This app has three sections; Something about Rocks, Identify Rocks and Game.

Section 1: Something about Rocks
The first section contains information about the three types of rocks; igneous, sedimentary and metamorphic rocks. The information here is useful while identifying rocks in Section 2 and playing the game in Section 3.

Section 2: Identify Rocks
In this second section, you choose a rock from the nineteen shown and answer some questions related to the rock chosen. If all the answers are correct, the name of the rock is displayed. If not, you can try again and check all the answers.

Section 3: Game
In this timed game, you choose the odd one out from a set of descriptions and image of a rock. When the choice is correct, the score increases by 1. The challenge is to choose as many correct odd ones out before the time runs out.

I would like to thank the Geology Departments of University of Malaya and National University of Malaysia for allowing me to take pictures of some of their rock samples.
