[ W ] C Causes of sea level rise

CCMcAXZ A O[h XZB The main cause of rising sea levels and expansion of the thermal waters, followed by melting of glaciers, which give the floor is melting ice in Greenland. PMcZAClAvUlAIfKvB Not rise by thermal expansion and melting just thinking on the decline or rise in sea level, considered separately once a couple of factors need to be a comprehensive summary of them.

• kCCCXZ : CXAXRnWZxCB Sea ice melting and sea Antarctic and Ocean Arctic: a lot of sea ice, can lower the concentration of salt from sea water by a freshwater inflow of melting glaciers and the inflow from rivers and coastal land. oACXZxACZxB Since the salt coagulation and precipitation, and salinity of sea ice is very thin, less than the concentration in seawater. AxCXB Therefore, sea ice is the density difference increases. Zx=xEAkCZiCZxAZiiZCB The rise of salinity difference being that depends on the density difference, especially in the Arctic Ocean to the lower salinity of the seawater itself forward as the melting, sea levels rise as per the amount of melting to go on record a lower melting .
• kXRZ : XRXRACo_X9xCAZZxCB Melting glaciers in Antarctica and the Arctic: the case of an iceberg of glacial origin, the volume of the glaciers at the sea from landREoTA volume increased 9 percent less than sea level, after only a few minutes to melt the sea level difference of more salt increase the volume.
• k AxnARXEcXEivyZ : ZCoACB Antarctica and the Arctic, high-latitude regions, permafrost melting snow remaining glaciers in the alpine:REoTA minutes in sea water and the melting, the increase in volume of the sea.
• C : XoACB Seawater inflow to the other: If the lake bottom of glacial runoff on the land, increase the volume of water volume only. AXyAZCC}lB Also, if there is sediment in the glacial water masses and the possibility that a sudden increase in volume flowing into the sea off with the melting.
• Mc : xMcA4xIB Expansion heat: the thermal expansion at different rates depending on temperature, 4 C volume off if the increase in acceleration fromRERE.
• : CACB Amount of evaporation: changes in the amount of evaporation from the sea, the sea change the volume. I~WB Are related to the amount of precipitation and indirectly.
• n` : ACN~ARyACn`CB Changes in the landscape: even if the volume does not change, uplift and subsidence of the seabed, and deposition of sediment derived from land, by sea level rise, changes in the terrain that borders the sea.
