Question

question:
what change causes marine transgression and regression?

answer options:
select one of four
heat increasing and decreasing salinity increasing and decreasing
sea levels rising and falling tectonic movement in all directions

Explanation:

Marine transgression is when sea level rises, causing the shoreline to move inland, and regression is when sea level falls, moving the shoreline seaward. Heat and salinity changes don't directly cause these, and tectonic movement in all directions is not the primary cause. Sea level changes (rising and falling) are the main drivers.

Answer:

Sea levels rising and falling
