What happens to the Eiffel Tower each winter regarding its height?

The correct answer is that the Eiffel Tower shrinks by 15 centimeters during the winter. This phenomenon occurs due to the thermal expansion and contraction of the iron used in the tower's construction. When temperatures drop in the winter, the metal contracts, causing a slight decrease in height. Conversely, during the warmer months, the metal expands as temperatures rise, which can cause the tower to grow a little taller. This fluctuation in height is a normal physical response of materials to changes in temperature. The change is temporary and reversible, meaning it does not affect the overall structural integrity of the tower.
