My Review

Personally, I think I deserve an A on my blogs. I am currently up to date, and my spelling and grammar is good. Sadly, however, Mr. Dunn decides what grade I get, and not me. :(

Favorite Earth Science Topics










Geology: My favorite geology topic was the Mesozoic Era. This is because that was when the dinosaurs were around and I am fascinated by dinosaurs.

Oceanography: My favorite oceanography topic was the submersibles because they allow us to see and view ocean animals.








Meteorology: My favorite meteorology topic was the air masses. This is because I learned to read the weatherman's map for the first time.








Astrology: My favorite astrology topic was the String Theory. This is because it is very intersting to me and it's something I've never heard of before.

3. The Sun is a main sequence star.


4. Next, the Sun will use hydrogen in the layers sorrounding the core and become a red giant. This will happen in 5 billion years.

5. On the picture above, the x-axis is surface temperature and the y-axis is absolute magnitude. The diagonal line in the middle are the main-sequence stars.
