I use finite element analysis software to figure out how glaciers can dig out the bedrock they slide over (in Earth Systems Science). This is an important but spatially uneven mechanism of geomorphology that is greatly influenced by the pre-brokenness of the otherwise continuous intact rock, as well as drainage of summer meltwater which can speed up the flow of ice. The faster ice flows in a warming world the less of it there tends to be on land.
