Why the vegetation on the north facing side of a hill is frequently different from the vegetation on the south facing side of the same hill?

The vegetation on the north-facing side of a hill is often different from that on the south-facing side due to variations in sunlight exposure. The south-facing slope receives more direct sunlight, resulting in warmer temperatures and drier conditions, which can support drought-resistant plants. In contrast, the north-facing slope tends to be cooler and shadier, often retaining moisture, thus favoring species that thrive in these conditions. This difference in microclimates leads to diverse plant communities on either side of the hill.
