Document Summary

Lecture 5: quick review of last time. The p(cid:396)i(cid:373)a(cid:396)(cid:455) output of e(cid:374)e(cid:396)g(cid:455) is heat eleased f(cid:396)o(cid:373) ea(cid:396)th"s su(cid:396)fa(cid:272)e. also a t(cid:455)pe of electromagnetic radiation. On a global scale, input balances output but in diff locations u can have more input than output. More input of energy in day, more output during night. More input in summer, more output during winter. If we look at the global amount of energy input and output we can identify . Whe(cid:396)e o(cid:448)e(cid:396) the (cid:455)ea(cid:396) the(cid:396)e"s (cid:373)o(cid:396)e e(cid:374)e(cid:396)g(cid:455) (cid:272)o(cid:373)i(cid:374)g i(cid:374) tha(cid:374) lea(cid:448)i(cid:374)g as output. The(cid:396)e"s a defi(cid:272)it o(cid:374) a(cid:374) a(cid:374)(cid:374)ual (cid:271)asis, o(cid:448)e(cid:396) the (cid:455)ea(cid:396) the(cid:396)e"s (cid:373)o(cid:396)e output of e(cid:374)e(cid:396)g(cid:455) than input of energy. So(cid:373)e of the su(cid:396)plus e(cid:374)e(cid:396)g(cid:455), gets t(cid:396)a(cid:374)sfe(cid:396)(cid:396)ed (cid:271)(cid:455) (cid:449)i(cid:374)d . 5500 degrees celsius, drives from nuclear fusion occurring interior of the sun. hyfrogen fusing and forming helium. And then u have tremendous amount of e(cid:374)e(cid:396)g(cid:455) (cid:271)ei(cid:374)g (cid:396)eleaed f(cid:396)o(cid:373) su(cid:374)"s su(cid:396)fa(cid:272)e i(cid:374) all di(cid:396)e(cid:272)tio(cid:374)s.
