Plucking is when melt water from a glacier freezes around lumps of cracked and broken rock. When the ice moves downhill, rock is plucked from the back wall. Abrasion is when rock frozen to the base and the back of the glacier scrapes the bed rock.

Abrasion is the wearing down of rock particles by friction and impact as they are transported by water, ice, wind, or gravity. Plucking is when pieces of bedrock are plucked or torn away by flowing glacier ice, usually along fractures or weaknesses in the rock. Both processes contribute to glacier erosion and the shaping of landscapes.

Does Gravity cause abrasion?

Gravity itself does not cause abrasion, but it can indirectly contribute to abrasion by influencing the movement of materials that can cause abrasion, such as rocks or debris. For example, gravity can cause these materials to roll or slide down a slope, which can result in abrasion as the materials interact with surfaces.


Would plucking most likely be the biggest problem for a coastal town?

No, coastal erosion from waves and tides would likely be a bigger problem for a coastal town than plucking. Plucking is a process where rocks are loosened and removed by glaciers or ice sheets, which are not typically found in coastal areas.


What is the ability to withstand scratching and abrasion?

The ability to withstand scratching and abrasion is called abrasion resistance. It measures a material's ability to resist surface damage when rubbed against another material. Materials with high abrasion resistance are more durable and long-lasting.


Wearing something down by friction is called?

Wearing something down by friction is known as erosion. It can also be caused by an abrasion, adhesion, cavitation, and vibration.


What abrasion means in laminate floors?

Abrasion in laminate floors refers to the wearing away or damage to the surface layer of the flooring caused by friction, foot traffic, or other abrasive elements. This can lead to a decrease in the flooring's aesthetic appeal and durability over time. Regular cleaning and maintenance can help prevent and minimize abrasion on laminate floors.
