Have a look at this amazing footage showing part of a cliff collapsing and falling into the sea at Birling Gap in East Sussex.
The winter's extreme weather has led to about seven years' worth of erosion at the cliffs since January.
It's threatening cottages that are located by the coastline in south-east England.
