A, B, and C A transform boundary is characterized by A. plates sliding each other B. the movement of one plate over another C. the movement of plates away from each other D. earthquakes, but no plate movement Plate tectonic theory is considered a unifying theory because it A. explain evidence for a dynamic Earth from a variety of subdisciplines in geology B. a common belief of a broad spectrum of geologists from different disciplines C. current explanation for the such earth processes as volcanism and earthquakes D. is the only theory explaining earth dynamics that hasn't been disproves The three main rock types are distinguished on the basis of which of the following characteristics? A. composition B. texture C. size and shape of mineral or rock grains D. A and B E. A, B, and C Which of the following best describes sedimentary rocks? A. deposition of ash and larger particles produced by volcanism B. weathering, transport, and deposition of sediment from pre-existing rocks C. compaction and cementation of rock fragments, precipitates, and organic matter D. alteration of sediment by heat, pressure, and the chemical activity of water The evidence supporting the "Big Bang" theory includes A. an expanding universe B. a pervasive background radiation everywhere in the universe C. the existence of the Doppler effect D. A and B E. all of the above Mercury, Venus, Earth, and Mars are similar in that they have similar A. tectonism B. volcanism C. composition

Explanation / Answer

ANSWER:

9) Theories in geology are developed through a process known as scientific method

10) crust is formed along divergent boundaries and consumed along convergent boundaries

11) Their environments of formation ,their pobential change over time and their relation to internal and external earth processes (A,B and C)

12) A transform boundary is characterized by the movement of one plate over another

13) Plate tectonic theory is considered a unifying theory because it current explanation for the such earth processes as volcanism and earthquakes

14) The three main rock types are distinguished on the basis of composition, texture, size and shape of mineral or rock grains( A,B and C)

15) compaction and cementation of rock fragments, precipitates, and organic matter

16) The evidence supporting the big bang theory includes All of the above

17) Mercury venus earth and mars are similar in that they have similar volcanism
