle consist of three phases: the follicular/proliferative phase (postmenstrual), followed by the luteal/secretory phase (premenstrual), and the ischemic/menstrual phase. *Ovarian hormones control the uterine (endometrial) events of the menstrual cycle. During the follicular/proliferative phase of the ovarian cycle estrogen produced by the follicle causes the endometrium to proliferate (proliferative phase) and indu...
