Question

Most sedimentary rocks are deposited mountainous regions. Indicate with a capital letter whether the following are rocks (R), minerals (M), or elements (E). Put the appropriate capital letter in the blanks, (a) Rhyolite; Garnet mica Schist; (c) Diopside; (d) Arsenic; (e) Europium; (f) Harzburgite; (g) Sodium; (h) Glaucophane: (i) Chromite; (j) Beryllium which of the following may influence the value of a rock or mineral or the hazard posed by it (circle best answer). crystal structure; (b) chemical composition; (c) hardness; (d) optical properties (such as luster and color); (c) (all of the above: a through d); (f) none of the above. for mineral or rock and 5 pts for human use of it) Name a mineral or rock. EXCLUDING any mineral or rock composed of a single element, that constitutes a resource exploited by humans and explain how this resource is used. Note that in years past students have repeatedly used minerals that are composed of a single element-such an answer will be worth ZERO points. Also, do NOT use coal because this is not technically a rock or mineral, cither. The same is true of petroleum (not a rock). Coal and petroleum as answers will also be worth ZERO points. (for each correct ranking) Rank the following three types of sedimentary rocks in terms or rate of sedimentation from highest (1) to lowest (3). by assigning numbers from 1 to 3 to the following (write number rank after the following rock types): sandstone chert limestone Which is likely to have been deposited furthest from a continent (circle best answer): (a) sandstone or (b) chert (for each rock name) Name one example each of three sedimentary rock types. This should be a common example, not an exception. Be sure to use a ROCK, not mineral name, otherwise you will not receive credit. clastic sedimentary rock biogenic sedimentary rock chemical sedimentary rock (for each correct ranking). Rank the following three types of sedimentary rocks in terms of their abundance from highest (I) to lowest (3) by assigning numbers from 1 to 3 to the following (write number rank after the following rock types). siliceous (biogenic) sedimentary rocks clastic sedimentary rocks carbonates (biogenic)

Explanation / Answer

7) false

reason : sedimentary rocks are mostly deposited in layers that also mostly underwater . The young layers a occupy top position and old layers occupy bottom position

8)rhyolite - rocks(R) -  volcanic rock of granitic composition

b) garnet - mica schist - rock(R)

C)diopside - mineral (M) -  it is a monoclinic pyroxene mineral with composition MgCaSi2O6

d)arsenic - element (E)

e)europium - element (E)

f)harzburgite - rock(R) -a plutonic rock of the peridotite group

g)sodium - element (E)

h)glaucophane - mineral(M)

i)chromite -mineral(M)  - It is an oxide mineral belonging to the spinel group

J)beryillium - element
