What causes rolling hills to have milder weather compared to high deserts?

The reason rolling hills have milder weather compared to high deserts primarily relates to low temperature variability. Rolling hills typically feature a more diverse microclimate due to their varying elevations and vegetation. This diversity allows them to maintain more consistent temperatures throughout the day and year. In contrast, high deserts experience greater temperature extremes, with hot days and cold nights due to their elevation and lack of significant vegetation.

Factors like elevation, which influences air pressure and temperature, play a crucial role in weather patterns. The presence of plants and trees in the rolling hills provides shade and contributes to moisture retention in the soil, further moderating temperatures. These factors together create a more stable climate pattern in rolling hills compared to the harsh conditions often found in high desert regions.
