Today's new ELI is 'Question you can ask at any rock face 2: erosion'.
Erosion is ‘The removal of solid material, by gravity, water, wind or ice’ and so is the beginning of transportation. Take your pupils to an area of loose rock beneath a rock face, preferably with water-formed gullies leading away – and ask the questions listed in the activity.
Although weathering is distinct from erosion, weathering and erosion usually work together; rocks are weakened by weathering and the weakened material is removed by erosion.
Lots more thought-provoking activities can be found on our website.
