Tide
Tides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon, Sun, and rotation of the Earth.
The times and amplitude of tides at a locale are influenced by the alignment of the Sun and Moon, by the pattern of tides in the deep ocean, by the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see Timing). Some shorelines experience a semi-diurnal tide - two nearly equal high and low tides each day. Other locations experience a diurnal tide - only one high and low tide each day. A "mixed tide"; two uneven tides a day, or one high and one low, is also possible.
Tides vary on timescales ranging from hours to years due to a number of factors. To make accurate records, tide gauges at fixed stations measure the water level over time. Gauges ignore variations caused by waves with periods shorter than minutes. These data are compared to the reference (or datum) level usually called mean sea level.

Geography of Kyrgyzstan
Kyrgyzstan is a landlocked nation in Central Asia, west of the People's Republic of China. Less than a seventh the size of Mongolia, at 199,951 square kilometers, Kyrgyzstan is one of the smaller Central Asian states. The national territory extends about 900 kilometers from east to west and 410 kilometers from north to south.
Kyrgyzstan is bordered on the east and southeast by China, on the north by Kazakhstan, on the west by Uzbekistan and on the south by Tajikistan. The borders with Uzbekistan and Tajikistan in the Ferghana valley are rather difficult. One consequence of the Stalinist division of Central Asia into five republics is that many ethnic Kyrgyz do not live in Kyrgyzstan. Three enclaves, legally part of the territory of Kyrgyzstan but geographically removed by several kilometers, have been established, two in Uzbekistan and one in Tajikistan.
The terrain of Kyrgyzstan is dominated by the Tian Shan and Pamir mountain systems, which together occupy about 65% of the national territory. The Alay range portion of the Tian Shan system dominates the southwestern crescent of the country, and, to the east, the main Tian Shan range runs along the boundary between southern Kyrgyzstan and China before extending farther east into China's Xinjiang Uygur Autonomous Region. Kyrgyzstan's average elevation is 2,750 meters, ranging from 7,439 meters at Peak Jengish Chokusu to 394 meters in the Fergana Valley near Osh. Almost 90% of the country lies more than 1,500 meters above sea level.
