Eustatic change Flashcards
1
Q
Eustatic change happens due to
A
changes in the amount of ice, as a result of thermal expansion and tectonics
This change will be global

A
melting ice creating well-known waterways like the English Channel
Sea levels may also decrease when ice forms, locking water away in the ice sheets and glaciers
3
