What is frost ? How does it causes weathering ?
Answers
Answer:
Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor to ice as the water vapor reaches the freezing point.
One example is called frost action or frost shattering. Water gets into cracks and joints in bedrock. When the water freezes it expands and the cracks are opened a little wider. Over time pieces of rock can split off a rock face and big boulders are broken into smaller rocks and gravel.

Answer:
frost is the deposit of small white ice crystals formed on the ground or other surfaces when the temperature falls below freezing.
Frost weathering occurs in the presence of water, particularly in areas where the temperature is near the freezing point of water. ... When water freezes, it expands, so when liquid water seeps into a crevice in the rock or soil and freezes, its expansion can cause deeper cracks in the rock and eventually break pieces off.
