Question: What continent are the countries where Coiba Plates are located on? Passage 1:Waring's training began in 1939 in San Francisco and Oakland at the age of 17. He was exposed to numerous kinds of dancing, including ballet at the San Francisco Ballet School with Harold Christensen and his brother, the Graham technique with Gertrude Schurr, and the interpretive dance of Raoul Pause. Later, after serving in the Army in World War II, he studied in New York City at the School of American Ballet, and with Anna Halprin, Louis Horst, Antony Tudor, and Anatole Vilzak, and also took some classes with Merce Cunningham. Waring was very attracted to ballet and intrigued by its complex history and sensibility, and dance historian David Vaughan suggests that Waring's extensive knowledge of dance history played an important role in his work; Waring's dances became more balletic over time.
Passage 2:It ran from McDonough in the north through several communities in Henry County, GA such as Greenwood and Luella into northern Spalding County, GA passing through Experiment, GA and crossing the Central of Georgia Railroad in Griffin, GA. From there it ran south toward Williamson, GA in Pike County, crossing the old A&F line, and on into Concord, GA then on into Meriwether County, GA where it passed through Woodbury, GA. It then continued south toward and through Warm Springs, GA and then further south into Columbus, GA. Portions of this line still exist, mostly from McDonough to Greenwood (Liberty), and from the northern Spalding County line near the old Towaliga Station toward Experiment. This section is currently being refurbished by the Roosevelt Railroad. Then from Griffin south to Georgia State Route 362. Most all the other stretches have been pulled up.
Passage 3:The Coiba Plate is a small tectonic plate (a microplate) located off the coasts south of Panama and northwestern Colombia. It is named after Coiba, the largest island of Central America, just north of the plate offshore southern Panama. It is bounded on the west by the Cocos Plate, on the south by the Malpelo Plate, on the east by the North Andes Plate, and on the north by the Panama Plate. This microplate was previously assumed to be part of the Nazca Plate, forming the northeastern tongue of the Nazca Plate together with the Malpelo Plate. Bordering the Coiba Plate on the east are the north-south striking Bahia Solano Fault and east of that, the Serrania de Baudo, an isolated mountain chain in northwestern Choco, Colombia.
