What is it called when softer rock weathers away and leaves harder rocks behind
The process by which softer, less weather resistant rocks wear away and leave harder, more weather resistant rocks behind
The term erosion could be applied to the weathering of the surface of the earth. As water and the particulate matter it carries sweep over rocks, the softer ones will be worn away, will erode, more quickly than the harder ones. In the event of violent flooding when a massive increase in water flow churns river beds, rocks can be picked up and slammed together. Again it will be the softer materials that will be broken up more than the harder ones.
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.

An arch is typically a result of erosional processes, where softer rock is eroded away, leaving behind harder rock that forms an arch-like structure. It is not typically associated with deposition.
Pedestal rocks are usually formed in desert, when wind erosion wears away softer rock under-laying a harder rock. The harder rock is eroded at a slower rate than the softer rock.

Hard rocks , such as granite, weather more slowly than softer rocks , such as limestone. Differential weathering happens when softer rocks weathers away and leaves harder, more resistant rock behind. The figures below show an example of how differential weathering can shape landscape.
