To determine which location is most likely to have the greatest ocean salinity, we need to analyze the relationship between temperature and salinity. Higher temperatures generally lead to higher rates of evaporation, which in turn can increase the salinity of the ocean. Therefore, the location with the highest average yearly temperature is expected to have the greatest salinity.
The average yearly temperatures for the four locations are as follows:
- Location A: 31°C
- Location B: 23°C
- Location C: 18°C
- Location D: 48°C
We compare these temperatures to find the highest value:
- The temperature at Location A is 31°C.
- The temperature at Location B is 23°C.
- The temperature at Location C is 18°C.
- The temperature at Location D is 48°C.
Among these, the highest temperature is 48°C at Location D.
Thus, the location where the salinity of the ocean is most likely to be the greatest is:
Location D.
