Coal was created through the decomposition of ancient trees. Most of the coal was was formed 300 million years ago. At the time the earth was covered by swamps. When the ancient plants and trees died, their remains sank to the bottom of the those areas, making layers and layers of plant material and eventually forming a soggy, thick material called PEAT.

The Maya were certainly aware of, and were often admirers of, the Mesoamerican cultures which had gone before them, especially the Olmec and at Teotihuacan, and so they took inspiration from this Mesoamerican heritage when developing their own unique architecture.
Maya architecture is best characterized by the soaring pyramid temples and ornate palaces which were built in all Maya centres across Mesoamerica from El Tajin in the north to Copan in the south. The Maya civilization was formed of independent city-states and, consequently, there are regional variations in architecture but almost all buildings were constructed with a precise attention to position and layout and a general style prevails.
Multi-level elevated platforms, massive step-pyramids, corbelled roofing, monumental stairways, and exteriors decorated with sculpture and mouldings of Maya glyphs, geometric shapes, and iconography from religion such as serpent masks are all typical features of Maya architecture. Interestingly, unlike many other cultures, Maya architecture makes no particular distinction between religious and non-religious buildings.
