<span>Thermohaline circulation is driven by differences by "Density." Thermohaline circulation is a single part of the large-scale ocean circulation. It is driven by global density differences that is being created by the freshwater fluxes and as well as the surface heat.</span>
The right answer for the question that is being asked and shown above is that: "D. It sets up two circulation cells where cool air aloft moves toward the equator and warm surface air moves toward the poles." uneven heating of the earth set up conditions for the prevailing winds on a nonrotating earth is that It sets up two circulation cells where cool air aloft moves toward the equator and warm surface air moves toward the poles.
Physical are like rivers, lakes , oceans and mountains
And human made /cultural features are like dams, buildings , canals stuff that aren't naturally here
The correct answer choice would be the third one: "Homer writes that Odysseus and his men 'were left to groan and wait for morning' (218)." In MLA, the period needs to be outside of the parentheses, not inside the parentheses or the quotation. So that leaves us between choices 2 and 3. Well, it isn't the second one because the way they cited it (Homer: 218) isn't correct, they should have written it as (Homer, 218). Therefore, the third one seems to be the most correct. Hope this helped some :)
