Question

How can the creation of ice result in physical weathering? view available hint(s) how can the creation of ice result in physical weathering? ice dissolves the surrounding container. ice scrapes the sides of the container, making it bigger. ice contracts as it forms, allowing a container to collapse. water expands in volume when freezing, exerting pressure on a container. liquid water carries talus into a fracture, which wedges the container open?

Answer 1

Ice plays a very important role in mechanical weathering. The fourth option is the correct answer. WATER EXPANDS IN VOLUME WHEN FREEZING, EXERTING PRESSURE ON A CONTAINER. 

The appropriate name for this type of weathering is frost action/frost shattering/freeze and thaw weathering. This type of weathering occurs in the mountainous regions of the temperate climate were water freezes at night and thaws in the day or summertime. When water freezes it expands by 10% and exerts pressure within the cracks in rocks. Over time this continuous freezing and thawing will cause rocks to break off into angular fragments.
