what is the present height of mount everest
Mount Everest On 9 October 2005, after several months of measurement and calculation, the Chinese Academy of Sciences and State Bureau of Surveying and Mapping officially announced the height of Everest as 8,844.43 m (29,017.16 ft) with accuracy of ±0.21 m (8.3 in). They claimed it was the most accurate and precise measurement to date.[36] This height is based on the highest point of rock and not the snow and ice covering it. The Chinese team also measured a snow-ice depth of 3.5 m (11 ft),[32] which is in agreement with a net elevation of 8,848 m (29,029 ft). The snow and ice thickness varies over time, making a definitive height of the snow cap impossible to determine.
Mount Everest The routes usually share one spot in common, the summit itself. The summit of Everest has been described as "the size of a dining room table".[269] The summit is capped with snow over ice over rock, and the layer of snow varies from year to year.[270] The rock summit is made of Ordovician limestone and is a low-grade metamorphic rock according to Montana State University.[271] (see survey section for more on its height and about the Everest rock summit)
