A thermal overload is typically wired in parallel with the common terminal of a compressor.

Use the maps shown below to answer questions A thru D and label your answers as A through D in your typed response. The upper map shows sea-surface salinity and the lower map shows the oxygen isotope (del18O) composition of the surface ocean. Figure 1: Global map showing sea-surface salinity.   Figure 2: Global map showing the oxygen isotope (d18O) composition of the surface ocean.   A. (2 pts) The subtropics in both hemispheres are very arid regions with higher sea-surface salinities, why? B. (2 pts) Sea-surface salinities are relatively low at about 5ºN of the equator in both the Atlantic and Pacific Ocean basins, why? C. (2 pts) Comparison of the two maps clearly shows that surface-ocean del18O composition closely tracks sea-surface salinity, why? D. (2 pts) Look at the map showing surface-ocean del18O. Why does the surface-ocean del18O composition decrease with increasing latitude?
