International Earth Science Olympiad Mock (Set 1)

Hello Everyone! My name is Lilian Schleret, and I participated int the IESO 2016 Mie (Japan) as  a student where I won a Bronze Medal.

To help you preparing for the IESO,  I have prepared a set of questions comprised of 100 questions. For the first 50 question, there will be only ONE answer. Then, there will always be at least one good answer and one wrong. Try not to cheat by the way. In Set 1, I will be providing 30 questions. Rest of the questions will be provided very soon. Good luck!
