We have all noticed that if we hike from a place with low elevation and go up at a place with high elevation, that the temperature is gradually dropping, thus giving us a clue that the lower places are warmer, while the higher places are cooler. The reason for this, even though both the places with low and high elevation are located in the troposphere, thus the same atmospheric layer, is that the density of it is not the same everywhere. The troposphere has the highest density at its lowest points, and as the height increase the density decreases. Since the higher parts are less dense, that means that there are less gases, thus there are less molecules that are further apart from each other. This results in lesser absorption of heat, so this parts are cooler, while the lower parts are warmer because the troposphere is denser, there's more molecules that are also closer to each other, thus they absorb more heat.
I think it would be c because an archipelago is a group of islands
Answer:
Naval bases , Refueling stations.
Explanation:
The Europeans have developed the pacific island of the Fiji, Nauru, Palau, Tonga and the Samoa, Vanuatu for the naval base and the refueling activities, similar to those of the Chinese there traces have been found in the 420 and the 200 B.C. The Melanesians, and Micronesians, Polynesians are some of the island groups that are explored by the Europeans and they are by the Portuguese explorers.
Explanation:
The greenhouse effect is related to the increase in the average surface temperature which is considered "global warming". Global warming is the result of an increase in gases like methane, carbon dioxide, and other factors that lead to a rise in the planet's temperature.
