What is subsidence?

Subsidence is when a portion of the earth's crust is moved relatively lower. This commonly happens in tectonically active areas, such as plate boundaries. Subsidence can end up moving the crust below sea level, which can lead to the deposition of sediments and the formation of sedimentary rocks.
