8. Which statement correctly describes one way ocean currents affect a region? Deep ocean currents push into estuaries, creating sand deposits that form barrier
islands.
Cold ocean currents along the equator increase evaporation rates, creating circular
winds that produce tropical storms.
Warm ocean currents keep coastal air temperatures warm, creating moderate
climate conditions in coastal regions.
D. Deep ocean currents move water from polar seas toward the equator, creating drafts
of cold air that blow over polar regions.

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.
