Week 9 Lab

 1. What are the significant events in the history of Earth? In lab, we learned about the geological time scale of Earth. We had to list 5 events on a timeline. These events were humans appearing, dinosaurs ruling the Earth, first land plants, first land animals, moon being created. We explored how the moon went through many phases. It was really hot at one point and then it was all ice and snow. The ice and snow melted from the formation of plate tectonics that created volcanos I think.

2. No lecture.

• I learned that Earth was in Snowball Earth at least three times in its history.

• I need more information on Earth's initial formation and why it was so hot.
• Why was Earth so hot in its formation? Like the initial formation?
