The most interesting topics from modules 10 to 12 were measuring geologic time, Mass wasting, weathering, and soil, as well as streams and floods. These chapters taught me how to recognize the impact of natural resources on rocks in the environment. The breaking down, decomposition, as well as the appearance of rocks are impacted by weathering throughout time. The video on mass wasting was interesting. I also liked the demonstration of the weather cycle and drainage pattern. These chapters had a lot of informative components.

The most interesting information I found in these modules was how time is measured with dating rocks. Looking at the picture of the Grand Canyon and being able to compare what it looks like to the idea that they layers are formed on top of each other and when these start tilting then they think that happens after the rocks were formed. I have always watched the history channel and during many documentaries they have stated the age of areas on Earth they found through dating the rocks in the area. I have never understood how they were able to look at a rock and figure out how long that rock has been on earth. Reading how they date them helps me to understand the documentaries that watch.
