37. most of the water on earth is located in the oceans and has a salinity of about 3.5%. which statement best explains why rain is fresh water and has a very low salinity? a. when water precipitates from oceans, most of the salt remains in the oceans. b. when water evaporates from oceans, most of the salt remains in the oceans. c. when water precipitates from clouds, most of the salt remains in the clouds. d. when water evaporates from clouds, most of the salt remains in the clouds.

When water evaporates to form clouds, it does not take minerals and salts from the ocean with it for they're too heavy to be carried with water vapour. Which explains why it's not salty.

B. When water evaporates from oceans, most of the salt remains in the oceans.

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.
