In general, we call the largest areas of land on earth the continents of the earth.
The Maya built great temples, palaces and pyramids in their city centers. These were often mighty stone structures, over which wooden buildings and thatched roofs were often built. The city center was the physical and spiritual heart of the city.
The Mayans also dug ditches for irrigation with stone and wood tools. Stone and wood used for building structures were cut with special hand tools made of volcanic glass or durable minerals. These tools were commonly made of chert, obsidian or jadeite.
