Alvand Hamedan F
Alvand is a subrange of the Zagros Mountains in western Iran located south of the city of Hamadan in Hamadan Province. Its summit has an elevation of . The main body of the Alvand range extends for about 50 km from east to west, while their maximum north-south width is about 30 km. Formed as part of the Zagros orogeny in the late Jurassic and early Cretaceous, the mountains rise sharply from the surrounding plains and are scored by many deep valleys. The mountains are mostly granite and diorite, which are types of intrusive rock. The area was once covered by a light oak forest, but extensive deforestation in historical times has reduced this to only a small area, mostly in the valleys. Today, the higher altitudes have a sparse cover of grass, while grass cover grows more thickly around springs and streams. One important plant that commonly grows in the Alvand valleys is the ''gavar'' or goat's thorn, which produces the gum known as tragacanth which is used in medicin ...

Ultra Prominent Peak
An ultra-prominent peak, or Ultra for short, is a mountain summit with a topographic prominence of or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,524 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not Ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence. The term "Ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington (state), Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least of prominence. Distribution Currently, 1,518 Ultras have been identified above sea level: 639 in Asia, 356 in North America, 209 in South America, 120 in Europe (including 12 in the Caucasus), 84 in Africa, 69 in Oceania, and 41 in ...

Caspian Sea
The Caspian Sea is the world's largest inland body of water, often described as the world's largest lake or a full-fledged sea. An endorheic basin, it lies between Europe and Asia; east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau of Western Asia. It covers a surface area of (excluding the highly saline lagoon of Garabogazköl to its east) and a volume of . It has a salinity of approximately 1.2% (12 g/L), about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast. The sea stretches nearly from north to south, with an average width of . Its gross coverage is and the surface is about below sea level.

Talvar River
''Madan's Talwar'', later known as ''The Talvar'', was an early-20th-century Indian Nationalist periodical published from Berlin. Originally named after Madan Lal Dhingra, one of the heroes of the Indian independence movement who had been executed for the political assassination of William Hutt Curzon Wyllie, the publication was established in 1909 in Paris by Bhikaiji Cama. Editorial responsibilities lay with Virendranath Chattopadhyaya in Berlin. The weekly aimed to incite nationalist unrest and sought to sway the loyalty of the British Indian Army sepoys. Similar to the ''Bande Mataram'' that was published from Paris by the Paris Indian Society, it continued the message of ''The Indian Sociologist ''The Indian Sociologist'' was an Indian nationalist journal in the early 20th century.

Snowmelt
In hydrology, snowmelt is surface runoff produced from melting snow. It can also be used to describe the period or season during which such runoff is produced. Water produced by snowmelt is an important part of the annual water cycle in many parts of the world, in some cases contributing high fractions of the annual runoff in a watershed. Predicting snowmelt runoff from a drainage basin may be a part of designing water control projects. Rapid snowmelt can cause flooding. If the snowmelt is then frozen, very dangerous conditions and accidents can occur, introducing the need for salt to melt the ice. Energy fluxes related to snowmelt There are several energy fluxes involved in the melting of snow. These fluxes can act in opposing directions, that is either delivering heat to or removing heat from the snowpack. Ground heat flux is the energy delivered to the snowpack from the soil below by conduction. Radiation inputs to the snowpack include net shortwave (solar radiation including ...

Drainage Divide
A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be difficult to discern. A triple divide is a point, often a summit, where three drainage basins meet. A ''valley floor divide'' is a low drainage divide that runs across a valley, sometimes created by deposition or stream capture. Major divides separating rivers that drain to different seas or oceans are continental divides. The term ''height of land'' is used in Canada and the United States to refer to a drainage divide. It is frequently used in border descriptions, which are set according to the "doctrine of natural boundaries". In glaciated areas it often refers to a low point on a divide where it is ...

Turkish Language
Turkish ( , ), also referred to as Turkish of Turkey (''Türkiye Türkçesi''), is the most widely spoken of the Turkic languages, with around 80 to 90 million speakers. It is the national language of Turkey and Northern Cyprus. Significant smaller groups of Turkish speakers also exist in Iraq, Syria, Germany, Austria, Bulgaria, North Macedonia, Greece, the Caucasus, and other parts of Europe and Central Asia.
