What are some of the causes of eustatic change to sea level? Include local possibilities of sea level
change as well. What will be an ideal response?
ANS:Answer
should include:
? Global glaciation can make sea level lower. There is less water in the ocean because it
freezes into the glaciers.
? Warm periods can cause glaciers and ice caps to melt. This raises the level of the ocean.
Outgassing can also contribute to the heighten sea level.
? High rates of seafloor spreading can create large oceanic ridges. The expansion displaces
the water so the sea level gets higher. This also decreases the potential volume of the
ocean.
? Temperature can vary the amount of volume the water occupies.
? Uplift and atmospheric events that send water in motion can create local changes in sea
level. This includes wind and currents, seiches, storm surges and even El Niño and La
Niña events.
