The Mohs scale definition of hardness is that a harder material has the ability to scratch a softer material. So (according to the Mohs definition) one material can scratch another one because it is harder.
Dentin is a tissue that is softer than enamel but harder than cementum. It makes up the majority of a tooth's structure and provides support and protection to the inner pulp tissue.
Alloys are harder than the components.
Topaz is softer than quartz but harder than apatite on the Mohs scale of mineral hardness. It has a hardness of 8 on the scale, whereas quartz has a hardness of 7 and apatite has a hardness of 5.
The mineral that is softer than a steel file but harder than glass is typically quartz. Quartz has a hardness of about 7 on the Mohs scale, while glass usually ranges around 5.5, and steel files can be harder, often rated around 6.5 to 7.5 depending on the specific type of steel. Therefore, quartz fits the criteria of being softer than a steel file but harder than glass.

A waterfall. The softer rock erodes faster than the harder rock, creating a drop in the landscape as the water flows downstream. This process over time can lead to the formation of a waterfall where the softer rock has worn away.
