Geological time gaps - unconformities

'Filling the gap – picturing the unconformity ‘abyss of time’? Working out what happened during unconformity time gaps'


This activity gives pupils a method to help them to visualise the enormous time-spans between the upper and lower layers of unconformities.

Many more activities about Geological time, or 'deep time' can be found on our website.

Factors controlling metamorphism

The new ELI+ today - 'Metamorphic processes: controlled by depth, temperature and pressure: what factors control metamorphism?'

In this Earthlearningidea, pupils identify the appropriate zones on a pressure/temperature graph for a range of metamorphic processes. It is a useful revision activity on metamorphism. 

Many more activities, not all ELI+, can be found by using the alphabetical index or the search engine on our website.

How long do Earth events take to happen?

'How long does it take? – quick to very, very, very slow; sorting out Earth events according to the time they take'


This Earthlearningidea asks pupils to subdivide Earth processes according to the time they take. The answers which are likely to result from the discussions are given in the activity. Some Earth processes happen very quickly, whilst others act very, very slowly.

Other activities related to Geological time can be found on our website.

What did kill the dinosaurs?

New ELI today  'Extinction mystery; what did kill the dinosaurs?'

This activity is a card sorting exercise involving deciding which factors might have contributed to the extinction of the dinosaurs.

There are many misconceptions about how dinosaurs became extinct. The mystery encourages pupils to put evidence into a sequence so that they can explain some of the possible causes of the extinction.

Many more activities can be found about dinosaurs by using the search engine or alphabetical index on our website.

How partial melting helps to explain igneous rocks

Comparison of a model with reality to develop understanding of the partial melting process; 'Partial melting model and real rock' - an ELI+ activity.


This ELI is a consolidation exercise on partial melting, to ensure that students understand how a model mirrors processes in real rocks. The partial melting process can be directly linked to the key rock-forming minerals by reference to Bowen’s Reaction Series, which is explained in the activity.

Other Earthlearningideas about igneous rocks for all ages of pupils, can be found by using the search engine or alphabetical index on our website.
