Geological Time Activities

          From the geological history, I've learned lot of things that I haven't know or understand before. I've learned that there are stages or periods before we came, and what we are now in this world. At first, the Earth formed when bacterias are around, animals (either small or big), plants, dinosaurs, monkey then suddenly, we, humans appeared. I've also learned that the Earth changed about million years ago, and continents landed to different places, joined together, and spread out again. There are four type of Eras in geologic time that tells us about stages of how we appeared and lived. I've learned that Alfred Wegener, a young German Earth Scientist is searching and finding an evidence about the drifting of continents. The point of learning geological history is to help us understand about what happened before we came, and to think what we can do, now that we know the history or where we came from, how we became a human, and continue to learn about the Earth, and theories' of Scientists.
