Sedimentary rocks a. are formed by depositing loose materials in layers O b.are formed from a melt (molten rock lava or magma) care formed by depositing sediment (loose clasts or other materials) on Earth's surface, followed by compaction and cementation O d. are formed by changing existing rock by the application of heat and pressure QUESTION 2 The difference between sediment and sedimentary rocks is: O a none, there is no difference b. sediment is composed of loose clasts, sedimentary rocks contain cethented clasts O c sedlemnt forms from sedimentary rocks by weathering Od sediment is composed of cemented clasts, sedimentary rocks contain loose clasts QUESTION 3 How are clasts of sedimentary rock relate to the energy of the water transporting them? a. the smaller the clasts and the more well sorted the higher the energy of the water Ob the larger the clasts and the more well sorted the higher the energy of the water c. the larger the clasts the higher the energy of the water d. the smaller the clasts and the more angular, the higher the energy of the water.

QUESTION 4 Transportation is part of the process that forms clastic sedimentary rocks. During transportation clasts becomes a. all of similar size (well sorted) b. smaller, rounded and of similar size (well sorted) O smaller O d.less angular and more rounded QUESTIONS 2 types of clasts are shown in A and B. These clasts went through different lengths of transport (short transport closer to the clast source: long transport further away from the clast source) Complete the blanks in the following statement Clasts in A are to the clast source because they are than clasts in B A B O a closer, closer together b. closer larger further away, larger d. further away closer together e

QUESTION 6 2 types of clasts are shown in A and B. These clasts went through different lengths of transport (short transport closer to the clast source long transport further away from the clast source). Complete the blanks in the following statement Clast types similar to the clast shown in A are to the clast source because they are than clast types such as shown in B A B 6 a closer, more rounded D. further away, more rounded c. further away, more angular d.closer, more angular

QUESTION 7 2 types of clasts are shown in A and B. These clasts went through different lengths of transport (short transport closer to the clast source: long transport further away from the clast source). Complete the blanks in the following statement Clasts in A are to the clast source because they are compared to clasts in B А B a. closer, well sorted (all same size) b.further away well sorted (all same size) c closer poorly sorted (many sizes) d. further away, poorly sorted (many sizes)

QUESTION 8 2 types of clasts are shown in A and B These clasts went through different lengths of transport (short transport closer to the clast source long transport further away from the clast source) As a result of the transport, the composition of the clasts changed Complete the blanks in the following statement Clasts in A are to the clast source because they include compared to clasts in B A. В. Lithic clast Legend: Lithic clast = clast Quartz sand grain of rock from the Silt grain clast source Feldspar Clay flakes = clay minerals, very Clay flakes small in size a. further away, a mixture of stable and unstable minerals and rock fragments Ob.closer a mixture of stable and unstable minerals and rock fragments c further away only single stable mineral Od. closer only single stable mineral

QUESTION 9 Transportation is part of the process that forms clastic sedimentary rocks. If the transportation is very short, OR IS carried out by glaciers, the composition of the clasts includes: O a. a mixture of unstable and stable minerals and rock fragments Ob.clay minerals only Oc stable minerals only O d. quartz only QUESTION 10 Feldspar is a mineral that is unstable under chemical weathering at the Earth's surface. An arkose, a sandstone with abundant feldspar clasts Indicates: a. mature clastic rock b.ard (dry) conditions c. short transport of the clasts O d. both short transport and dry climate

QUESTION 11 Many beach sandstone contain clasts of: O a boitite and feldspar and quartz Ob.quartz only O c feldspar and quartz O d. quartz and micas QUESTION 12 Lepas the place wihere the clasts first weathered from the original source fècks. sedimentary rock O b. The place where the clasts spent the most time during their transport O c. The place where the clasts of this rock settled (deposited and accumulated) Od. The place where the clasts were moving the fastest during their transport.

QUESTION 13 Consider these clastic sedimentary rocks: 1. mudstone or shale (microscopic very small grain size) 2. conglomerate (grain size larger than 1/10 inch (2 mm), can be quite large) Which types of depositional environments can fit these rocks (1, 2:above), respectively? O a 1 - lagoon, 2-slow moving river within a delta Ob. 1 - slow moving river or river banks of meandering river, 2 - lagoon or a marsh O c 1 - beach area under waves, 2 - slow moving river Od. 1 - calm water such as deep ocean or lake, 2 - high energy river as found in mountains ho QUESTION 14 ♡ Below are listed the descriptions of the four main types of sedimentary rocks: 1. loose pleces of rocks and/or minerals, cemented together 2. cemented shells or skeletons of once living organisms 3. minerals that precipitated (crystallize) directly from water, then cemented 4. sedimentary rocks containing much organic matter (altered flesh of once living organisms) Sielect the types of sedimentary rocks that best fit these numbered descriptions (1, 2, 3, 4); O a. 1- chemical 2 - biochemical, 3 - clastic, 4 - organic 6.1 - clastic 2- biochemical, 3 - chemical, 4 - organic Oc 1 - biochemical, 2-clastic 3 - chemical, 4 - organic O d. 1. chemical, 2 - organic 3 - clastic 4 - biochemical
