1. A student notices waves forming on the surface of a lake during a windy day. The waves move across the lake, causing a small boat to bob up and down but stay in the same place. Which of the following best explains how energy is transferred in this situation?

• 1. The wind transfers energy to the water, creating waves that move energy across the lake without moving the water itself.

• The water transfers energy to the wind, pushing the boat across the lake.

• 1. The boat transfers energy to the water, causing waves to move toward the shore.

• The energy from the waves transfers matter, causing the water to move to a new location with the boat.
