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 su(cid:374)"s radiatio(cid:374) The u(cid:374)"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 oceams. All weather (i. e. clouds and precipitation) is confined to the troposphere. The ozone layer protects us from the su(cid:374)"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. The prefix describes the height of the cloud; the suffix describes its appearance. Ex: a high puffy cloud is called a cirrocumulas cloud.
