Köppen climate classificationThe Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, German climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification.
CenoteA cenote (pronsᵻˈnoʊti or sɛˈnoʊteɪ; seˈnote) is a natural pit, or sinkhole, resulting from the collapse of limestone bedrock that exposes groundwater. The term originated on the Yucatán Peninsula of Mexico, where cenotes were commonly used for water supplies by the ancient Maya, and occasionally for sacrificial offerings. The term derives from a word used by the lowland Yucatec Maya—tsʼonoʼot—to refer to any location with accessible groundwater.
MuyilMuyil (also known as Chunyaxché) was one of the earliest and longest inhabited ancient Maya sites on the eastern coast of the Yucatan Peninsula. It is located approximately south of the coastal site of Tulum, in the Municipality of Felipe Carrillo Puerto in the state of Quintana Roo, Mexico. Artifacts found here date back from as early as 350 BC. to as late as 1200-1500 AD. The ruins of Muyil are an example of Peten architecture, like those found in southern Mayan sites with their steep walled pyramids such as Tikal in Guatemala.

JadeJade is a mineral used as jewellery or for ornaments. It is typically green, although may be yellow or white. Jade can refer to either of two different silicate minerals: nephrite (a silicate of calcium and magnesium in the amphibole group of minerals), or jadeite (a silicate of sodium and aluminium in the pyroxene group of minerals). Jade is well known for its ornamental use in East Asian, South Asian, and Southeast Asian art. It is commonly used in Latin America, such as Mexico and Guatemala.
