What is more salty the gulf of mexico or the gulf of california? Why?

You need to check this: Only one fresh water river flows into the GofCalifornia, but many flow into GofMexico. So...

To determine which is saltier between the Gulf of Mexico and the Gulf of California, we need to consider the factors that contribute to their salt content. One such factor is the presence of freshwater rivers.

The Gulf of California has only one major freshwater river flowing into it, which is the Colorado River. On the other hand, the Gulf of Mexico receives the discharge from numerous freshwater rivers, including the Mississippi, the Rio Grande, and the Mississippi-Atchafalaya river system.

The inflow of freshwater from these rivers reduces the overall salinity of the Gulf of Mexico. The Gulf of California, however, receives relatively less freshwater input, allowing the evaporation of seawater to concentrate the salt content. As a result, the Gulf of California tends to be saltier than the Gulf of Mexico.

To confirm the salinity levels, you can consult scientific resources, such as oceanographic studies or research papers, which provide data on the actual salinity measurements of these two bodies of water.
