The new ELI today is 'Building silicates; simulating crystal size during the cooling of magma and during recrystallisation in solid rock'.
This Earthlearningidea is a consolidation exercise to show how cooling/recrystallisation rates might explain crystal size in igneous and metamorphic rocks.
Related activities can be found in the categories 'Igneous processes' and 'Metamorphic processes'.

Earth Learning Idea makes me emotionallly;)
This earth learning idea suggests that the size of silicate tetrahedron increases in size but the distance between oxygen atoms and the central silicon atom is FIXED by atomic physics I am Sorry but this will give a completely false idea of magma crystallisation and lead to misconceptions in the future. Please alter this
