Earth systems unit changed

In the latest version of Blueprint, we have changed the key concepts in the Earth Systems unit in year 8.  These were: rock cycle and water cycle. Now there is a new key concept 'Earth processes', and this is joined by 'Potable water' which moves down from year 9.

Why? First, the rock cycle is covered in KS3 geography, so it seems to be duplication to make it a key concept in science. Instead we have gone for a deeper understanding of how energy drives process inside and on the surface of the Earth. The water cycle plays a very small role in biology at GCSE, with a limited amount of knowledge, so we reasoned that it does not deserve the status of a key concept.
