Want to see how Ice really eroded our landscape?
Well have a go at the activity below.
What you will need:
Put the gravel in one tray, sand in another and leave the third empty, fill all three trays with water and freeze overnight.
Once frozen, remove the ice blocks and place on the painted board, push the blocks firmly along the board and see which one 'erodes' the painted surface best, gravel, sand or plain ice.
You are creating your very own glacier scratches or 'striations'.
What does this tell you about glacier erosion? Watch the video below and take the short test at the end.
