Other airmass types include arctic, equatorial, and monsoon. Fronts are the boundaries between air masses of different temperature. Extratropical cyclones (low pressure areas) also form along these fronts and draw their energy from the temperature difference between air masses. On average, warm air masses tend to flow poleward, and cold air masses tend to flow equatorward, helping to cool the tropics and warm the polar regions.

Aztecs used relatively primitive tools for Aztec farming and agriculture. They did not have advanced tools for the time such as plows. The most important tool for Aztec farming and agriculture was the classic wooden digging stick. This stick was called Uictli in the Nahuatl language. There were multiple types of these digging sticks and other than farming, it was often also used for other purposes such as construction and repair work.
The advances demonstrated in Aztec technology are so remarkable that they are still looked upon adoringly to this day. Just a few of the Aztec accomplishments have been the development of mathematics, the canoe, the highly specialized Aztec calendar, and remarkably helpful forms of medicine.
