Final answer:
The text describes how wind currents are generated due to unequal heating of the Earth's surface, which leads to differences in air pressure. These variations mainly occur due to unequal heating between the equator and poles, and unequal heating of land and oceans.
Step-by-step explanation:
The passage you provided explains the relationship between air pressure, wind currents, unequal heating of the earth, and geographical coordinates. In simpler terms, the greater the difference in air pressure, the quicker air moves, creating wind currents. This air pressure difference is generated due to the earth's uneven heating by the sun. This phenomenon primarily happens in two scenarios: 1) Unequal heating between the equator and the poles of the earth, where the equator receives direct sunlight making it hotter than the poles. 2) The different heating properties of land and water bodies causing a temperature difference which results in air pressure variance and wind currents.
