pg.135 #1-10 questions in upco's phsical setting earth science book. help please i cant study without the answers and i have a HUGE test tommorow
1.which is the best example of physical weathering?
(1)the cracking of rock caused by the freezing and thawing of water
(2)the transportation of sediment in a stream
(3)the reaction of limestone with acid rainwater
(4)the formation of a sandbar along the side of a stream
2.two differnt kinds of minerals. A and B, were placed in the same container and shaken for 15 minuted. the diagram below represent the size ad shape of the various peices of mineral before and after shaing. what caused the resuting differences in shape and sizee of the minerals?
(chart not included)
(1)mineral B was shaken harder.
(2)Mineral B had a glossy luster.
(3)mineral A was more resistent to abrasion.
(4)mineral A consisted of smaller peices before shaking began.
(theres a chart for questions 3-7 not included in this)
3.which rock was found to have been exposed to weathering for the least number of years?
(1)granite (2)schist (3)marble (4)sandstone
4.in this study,which rock was the most resistant to weathering?
(1)marble (2)schist (3)granite (4)sandstone
5.what total percentage of the schist should have weathered away by the year 2020?
(1)1.0% (2)2.0% (3)0.5% (4)1.5%
6.point A on the diagram represents the time at which
(1)industrial polliitants changed the weathering rates
(2)the marble and schist weathered away at the same rate
(3)climatic conditions changed the weatherubg rates
(4)equal percentaged of the marble and schist had weathered away
7.studies have shown that pollutants added to the atmosphere in recent years are accumulating to cause an increase in the rate of weathering of marble.this factor should cause the line in the graph for marble in the future to
(1)decrease in slope(curve downward) (2)increase in slope(curve upward) (3)remain at the same slope
8.which property of water makes frost action a common and efective form of weathering?
(1)water dissolves many earth materials.
(2)water expands when t freezes.
(3)water cools the surrondings when it evaporates.
(4)water loses 80 calories of heat per gram when it freezes.
9.chemical weathering occurs most rapidly in climates which are
(1)moist and warm (2)moist and cold (3)dry and cold (4)dry and warm
10.two tombstibes, A and B, have each been standing in a cemetery for 100 years. the same style and size of lettering i clear on A but not on B. which is the most probable reason for the difference?
(1)B was more protected from the atmosphere than A.
(2)A's minerals are more resistant to weathereing than those of B.
(3)A is more porous than B.
(4)B is smaller than A.
