Hail. when it melts, water can damage the rock.
the nature of the material weathered (shape, size, composition) the nature of the weathering agent the frequency of the weathering agent the properties of the surrounding environment
When rocks are broken down without any change to their chemical compositions it is mechanical weathering. Causes of mechanical weathering are Freezing and melting of water, Abrasion, when the rock is weather by an abrasive agent such as wind and sand, and exfoliation occurs when a rock is brought to the surface.
No ice is an agent of physical weathering
acid precipitation is an agent of -------weathering
chemical weathering
Emission of Infra Red, Ultraviolet and Gama radiation from the sun is why it is an agent of weathering.

what are the agents of weathering
Unloading acts as a weathering agent by breaking bedrock into smaller pieces. This increases the surface area along which chemical reactions can occur, which eventually leads to weathering.
