Tang-e Gharu
Tang-e Gharu, also known as Tang-e Gharo (Pashto: تنگ غارو), is a gorge and a mountain pass in the Hindu Kush mountain range of Kabul Province, Afghanistan. The Kabul River passes through the gorge, flowing eastward. The Kabul–Jalalabad Road runs through the gorge, parallel to the river. Construction on the road began in the 1940s and was completed in the 1960s replacing the ancient Lataband Pass mountain pass. Both the pass and the road are considered to be of major strategic importance, as they provide a connection to Pakistan and Russia. Due to heavy usage during recent conflicts in Afghanistan and frequent traffic accidents, the pass and the surrounding areas have become heavily damaged and periodically closed off. Geology The cliffs of Tang-e Gharu gorge are a blue-grey limestone, which was formed some 250 million years ago. However, the gorge itself is only about 2 million years old and was formed as a combination of water erosion Erosion is the action of sur ...

Kabul–Jalalabad Road
The Kabul–Jalalabad Road, also known as National Highway 08 (NH08), is a highway running between the Afghan cities of Kabul (the national capital) and Jalalabad, the largest city in eastern Afghanistan and capital of Nangarhar Province. A portion of the road runs through the Tang-e Gharu gorge. The road is about long and travels upwards from an elevation of 575 m in Jalalabad to 1790 m in Kabul. Because of the many traffic accidents, the road between Jalalabad and Kabul is considered to be one of the most dangerous in the world. It consists of narrow roads with sharp turns past high cliffs and a valley of the Kabul River below, with which it runs parallel. It is a large part of the Afghan leg of the Grand Trunk Road. Parts of the road follow the British Army's disastrous 1842 retreat from Kabul. See also *Highway 1 (Afghanistan) ), is a two-lane road network circulating inside Afghanistan, connecting the following major cities (clockwise): Kabul, Maidan Shar, Ghazni, ...

Lataband Pass
The Lataband Pass or Kotal-e Latah Band, in pashto کوتل لته بند, (elevation: ) is a mountain pass connecting Kabul and Jalalabad on the way to Pakistan in the Karkacha hills between Seh Baba and Butkhak in the Hindukush Range. The name, Lataband, means 'Mountain of Rags' as there was an old belief that people who hung bits of clothing on the bushes along the way, had their wishes granted. Description The Lataband Pass is a difficult and dangerous pass which was on the only road suitable for carriages or motor vehicles between Kabul and Jalalabad until the longer, but less precipitous route via the Khord Kabul was used by the Moghuls in the 16th century. An integral part of the ancient Silk Road, it was still in use until 1960, when the route via Tang-e Gharu route was finally completed and paved. This new road reduced travel time between Kabul and the Pakistan border from two days to only a few hours. It was for many centuries an important link on the trade route between ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ...
