### sense in the lessons

In geography lessons, coastlines change through erosion (waves wearing away cliffs) and deposition (sand building beaches); features include bays, headlands, cliffs, stacks and spits. Countries are compared by length of coastline. In maths there is a famous puzzle: the more carefully you measure a coastline, the longer it seems (the coastline paradox).
