Final answer:
A seiche is a standing wave that occurs in an enclosed or partially enclosed body of water, such as a lake or a harbor. It is usually caused by the displacement of water due to external factors such as strong winds or atmospheric pressure changes.
Step-by-step explanation:
A seiche is a standing wave that occurs in an enclosed or partially enclosed body of water, such as a lake or a harbor. It is usually caused by the displacement of water due to external factors such as strong winds or atmospheric pressure changes.
Seiches can be created when the wind pushes water to one side of the body of water, causing the water to accumulate there. When the wind stops, the accumulated water then moves back to the other side, creating a back-and-forth oscillation.
For example, if the wind blows from the east, it can push the water to the western side of a lake. Once the wind stops, the water then moves back to the eastern side due to gravity, creating a seiche.
