Erosion is a physical change similar to abrasion.

Abrading is caused by two solids moving by one another and wearing each other down.

Erosion occurs when a fluid passes a solid and removes some of the solid.

The changes caused by using an eraser are primarily physical: Chalk on a chalkboard or graphite from pencils on paper is transferred from the surface erased to the surface of the eraser. Some fairly weak chemical bonds may form between the transferred material and the eraser.
