1. The problem statement, all variables and given/known data
What are the causes of Global Sea Level Rise during the last century

A. Thermal Expansion of the Oceans
B. Melting of Glaciers
C. Post Glacial Rebound
D. A and B

ans D
It is possible to estimate Global Sea Level Rise using data from a hand-full of tide gauges.
A true
B False

ans B because geologically the height of the land can change.

A. Alpine glaciers and small ice caps melting (contain water to change sea level by 51 cm)
B. Greenland ice sheet (contains water to change sea level by 720 cm)
C. Changes to water stored on land have a major effect on global sea levels
D. A and B

ans D, I dont know if the source where I am getting this answer is right, but I am just wondering if you agree

During El Niño events:
A. Sea levels in Peru are higher than they are during non El Niño events
B. Sea levels in Peru are lower than they are during non El Niño events
C. Sea levels are higher globally
D. Sea levels are lower globally

ans B, sea levels are higher at peru during el nino event

Relative Sea Levels in the Gulf Coast of the United States are rising at rates much greater than the global overage due to:

A. Post Glacial Rebound
B. A Strong La Niña
C. Sediment Load on the continental shelf
D. Antarctic ice melting

D, I don't think that the rise of land masses influences the rise of sea levels.
2. Relevant equations

3. The attempt at a solution

Tthe question asks for the rise relative to the ground.
Why should melting ice in the Antarctic influence the US gulf coast in particular?
