Air is a FLUID A fluid can be a liquid or a gas Like water, air FLOWS and FORMS MASSES (AKA “blobs”) &bih=453&tbm=isch&prmd=imvns&tbnid=GoJeomeIyRjrsM:&imgrefurl= m/home/saf/page_170&docid=HZ_dFhNKoLVydM&imgurl= /cec_students_swimming_lake_michigan.jpg&w=325&h=246&ei=gFF7UKOTApOy8QSe9YHABg&zoom=1& iact=hc&vpx=501&vpy=2&dur=1851&hovh=195&hovw=258&tx=137&ty=87&sig= &page=11&tbnh=152&tbnw=199&ndsp=13&ved=1t:429,r:36,s:100,i:112

VOCABULARY 1.Air Mass = 2.Tropical = 3.Polar = 4.Continental = 5.Maritime = 1.a “blob” of air with similar properties 2.Near equator (warmer) 3.Near poles (colder) 4.Over land (dry) 5.Over water (humid)
