Which is the fastest spreading ocean?

New ELI today - 'Which is the fastest spreading oceanic ridge? A map-based activity to find the most active oceanic spreading ridge'

This ELI is a measurement and calculation activity to work out which of the oceanic ridges is spreading fastest, based on map data of the ages of the ocean floors. It provides the opportunity for pupils to investigate relationships of distance, time and speed in a novel, geological context. It also allows them to use a linear scale and become familiar with large numbers.
