Document Summary

There is an equilibrium between incoming radiation and outgoing radiation. Earth i(cid:374)ter(cid:272)epts o(cid:374)ly a s(cid:373)all portio(cid:374) of the u(cid:374)"s radiatio(cid:374). The u(cid:374)"s e(cid:374)ergy dri(cid:448)es the hydrologi(cid:272) (cid:272)y(cid:272)le a(cid:374)d all (cid:449)eather phe(cid:374)o(cid:373)e(cid:374)a o(cid:374) earth. Nearly all of the e(cid:374)ergy a(cid:448)aila(cid:271)le at earth"s surfa(cid:272)e (cid:272)o(cid:373)es fro(cid:373) the su(cid:374). Balance what comes out, comes in. We don"t have a balance anymore due to the gasses since they prevent some heat and radiation from leaving (co2) It is composed of nitrogen (78%) and oxygen (21%): 99% -> 2 gasses, the remaining 1% consists of water vapour, carbon dioxides and other trace gasses. Water vapour in the atmosphere can result in cloud development and the formation of precipitation. Water vapour comes from evaporation from the oceans. All weather (i. e. clouds and precipitation) is confined to the troposphere.
