Cold Environments

Our planet is no spring chicken. 

Evidence shows it's been around for about 4.6 billion years (that's 4600 000 000 million years!) 

This is quite literally an unimaginable length of time. Our brains equipped to plan ahead in seasons and years simply can't comprehend how long this really is. To get this idea across some geologists refer to it as 'Deep Time.'

As the course goes on TJJ will be posting his lesson notes here.

And the scheme of work for the topic is here.

Please let TJJ know if this does not work for whatever reason!
