Waves carry energy from one
place to another. What is the
primary cause of waves in lakes
and oceans?
Waves carry energy from one
place to another. What is the
primary cause of waves in lakes
and oceans?
A: wind blowing across the
surface of the water
Wind is the primary cause of
waves in lakes and oceans.
What causes wind?
Wind is the primary cause of
waves in lakes and oceans.
What causes wind?
A: The Earth’s tilt on its axis
causes the sun to heat the
Earth unevenly. Uneven
heating of the atmosphere
causes wind.
