Question

Does the water level increase or decrease at the earth with the passage of time?

Answer 1

Rising temperature can cause polar and mountain top ice to melt, raising global sea levels. The biggest sea level rise comes from ice mounded up atop continents. Since this ice is not floating, it’s not currently displacing any sea water, so when it melts, it all ends up raising sea level. If all such ice on Earth today were to melt, sea levels would rise about 30 meters. Over the last 14,000 years, as ice sheets retreated at the end of the last ice age, sea levels have risen 190 meters, flooding the continental shelves. Sea level rises further as the oceans warm because water expands as it’s heated.
