- ✓The Eiffel Tower grows taller in summer due to thermal expansion
- ✓Height increase can reach up to 15 cm (6 inches)
- ✓Constructed from puddled iron which expands/contracts with temperature
- ✓Temporary and cyclical changes with no structural impact
Yes, the Eiffel Tower grows taller in summer due to thermal expansion, a well-documented physical phenomenon. Here are the key facts:
- ·Mechanism: The tower's puddled iron structure expands when heated, increasing its height, and contracts when cooled.
- ·Scale: The height variation can reach up to 15 cm (about 6 inches) between extreme summer and winter temperatures.
- ·Additional Movements: The tower may also tilt slightly (up to 18 cm) away from the sun as the heated side expands more, and its top can sway by 5-7 cm in strong winds.
These changes are temporary and cyclical, with no impact on the tower's structural integrity.
