Earth's climate has changed throughout the billions of years of our planet's geological history. Evidence for past climates — including the extreme conditions linked to mass extinctions — can be found in the rocks around us.
Many rock-forming environments are directly influenced by climate. Were your local rocks formed in a desert, or a tropical swamp, or on a cold seabed? And what evidence can we find to show that these environments really existed millions of years ago? You can now find out, using this new poster which illustrates the links between our planet's changing climate, and the different rocks which formed as environmental conditions varied through geological time.
We will be developing interactive resources and classroom exercises based on the poster later this year, so keep checking this page!
