Pipi Natural Bridge
The Pipi Natural Bridge is geological formation near Ouadda in the Haute-Kotto prefecture of the Central African Republic in which the Pipi River, a tributary of the Kotto River, has carved out a gorge in the sandstone terrain forming a natural arch.http://www.hydrosciences.fr/sierem/produits/biblio/carte%20oro-hydrographque%20de%20la%20république%20centrafricaine.pdf p. 30 The sandstone arch is a single slab of sandstone, whose top is nearly above the water level. Although it is not known how it was formed, the surrounding terrain offers some clues. It is suspected that the top of the bridge was once part of the river bottom itself, as both the bridge and the current river bottom bear similar potholes. Upstream, rocky projections on the walls of the river gorge seem to suggest that a once-extant tunnel collapsed there. It has been suggested that the Pipi Natural Bridge is all that remains of that former tunnel. References Landforms of the Central African Republic Hau ...

Ouadda
Ouadda is a town located in the Central African Republic prefecture of Haute-Kotto. History On 10 December 2012, the rebels from Séléka seized Ouadda, as well as weapons left by fleeing soldiers.

Central African Republic
The Central African Republic (CAR; ; , RCA; , or , ) is a landlocked country in Central Africa. It is bordered by Chad to the north, Sudan to the northeast, South Sudan to the southeast, the DR Congo to the south, the Republic of the Congo to the southwest, and Cameroon to the west. The Central African Republic covers a land area of about . , it had an estimated population of around million. , the Central African Republic is the scene of a civil war, ongoing since 2012. Most of the Central African Republic consists of Sudano-Guinean savannas, but the country also includes a Sahelo- Sudanian zone in the north and an equatorial forest zone in the south. Two-thirds of the country is within the Ubangi River basin (which flows into the Congo), while the remaining third lies in the basin of the Chari, which flows into Lake Chad. What is today the Central African Republic has been inhabited for millennia; however, the country's current borders were established by Fran ...

Kotto River
The Kotto River (or Koto River) is a tributary of the Oubangui River in the Central African Republic. Its source is on the south side of the Bongo Massif, near Mount Toussoro on the border between the Central African Republic and Sudan. It flows generally north-east to south-west for past Bria, joining the Ubangi River east of Mobaye. The river separates the Tondou Massif from the Mongos chain to the north. There are several rapids along its course. The Kotto River gives its name to two of the Central African Republic's sixteen prefectures, Haute-Kotto and Basse-Kotto Basse-Kotto is one of the 16 and the least populated prefecture A prefecture (from the Latin ''Praefectura'') is an administrative jurisdiction traditionally governed by an appointed prefect.

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pothole (landform)
In Earth science, a pothole is a smooth, bowl-shaped or cylindrical hollow, generally deeper than wide, found carved into the rocky bed of a watercourse. Other names used for riverine potholes are pot, (stream) kettle, giant's kettle, evorsion, hollow, rock mill, churn hole, eddy mill, and kolk.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds., 2011. ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 800 pp. Although somewhat related to a pothole in origin, a plunge pool (or plunge basin or waterfall lake) is the deep depression in a stream bed at the base of a waterfall. It is created by the erosional forces of turbulence generated by water falling on rocks at a waterfall's base where the water impacts.Marshak, Stephen, 2009. ''Essentials of Geology,'' W. W. Norton & Company, 3rd ed. Potholes are also sometimes referred to as swirlholes. This word was created to avoid confusion with an English term for a vertical or steeply i ...

Landforms Of The Central African Republic
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
