Achanging climate has strong implications for biodiversity studies of fossit and polten distribution show that species are
very sensitive to climate changes. when the climate changes, species often die out in their present areas and colonize new
areas. therefore, as the climate changes in the future, there will be distuption of natural communities and extinction of
populations and species
which of these environmental changes would most affect the arctic polar bears survival?
drought
an ice age
deforestation
d)
global warming

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
