Birbir River
The Birbir River of southwestern Ethiopia is a tributary of the Baro River, which it creates when it joins the Gebba at latitude and longitude . It is politically important because its course defines part of the boundary between the Mirab Welega and Illubabor Zones of the Oromia Region.
Fenristunga
Fenristunga () is a sloping field of ice within the rock walls of hairpin-shaped Fenriskjeften Mountain, in the Drygalski Mountains of Queen Maud Land, Antarctica. It was mapped from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60) and named Fenristunga (Fenrir's tongue) in association with Fenriskjeften Mountain.
Bird migration
Within a species not all populations may be migratory; this is known as "partial migration". Partial migration is very common in the southern continents; in Australia, 44% of non-passerine birds and 32% of passerine species are partially migratory. In some species, the population at higher latitudes tends to be migratory and will often winter at lower latitude. The migrating birds bypass the latitudes where other populations may be sedentary, where suitable wintering habitats may already be occupied. This is an example of leap-frog migration. Many fully migratory species show leap-frog migration (birds that nest at higher latitudes spend the winter at lower latitudes), and many show the alternative, chain migration, where populations 'slide' more evenly north and south without reversing order.
Glacier
On Earth, 99% of glacial ice is contained within vast ice sheets in the polar regions, but glaciers may be found in mountain ranges on every continent except Australia, and on a few high-latitude oceanic islands. Between 35°N and 35°S, glaciers occur only in the Himalayas, Andes, Rocky Mountains, a few high mountains in East Africa, Mexico, New Guinea and on Zard Kuh in Iran. Glaciers cover about 10 percent of Earth's land surface. Continental glaciers cover nearly 13,000,000 km2 (5×10^6 sq mi) or about 98 percent of Antarctica's 13,200,000 km2 (5.1×10^6 sq mi), with an average thickness of 2,100 m (7,000 ft). Greenland and Patagonia also have huge expanses of continental glaciers.
Samara Valles
Samara Valles is a valley bordering the Memnonia quadrangle and the Margaritifer Sinus quadrangle on Mars, located at approximately 25.1° south latitude and 19.1° west longitude. It is 615 km long and was named after the ancient name for modern Somme River, France.
Estonia
Estonia's land border with Latvia runs 267 kilometers; the Russian border runs 290 kilometers. From 1920 to 1945, Estonia's border with Russia, set by the 1920 Tartu Peace Treaty, extended beyond the Narva River in the northeast and beyond the town of Pechory (Petseri) in the southeast. This territory, amounting to some 2,300 square kilometres (888 sq mi), was incorporated into Russia by Stalin at the end of World War II. For this reason the borders between Estonia and Russia are still not defined.
Atlantis Chaos
Atlantis Chaos is a region of chaos terrain in the Phaethontis quadrangle of Mars. It is located around 34.7° south latitude, and 177.6° west longitude. It is encompassed by the Atlantis basin. The region is across, and was named after an albedo feature at 30° S, 173° W.
Central America
Central America (Spanish: América Central, Centroamérica) is the southernmost, isthmian portion of the North American continent, which connects with the South American continent on the southeast. Central America is bordered by Mexico to the north, Colombia to the southeast, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. The combined population of Central America is between 41,739,000 (2009 estimate) and 42,688,190 (2012 estimate).
Antarctica
New claims on Antarctica have been suspended since 1959 although Norway in 2015 formally defined Queen Maud Land as including the unclaimed area between it and the South Pole. Antarctica's status is regulated by the 1959 Antarctic Treaty and other related agreements, collectively called the Antarctic Treaty System. Antarctica is defined as all land and ice shelves south of 60° S for the purposes of the Treaty System. The treaty was signed by twelve countries including the Soviet Union (and later Russia), the United Kingdom, Argentina, Chile, Australia, and the United States. It set aside Antarctica as a scientific preserve, established freedom of scientific investigation and environmental protection, and banned military activity on Antarctica. This was the first arms control agreement established during the Cold War.
Geological history of Earth
The Ordovician Period started at a major extinction event called the Cambrian-Ordovician extinction events some time about 485.4 ± 1.9 Ma. During the Ordovician the southern continents were collected into a single continent called Gondwana. Gondwana started the period in the equatorial latitudes and, as the period progressed, drifted toward the South Pole. Early in the Ordovician the continents Laurentia, Siberia and Baltica were still independent continents (since the break-up of the supercontinent Pannotia earlier), but Baltica began to move toward Laurentia later in the period, causing the Iapetus Ocean to shrink between them. Also, Avalonia broke free from Gondwana and began to head north toward Laurentia. The Rheic Ocean was formed as a result of this. By the end of the period, Gondwana had neared or approached the pole and was largely glaciated.
East Africa
East Africa or Eastern Africa is the easterly region of the African continent, variably defined by geography or geopolitics. In the United Nations Statistics Division scheme of geographic regions, 20 territories constitute Eastern Africa:
Esperance Land District
Esperance Land District is a land district (cadastral division) of Western Australia, located within the Eucla Land Division on the state's south coast. It spans roughly 33°15'S - 34°00'S in latitude and 121°00'E - 122°20'E in longitude.
Cartavio, Peru
Cartavio belongs to the district of Santiago de Cao, Ascope Province, in the department of La Libertad in Peru. Its coastal location is north of Lima, at a latitude of 7°53'S and longitude of 79°13W and an altitude of 16m above sea level.
North Pole
The North Pole is the northernmost point on the Earth, lying diametrically opposite the South Pole. It defines geodetic latitude 90 ° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere.
Wells Land District
Wells Land District is a land district (cadastral division) of Western Australia, located within the Eastern Land Division of the state. It spans roughly 24°00'S - 26°20'S in latitude and 121°40'E - 123°20'E in longitude. Its name honours Lawrence Allen Wells, an explorer of the area in 1896–1897.
Bach quadrangle
The Bach quadrangle encompasses the south polar part of Mercury poleward of latitude 65° S. It is named for Baroque composer Johann Sebastian Bach (1685-1750).
Mount Chilalo
Mount Chilalo is an isolated, extinct silicic volcanic mountain in southeastern Ethiopia. The highest point in the Arsi Zone of the Oromia Region, and located on the border between the Hitosa and Tiyo woreda, this mountain has a latitude and longitude of with an elevation of above sea level.
Guinea-Bissau
Guinea-Bissau is bordered by Senegal to the north and Guinea to the south and east, with the Atlantic Ocean to its west. It lies mostly between latitudes 11° and 13°N (a small area is south of 11°), and longitudes 13° and 17°W.
Ayrılıkçeşmesi, Kadıköy
Ayrılıkçeşmesi is a quarter in Kadıköy district of Istanbul, Turkey. Due to its settlement type, its borders are not well defined, however the locality lies mostly within the neighborhood of Rasimpaşa.
30th parallel north
It is the approximate southern border of the horse latitudes in the Northern Hemisphere, meaning that much of the land area touching the 30th parallel is arid or semi-arid. If there is a source of wind from a body of water the area would more likely be subtropical.
