It is normally caused by wind, but it can also be caused by aquatic vehicles such as boats and jet skis.

waves
Two examples of waves you can see are ocean waves at the beach and ripples on the surface of a pond or lake.
The highest lake waves cannot be as big as the highest ocean waves because lakes generally have smaller surface areas and lower wind fetches compared to oceans, which restricts the size of waves that can form. Additionally, ocean waves are influenced by longer and more powerful wind systems that can generate larger waves.
it causes current waves.
Winds and subsea movement of water.
because in the ocean is all around the earth and the moon has a little gravatational pull but its enough to pull the waves and make them bigger (if the moon is on your side of the earth) meanwhile the lake can only be on one side of the earth it does not have enough space to make big waves
Surface gravity waves not created by wind
Mostly its wind.
