Rebecca notices a huge crack in a larger boulder in her garden she realizes that the crack was caused by frost wedging .place the steps of the frost wedding process in order

When the air temperature of a region falls below the freezing point of the water (0 ° C), frost may occur. It occurs because the water vapor in the air, falling at night, turns into ice crystals.

Rebecca realized that after a frost, a stone presented a crack that was probably caused by frost. The order that this phenomenon occured for this crack to appear was:

Rain water is stored in rock and seeps into a hairline crack during a rainfall: It is probable that this rock had small fissures, by where the rain water infiltrated and was stored there. The temperature falls below 0° Celsius: As previously stated, frost only occurs when the temperature of a region falls below 0 °C Rainwater in the rock crack freezes into ice: At such a low temperature, the water present in the cracks of the stone froze Because ice occupies more space than water, the ice wedges the crack open: When the water froze, it turned to ice and expanded in size. Ice takes up more space than water, so ice forced the small cracks in the stone to crack. The freeze-thaw cycle continues to deepen the crack until the rock splits into 2 pieces: The freezing causes the ice to expand more and more and this deepens the cracks in the stone.
