Ice wedge
When water seeps into a rock, then freezes and expands, cracking the rock. Ice wedge. An ice wedge is a crack in the ground that forms when water freezes and expands in cold weather.
Mechanical weathering explained in an easy to understand way.
Mechanical weathering
The breaking of rocks without any chemical change, like by plant roots, is called mechanical weathering. Mechanical weathering is when rocks break apart into smaller pieces due to things like plants, water, or wind.
Weathering explained in an easy to understand way.
Weathering
The processes which break down rocks. Weathering. Weathering is when rocks break down into smaller pieces because of wind, water, or temperature changes.
