Santos and Lüderitz are the same distance from the equator, and both cities
are near the ocean. The air temperature in Lüderitz is colder than the air
temperature in Santos. What causes the air temperature in these places to be
different? Explain what causes the difference as completely as you can.

The difference in altitude between these two regions.

Explanation:

As you can see in the question above, Lüderitz and Santos are two regions that are the same distance from the equator, which indicates that the two regions have the same latitude and are in tropical zones. In addition, the two regions are close to the ocean, but the air in Lüderitz is cooler.

This indicates that there is a difference in altitude in these regions and Lüderitz has a higher altitude than Santos, which is why Lüderitz's air is colder and Santos's is hotter.

Altitude is a geographic term that represents the distance of a region in relation to the level of the sea. The higher the altitude, the greater the distance.

The higher the altitude of a region, the colder its air will be. This is because in high altitude regions, air is thin and has a small capacity to retain heat.

a. the production of carbon dioxide through the process of photosynthesis

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
