Troposphere

Why does the troposphere have higher pressure than the mesosphere?


The troposphere is the lowest layer of the atmosphere. It is also denser than the layers around it. That is because of all the weight compressing on it. The mesosphere has less weight compressing on it. The air at higher altitudes has less atmospheric pressure. This is because there are less air molecules, and also a lesser affect of gravity. The troposphere is close to Earth causing there to be more air molecules and a greater affect of gravity. Which makes the pressure higher.

Goals for this Semester.

Hi.
I want to participate more in classes, because in some classes I sit and listen and in some I do participate. I also want to keep up my grades. Especially math. I would probabaly do better if I payed a little bit more attention,and back to my first goal,participated more.



I also want to,(even though this isn't school related), get better at my guitar playing skills. Since I had to stop learning for the play. :'( I will probably have to play everyday,even though I pretty much do, and maybe talk my cousin into showing me a thing or two.



Another goal I have,(still not really school related), is to perfect my dancing for the play....Curtains.. Woo.. I will have to practice my dancing and make sure I get to every practice. And having to dance with a really short person does not help.


One thing that frusturates me about school is teachers that don't explain anything. It annoys me. :p
Bye.
