Do leaves change position when it is going to rain?

Yes, leaves can change position before it rains. Many plants exhibit a phenomenon called "leaf folding" or "leaf drooping," where leaves fold or droop in response to increased humidity or changes in atmospheric pressure that often precede rain. This behavior helps reduce water loss and can also protect the leaves from excess moisture during rainfall. However, not all plants respond in the same way, and this behavior may vary across different species.
