  15. Tidal Heating Activity

  16. Tidal Heating Activity • Stretching elastic bands! • Changing stretching = friction = heat • Gravity stretches Moons = tidal force • Changing tidal forces also cause heat • Certain arrangements result in lots of stretching

  20. Summary • Some moons are far from the Sun but are heated somehow • Gravity stretches moons = tidal force • Changing tidal forces provides heat by friction • Heated moons can have volcanoes, geysers, and oceans! • Tidal heating means water can be a liquid even in places far from the Sun.Where there’s water, there might be life!Follow the water!
