Ice can find its way into cracks and fissures of rock when melted to a liquid state. When it refreezes, it expands, prying the cracks further apart. Moving ice can facilitate the abrasion of existing rock into smaller particles by grinding their surfaces against each other. Moving ice can also pluck rock fragments off of existing rock as it moves.

∙ 11y agoin most cases lets say if there is a crack in a rock and water falls in the crack and freezes it would or might push the rock apart because water does expand when it freezes but not by much but sometimes just enough to push the rock apart

Rock particles wear away rock?
Abrasion is when rock particles are wearing away from the rocks surface. This is done by wind, water, and ice in nature.
Does mechanical weathering change a rock size?
Yes, over time. The rock will wear away, and with enough time, mechanical weathering will wear the rock down to sand.
How does water and ice erode rock?
by dissolving it, by getting into cracks and freezing, and by simple friction (wear).
What effect does the hardness of a rock have on the rate at which a rock abrades?
The harder a substance is, the longer it takes for it to erode.
What is Ice wedging brought about?
when water freezes a certain rock and breaks it down..
