How does abrasion shape a shoreline?
rock fragments tumble in the water, wearing away material that is softer than they are.
wind picks up sand and blows it along the shoreline, changing the shape of the beach.
waves force air into cracks in the rock, breaking them apart.
currents flow parallel to the shore, moving large amounts of sediment.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
