The terrain is mostly mountainous and flat, with fast flowing rivers and few forests but with many trees. The climate is highland continental: hot summers and cold winters. The land rises to 4,090 m above sea-level at Mount Aragats.

Armenia is located in the southern Caucasus, the region southwest of Russia between the Black Sea and the Caspian Sea. [1] Modern Armenia occupies part of historical Armenia, whose ancient centers were in the valley of the Araks River and the region around Lake Van in Turkey. [1] Armenia is bordered on the north by Georgia, on the east by Azerbaijan, on the southeast by Artsakh, on the south by Iran, and on the west by Turkey. [1]

Topography of Armenia

Twenty-five million years ago, a geological upheaval pushed up the Earth's crust to form the Armenian Plateau, creating the complex topography of modern Armenia. [1] The Lesser Caucasus range extends through northern Armenia, runs southeast between Lake Sevan and Azerbaijan, then passes roughly along the Armenian-Azerbaijani border to Iran. [1] Thus situated, the mountains make travel from north to south difficult. [1] Geological turmoil continues in the form of devastating earthquakes, which have plagued Armenia. [1] In December 1988, the second largest city in the republic, Leninakan (now Gyumri), was heavily damaged by a massive quake that killed more than 25,000 people. [1]

About half of Armenia's area of approximately 29,743 km2 (11,483.8 sq mi) has an elevation of at least 2,000 m (6,562 ft), and only 3% of the country lies below 650 m (2,133 ft). [1] The lowest points are in the valleys of the Araks River and the Debed River in the far north, which have elevations of 380 and 430 m (1,247 and 1,411 ft), respectively. [1] Elevations in the Lesser Caucasus vary between 2,640 and 3,280 m (8,661 and 10,761 ft). [1] To the southwest of the range is the Armenian Plateau, which slopes southwestward toward the Araks River on the Turkish border. [1] The plateau is masked by intermediate mountain ranges and extinct volcanoes. [1] The largest of these, Mount Aragats, 4,090 meters (13,419 ft) high, is also the highest point in Armenia. [1] Most of the population lives in the western and northwestern parts of the country, where the two major cities, Yerevan and Gyumri, are located. [1]

The valleys of the Debed and Akstafa rivers form the chief routes into Armenia from the north as they pass through the mountains. [1] Lake Sevan, 72.5 km (45 mi) across at its widest point and 376 km (233.6 mi) long, is by far the largest lake. [1] It lies 1,900 m (6,234 ft) above sea level on the plateau and is 1,279.18 km2 (493.9 sq mi) large. [1] [2] Other main lakes are: Arpi, 7.5 km2 (2.9 sq mi), Sev, 2 km2 (0.8 sq mi), Akna 0.8 km2 (0.3 sq mi). [2]

Terrain is most rugged in the extreme southeast, which is drained by the Bargushat River, and most moderate in the Araks River valley to the extreme southwest. [1] Most of Armenia is drained by the Araks or its tributary, the Hrazdan, which flows from Lake Sevan. [1] The Araks forms most of Armenia's border with Turkey and Iran, [1] while the Zangezur Mountains form the border between Armenia's southern province of Syunik and Azerbaijan's adjacent Nakhchivan Autonomous Republic.

Climate

Temperatures in Armenia generally depend upon elevation. [1] Mountain formations block the moderating climatic influences of the Mediterranean Sea and the Black Sea, creating wide seasonal variations with cold snowy winters, and warm to hot summers. [1] On the Armenian Plateau, the mean midwinter temperature is 0 °C (32 °F) to −15 °C (5 °F), and the mean midsummer temperature is 15 °C (59 °F) to 30 °C (86 °F). [1] Average precipitation ranges from 250 millimeters (9.8 in) per year in the lower Araks River valley to 800 millimeters (31.5 in) at the highest altitudes. [1] Despite the harshness of winter in most parts (with frosts reaching −40 °C (−40 °F) and lower in Shirak region[ citation needed ]), the fertility of the plateau's volcanic soil made Armenia one of the world's earliest sites of agricultural activity.

Total renewable water resources:

7.77 m³ (2011) Armenia is considered to be a big water “supplier” in the Caspian basin; as a result, the country lacks water, especially in summer when the rate of evaporation exceeds the amount of precipitation. That is the main reason why since ancient times inhabitants have built water reservoirs and irrigation canals in the area. Lake Sevan contains the largest amount of water in the country.

Freshwater withdrawal (domestic/industrial/agricultural):
total: 2.86 km³/yr (40%/6%/54%)
per capita: 929.7 m³/yr (2010)

Geography of Azerbaijan Overview of the geography of Azerbaijan

Azerbaijan is a country in the Caucasus region, situated at the juncture of Europe and Western Asia. Three physical features dominate Azerbaijan: the Caspian Sea, whose shoreline forms a natural boundary to the east; the Greater Caucasus mountain range to the north; and the extensive flatlands at the country's center. About the size of Portugal or the US state of Maine, Azerbaijan has a total land area of approximately 86,600 square kilometers, less than 1% of the land area of the former Soviet Union. Of the three Transcaucasian states, Azerbaijan has the greatest land area. Special administrative subdivisions are the Nakhchivan Autonomous Republic, which is separated from the rest of Azerbaijan by a strip of Armenian territory, and the Nagorno-Karabakh Autonomous Region, entirely within Azerbaijan. The status of Nagorno-Karabakh is disputed by Armenia.

Geography of Iran

Geographically, Iran is located in West Asia and borders the Caspian Sea, Persian Gulf, and Gulf of Oman. Its mountains have helped to shape both the political and the economic history of the country for several centuries. The mountains enclose several broad basins, on which major agricultural and urban settlements are located. Until the 20th century, when major highways and railroads were constructed through the mountains to connect the population centers, these basins tended to be relatively isolated from one another.

Hrazdan (river)

The Hrazdan is a major river and the second largest in Armenia. It originates at the northwest extremity of Lake Sevan and flows south through the Kotayk Province and Armenia's capital, Yerevan; the lake in turn is fed by several streams. In the Ararat plain it joins the Aras River along the border with Turkey. A series of hydro-electric plants have been constructed on the river. Its waters are in demand to irrigate crops.

The river then enters the territory of Azerbaijan flowing for 43 km (27 mi) through the rayons (districts) of Qubadli and Zangilan. The lower section of the Hakari, from its confluence with the Vorotan until its confluence with the Aras river, is sometimes considered to be part of the Vorotan.
