Thermal Expansion of Water UCAR Center for Science Education

A greater volume of ocean water due to thermal expansion casuses a rise in sea level. Second rising temperatures are causing ice and snow on land to melt thereby increasing the amount of water in the oceans. (Only melting of ice and snow that are on land will increase sea level. The melting of floating ice will not affect sea level.)

Introduction to the Thermal Properties of WaterBright

Thermal Expansion of Water. Most solids and liquids expand with rising temperature. Water the most common and most important liquid on Earth has a limitation on this expansion. Ice water that is at a temperature of 0oC or 32oF will contract when it is heated. This contraction continues until after an increase beyond 4oC or 39.2oF.
