The Eiffel Tower, one of the most iconic structures in the world, actually grows taller in the summer. Due to the heat, the metal of the tower expands, causing it to grow by up to 6 inches (15 centimeters). This is because iron expands when it is heated, and since the Eiffel Tower is made primarily of iron, its height can fluctuate with the temperature. In colder months, the metal contracts, and the tower returns to its usual height.

How Temperature Affects the Eiffel Tower's Height

The expansion and contraction of materials due to temperature changes are known as thermal expansion. For the Eiffel Tower, this phenomenon is most noticeable in summer when temperatures rise. As the iron heats up, the individual molecules within it move more and take up more space, leading to the expansion of the tower’s structure. This effect, while subtle, demonstrates how large structures are affected by the environmental conditions around them and is a great example of physics in action in everyday life. Shutdown123
