Document Summary
There is an equilibrium between incoming radiation and outgoing radiation. Earth i(cid:374)ter(cid:272)epts o(cid:374)l(cid:455) a s(cid:373)all portio(cid:374) of the u(cid:374)(cid:859)s radiatio(cid:374) The u(cid:374)(cid:859)s e(cid:374)erg(cid:455) dri(cid:448)es the h(cid:455)drologi(cid:272) (cid:272)(cid:455)(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.

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. The ozone layer prote(cid:272)ts us fro(cid:373) the u(cid:374)(cid:859)s har(cid:373)ful uv ra(cid:455)s; it is fou(cid:374)d i(cid:374) the stratosphere. Cloud names generally contain a prefix and a suffix.
