To celebrate Earth Science Week 2015, our geoscience experts have prepared a range of fun and challenging activities to highlight many aspects of how our planet works and put your geoscience knowledge to the test.

Test your knowledge with the Earth Science Quiz, which offers multiple choice questions in three categories:  Easy, aimed at primary school students; Medium, aimed at high school students; and Hard, aimed at adults. There are two sets of questions to try in each category - and a certificate on completion! Here's a taste of what's on offer.
