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, about the different rocks that formed as environmental conditions varied through geological time.
Download and print the Climate through time poster for the classroom.
Printed copies are available from our Online Shop.
Climate through time online is an interactive version of the popular poster map, but includes examples of where you might find some of the rock types in the UK and Ireland.
You can show the different rock-forming environments and processes by either clicking on the geological time Period menu or the sea level/temperature graph. This will change the map of the UK and Ireland to show just the rocks formed during that Period:
