Consider the following statements regarding the factors that influence global or regional changes in sea level: I. Changes in the total volume of seawater due to the melting of land-based ice alter sea level globally. II. Tilting or warping of the Earth's crust can cause a relative rise or fall of sea level in specific regions. III. Mountain-building processes lead to global sea-level alterations primarily through thermal expansion. IV. Redistribution of mass on the Earth's surface, such as glacial loading or unloading, directly affects land elevation and relative sea level. Which of the statements given above are correct?
