Question

Quizplus · Accepted Answer

This is true. Throughout Earth's history, sea level has fluctuated due to natural factors such as changes in climate and tectonic activity. During the last ice age, for example, sea level was much lower than it is today due to large amounts of water being locked up in ice sheets. However, there have also been periods in Earth's history when sea level was higher than it is today, such as during the Pliocene epoch approximately 3 million years ago.
