Final answer:
Flooding can be caused by tectonic hazards such as landslides, earthquakes, and volcanic eruptions.
Step-by-step explanation:
Flooding can be caused by several tectonic hazards, including landslides, earthquakes, and volcanic eruptions.
When slopes become saturated with water due to snowmelt or heavy rains, they can develop debris or mud flows. These flows of rock and mud can block bridges and tributaries, causing flooding along the path of the flow.
Earthquakes can also trigger landslides, which can in turn cause river flooding. Additionally, volcanic eruptions can produce loose ash deposits, heavy rain, and debris flows that can result in river flooding.
