Which data from ocean rocks showed seafloor spreading and convinced scientists the theory of plate tectonics was valid? a. density studies b. paleomagnetism c. ocean salinity studies d. seamount origins need ! will mark

I believe that paleomagnetism was a key to determining that the seafloors were spreading since the paleomagnetism changes at certain geological intervals so that stripes of new rock with the youngest paleomagnetism would be right at the mid-ocean trenches and successively would be older the further they are from the trench, ie on either side of it, symmetrically.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
