What is the ultimate base level, and why is it called that? What will be an ideal response?
The ocean is called the "ultimate base level" because the ocean is here to stay geologically. This is not
to say that sea level itself is constant. It varies as a function of climatic fluctuations that affect global
ice volume. But the ocean is where river erosion ultimately ceases. Perplexingly, there are temporary
base levels that lie below sea level. The Dead Sea in the Middle East is a good example of this. It is a
body of water in an arid region that has no outlet to the ocean.
