Week 9: The History of Earth

1. What did you do in lab today? 

This week in lab, we talked about the creation of many things that occurred in our planet's history: the appearance of humans, dinosaurs ruling the Earth, first land plants, first land animals, and the creation fo the moon. To further our understanding of this timeline, we looked at Earth's history projected onto a 24-hour clock, which depicts many different factors and when they first appeared on Earth. In addition to this, we began to speak about plate tectonics and the kinds of effects earthquakes and volcanoes have on the Earth. 

2. What did you learn in Thursday's lecture?

In Thursday's class, we took our Space Content Assessment. 

3. Pressbook Chapter 15: History of Earth 

• In this chapter, I was able to learn about the timeline of the history of Earth. I had never before seen it laid out in this way, and I think it is because of that that I was able to truly grasp the concept. 
• I think the most helpful part of this chapter was the diagram of the 24-hour clock, because it put into perspective how quickly some things happened and how much time elapsed before some of the other events happened. 
• At this time, I think I could use some in depth conversations about plate tectonics and what is actually occurring when they begin to move. 

3.What questions, concerns, and/or comments do you have?

This week in class was interesting to me, because I really enjoyed talking about all the things that came before us humans, and it was insanely shocking to hear how long ago this all took place.
