Question

1. which of the following is not a generating force for a wave?

wind

ice breaking off from glaciers

landslides

earthquake

gravity

Explanation:

Wave - generating forces typically involve external disturbances or dynamic events. Wind creates wind - driven waves. Ice breaking off (calving), landslides (submarine or coastal), and earthquakes (tsunamis) can all generate waves by disturbing the water. Gravity is a restoring force for waves (like in ocean waves, it pulls the water back to equilibrium after a disturbance), not a generating force that initiates the wave - making process.

Answer:

gravity
