Mare Imbrium (Latin for "Sea of Showers" or "Sea of Rains") is a vast lunar mare filling a basin on the Moon. One of the larger craters in the Solar System, Mare Imbrium formed when lava flooded the giant crater formed when a very large object hit the Moon long ago. Its age has been estimated using U-Pb dating methods to 3938 ± 4 Ma. The Moon's maria (plural of mare) have fewer features than other areas of the Moon because molten lava pooled in the craters and formed a relatively smooth surface. Mare Imbrium is not as flat as it was originally because later events have altered its surface.
With a diameter of 1146 km, Mare Imbrium is second only to Oceanus Procellarum in size among the maria, and it is the largest mare associated with an impact basin.
The Imbrium Basin is surrounded by three concentric rings of mountains, uplifted by the colossal impact event that excavated it. The outermost ring of mountains has a diameter of 1300 km and is divided into several different ranges; the Montes Carpatus to the south, the Montes Apenninus to the southeast, and the Montes Caucasus to the east. The ring mountains are not as well developed to the north and west, and it appears they were simply not raised as high in these regions by the Imbrium impact. The middle ring of mountains forms the Montes Alpes and the mountainous regions near the craters Archimedes and Plato. The innermost ring, with a diameter of 600 km, has been largely buried under the mare's basalt leaving only low hills protruding through the mare plains and mare ridges forming a roughly circular pattern.
Mare' (Arabic: مارع, also spelled Marea) is a town 25 kilometers north of Aleppo in northern Syria. It is the largest town and the administrative centre of the Mare' nahiyah in the Azaz District of the Aleppo Governorate. Nearby localities include Shaykh Issa and Tell Rifaat to the west, A'zaz to the northwest, Dabiq to the northeast, al-Bab to the southeast, and Maarat Umm Hawsh and Herbel to the south. According to the Syria Central Bureau of Statistics, it had a population of 16,904 in the 2004 census, out of a total population in the Mare' nahiyah of 39,306.
Mare' has been affected by the ongoing Syrian uprising against the government of Bashar al-Assad. The Ibn Walid brigade of the opposition Free Syrian Army was formed in the town in August 2012.
As of January 2015, Mare' is controlled by the Islamic Front.
The Mare' Operations Room is based around the town.
A mare is an adult female horse or other equine.
In most cases, a mare is a female horse over the age of three, and a filly is a female horse age three and younger. In Thoroughbred horse racing a mare is defined as a female horse more than four years old, but the word can also be used for other female equine animals, particularly mules and zebras, though a female donkey is usually called a "jenny." A broodmare is a mare used for breeding. A horse's female parent is known as its dam.
An uncastrated adult male horse is called a stallion and a castrated male is a gelding. Occasionally the term "horse" is used in a restrictive sense to designate only a male horse.
Mares carry their young (called foals) for approximately 11 months from conception to birth. (Average range 320–370 days.) Usually just one young is born; twins are rare. When a domesticated mare foals, she nurses the foal for at least four to six months before it is weaned, though mares in the wild may allow a foal to nurse for up to a year.
