As the plates scrape against each other, one goes under the other (for instance, the Pacific plate is inching it's way under the North American plate) causing tension to build along that point. At some point, enough tension builds that the upper plate "springs" back up, possibly causing an earthquake, and possibly causing a tsunami. This is what caused the Indonesian tsunami 12/26/2004.
This process is called abrasion. It occurs when rocks rub or scrape against each other, causing the surface to wear down and small pieces to break off due to the friction and force generated during the interaction.
Continental glaciers smooth the landscape because the immense weight and pressure of the ice sheets scrape and erode the underlying rocks and soil as they slowly move across the land. This process, known as glacial erosion, acts like sandpaper, grinding down the surface features and creating smooth, flat expanses of land. Additionally, the movement of the glacier can carry and deposit the eroded material, further reshaping the landscape.
Erosion can occur through the actions of water, wind, and ice. Water erosion can happen from rainfall, rivers, or waves wearing away soil and rock. Wind erosion occurs when wind carries away loose particles of soil and sediment. Ice erosion happens when glaciers move and scrape against the land, wearing it down over time.
Glacial erosion occurs primarily through the processes of plucking and abrasion. Plucking happens when the glacier picks up rocks and sediments as it moves, while abrasion occurs when these materials scrape and grind against the rock surface, wearing it down. Together, these processes shape the landscape by carving out valleys, creating deep basins, and smoothing the underlying bedrock.
The three main types of glacial erosion are plucking, abrasion, and quarrying. Plucking occurs when rocks are lifted and carried away by the moving glacier. Abrasion happens when rocks and sediment carried by the glacier scrape against the bedrock, wearing it down. Quarrying involves the glacier breaking off and carrying away large chunks of bedrock.

to remove impurities so that it can be more reactive
earthquakes happen
They could get damaged, if you scrape them with enough force.
the tectonic plates of the earth move and scrape against each other
So if they fall they won't scrape their knees. But they were invented because in 1919 when people(mostly men) jumped to spike the ball, they would scrape their knees against the net.
Earthquakes
Yes paint comes off a car but only if you scrape it against something.
The earthquake occurred at a convergent boundary between the Nazca and South American plates which are converging at a rate of approximately 80mm / year. The dense oceanic crust of the Nazca plate is being forced under or subducted beneath the less dense continental crust of the South American Plate.
As an iceberg - or glacier - moves across land, it will scrape against it, causing it to weather/erode the land.
