Oceans, Rivers and Lakes

We are studying the differences and specific characteristics of these bodies of water.

  OCEANS

An ocean (from Ancient Greek Ὠκεανόςtransc. Okeanós, the sea of classical antiquity[1]) is a body of saline water that composes much of a planet's hydrosphere.[2] On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the PacificAtlanticIndianSouthern (Antarctic), and Arctic Oceans.
The bluish color of water is a composite of several contributing agents. Prominent contributors include dissolved organic matter and chlorophyll.[30]
Mariners and other seafarers have reported that the ocean often emits a visible glow which extends for miles at night. In 2005, scientists announced that for the first time, they had obtained photographic evidence of this glow.[31] It is most likely caused by bioluminescence.

RIVERS

river is a natural flowing watercourse, usually freshwater, flowing towards an oceansealake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features,[1] although in some countries or communities a stream is defined by its size.

LAKES

lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake.[1] Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions.[2]Lakes can be contrasted with rivers or streams, which are usually flowing. Most lakes are fed and drained by rivers and streams.
Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age

Our Visit to the Marigalante =)





Today we visited the "Marigalante" ship. It was an amazing experience.
We learned lots of things and had lots of fun.
Here´s some information about this ship:

Since 1995, the Marigalante has been one of the most popular party boats on Banderas Bay, and one of the most recognized symbols of Puerto Vallarta. Unlike any other vessel on Banderas Bay, this beautiful craft is an exact replica of the Santa María, one of the ships used by Christopher Columbus over 500 years ago to discover new lands.

The Marigalante was built in Alvarado Veracruz, Mexico by the Mar, Hombre y Paz Civil Association, (Sea, Man and Peace a non-profit organization,) to commemorate historical voyages, especially the 500th Anniversary of the Discovery of America. Over 30 types of tropical woods were used during construction, which began in 1980 and was completed in 1987.

On September 26 1987, the Marigalante took her maiden voyage from Alvarado Veracruz to Santoña in Cantabria Spain, the birthplace of Juan de la Cosa, the author of the very first Mapa Mundi. The owner of the Santa Maria, Cosa sailed with Columbus on his first three voyages to the New World, and was the master and cartographer of the Marigalante in 1493.

From Santoña, the Marigalante sailed to Seville and up the Guadalquivir to deliver 10,000 "Maravedies" gold coins corresponding to the payment promised by Christopher Columbus - and never paid - to the first man to shout "Land Ho!" This reward was due to Rodrigo de Triana, whose real name was Juan Rodriguez Bermejo.

The coins were collected from the 33 American countries and spanned various centuries. They were placed in a chest built with the same thirty types of wood as those used to built the Marigalante. The chest is exhibited in "La Antigua" chapel in the Cathedral of Seville.

The Marigalante then sailed the Nao route, from Acapulco to the Orient, visiting Japan for the commemoration of its 100 years of trade with Mexico. She also followed the Cocoa route to South America and sailed to Spain once again in 1992 for the 500th Anniversary of the discovery of America.

The Marigalante's voyage covered 87 ports and islands around the world, totaling 52,000 nautical miles or 96,304 kilometers - the equivalent of 2-1/3 trips around the world. Since then, the Marigalante has been sailing the length and breadth of the Bay of Banderas, sharing the magic, the joy and the culture of our beloved Mexico with all the tourists who visit Puerto Vallarta.
