1. The Big Bang Theory (now a law!!)

Before we start with the geologic history of Earth, we need to know how the Earth came into existence and for that matter how did this universe come into existence. So, do a little bit of research into the 'Big Bang' theory, now a law after what Hubble Space Telescope discovered a few years back, and then describe in your own words what this Theory states and how did our solar system come into existence!

You may describe each Stage of the BBT if you wish, as that way it is quite simpler to do so.

2. Geologic timescale on earth

In the reading assignment for this week, there are a number of Eras and Epochs described and before we go into details about each one of them and find out what kind of rocks or habitat existed at that time, let's first check out the Geologic Timescale on Earth.

Describe the different time periods that are in the GT and describe each Era in a short paragraph along with details on its characteristics.

3. Describe one era of your choice!!

Which of the Eras that you described above is meaningful to you? Why? Explain, giving examples and description of the events, organisms and geology related to that Era.
