Long Term Sea Level Change
Looking at the average position of the sea level relative to the land. Change happens over the long term i.e. over thousands of years.
Change can result from one of three processes...
1. Eustatic Change
2. Isostatic Change
3. Tectonic Change.
This refers to a rise or fall in a level of the sea relative to the land. This is a global phenomena as its influence is world wide. It is a consequence of global temperature change.
For example, the Ice Age (periods of global cooling) created a fall in sea level because water was stored on the land as snow and ice. Here, the hydrological (water cycle) was interrupted by falling global temperatures/ percipitation does not return to the sea. Instead it stays in store on the land as snow and ice resulting in a fall…
