Planet Earth's Nine Lives quiz by Tiki the Penguin     

See what you know about our planet's limits. If you've read my Planet Earth's Nine Lives guide, you should find this quiz quite easy. Remember that with multiple choice questions [square buttons], you need to tick all the right answer boxes to score! I've added some notes or hints (pale blue) in many of the questions.
The music tracks you can choose to play in each question are by Lino Rise (thank you!).
