= Frost heaving
{wiki=Frost_heaving}
Frost heaving is a geological phenomenon that occurs when the ground surface is pushed upward due to the freezing and expansion of water in the soil. This process typically takes place in regions with seasonal freeze-thaw cycles. Here’s how it works: 1. **Soil Moisture**: Soil contains moisture, which can be derived from rain, snowmelt, or underground water sources. 2. **Freezing**: When temperatures drop, the water in the soil starts to freeze.
