Abrasion is the process of rocks and sediment wearing away by the actions of water, wind, or ice carrying and rubbing particles against the surface. Ice wedging occurs when water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart over time as the ice expands.

What are some forms of mechanical weathering?
Some forms of mechanical weathering include frost wedging (freeze-thaw cycle), root wedging (roots growing into cracks), abrasion (rock being worn down by friction), and exfoliation (layers of rock peeling off due to pressure release).
Explian the four types of mechanical weathering?
The four types of mechanical weathering are frost wedging (freeze-thaw cycles causing cracks in rocks to expand), exfoliation (peeling away of outer layers due to pressure release), thermal expansion (rocks expanding and contracting due to temperature changes), and root wedging (roots growing in cracks and breaking apart rocks).
What is an example physical weathering?
ice wedging
Ice wedging is brought about by .?
roots absorbing minerals
What cause potholes to form in roadways?
ice wedging
What are the four causes of mechanical weathering?
ice wedging pressure release plant root growth and abrasion
What ice wedging?
wedging ice to a cake at a wedding

What is a types of physical weathering.?
Some types are thermal stress, frost wedging, abrasion, pressure fractures (pressure release), hydraulic action, and salt crystal expansion.
The process by which ice widens and deepens cracks in rocks is called?
ice wedging.
How does ice wedging relate to mechanical weathering?
Ice wedging is a type of mechanical weathering.
What is the process by which ice widens and deepens cracks in rock in called?
The general term for this is "erosion".
What does ice do to rocks?
It breaks from ice wedging
What are the main five agents of physical weathering?
The main five agents of physical weathering are temperature changes, ice wedging, wind abrasion, plant root growth, and abrasion by rock particles. These agents break down rocks and minerals into smaller fragments over time.
How do ice wedging pressure release plant root growth and abrasion cause mechanical weathering?
Ice wedging increases pressure in cracks, causing them to expand when water freezes, leading to mechanical weathering. Pressure release from overlying rock exposes underlying rock to reduced pressure, causing expansion and fracturing. Plant root growth exerts force on rocks, breaking them apart, while abrasion from particles carried by wind, water, or ice wears down rock surfaces over time.

What are some examples of mechanical weathering?
One example is when it rains, and there is a crack in the road. When the crack fills up with water it freezes and the crack will expand. Other examples are ice wedging, abrasion, exfoliation, and thermal expansion.
