<u>Answer:</u>
<em>The exposure of sea bed or undersea surface is called sea-level regression.</em>
<u>Explanation:</u>
Sea-level regression occurs when sea level drops down due to several climatic changes. This triggers extinction of several species. There had been several mass extinctions in the past due to <em>sea-level regression.
</em>
<em>Chances of survival of shallow</em> water species become feeble when the sea level falls. In the case of mass extinctions regression can be seen as a symptom and not a cause.
Marine transgression is the opposite <em>phenomena of regression</em> where sea level rises and covers the land which was previously above the sea level.
