There are 8 layers of the atmosphere. the 4 main layers are troposphere, stratosphere, mesosphere, and  thermosphere. the minor layers are ozonosphere, ionosphere, exosphere, and magentosphere. the troposhere is where weather occurs and most dense. the stratoshere contains most of the ozone layer also jets fly here. mesosphere is where metors burn up and is also the coldest part of the atmosphere. In the thermosphere air molecules can be up to 1 km. apart also the international space staion.the ozonoshere protects us from most of the suns UV rays. the ionosphere helps bounce waves back to Earth. exospheresatelites orbit here. and it has no defined end. Magnetosphere earyhs magentic feild protects eath from solar wind

I wrote 13 post. 3 of my postes were school based and 10 were set by the challenge. i got 6 comments. the one that got the most comments was my rock story i think it got the most because it was a cute story. my rock story was the funnest to write because it was a true story and it brought me back to my childhood. i changed my blog theme once to make it more of my own. i don’t have any widgets. I don’t have any oveseas students.
