When scientists uncover a fossil, they record the precise location where the fossil was found. does this location provide useful evidence for conclusions about the fossil and evolutionary processes?
a. yes. patterns in the distributions of fossils and living species are useful evidence of evolution.
b. no. evidence for evolution comes only from body structures, not the environment of organisms.
c. yes. evolution occurs only in certain locations on earth, and not others. d. no. fossils and living species are distributed evenly across all of earth's land and water.

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
