14-21. Why so much oil in Texas?Place the events
in proper order.

• Oil migrates up fissures to form reservoirs.
• Tropical wet/dry climate oceanic rifting leads
  to massive deposits of salt.
• Marine snow deposits on floor of gulf.
• Pangea begins to split Florida detaches from
  Africa, Yucatan from South America, opening up
  the gulf.
• Rockies uplift, leading to massive deposits of
  silt on top of salt.
• AB. Dead plankton cooks under pressure to form
  oil.
• AC. Under pressure from overlying sediments, salt
  begins to flow like magma, and form huge diapirs.
  
• AD. Rising salt diapirs form fissures in the
  overlying rock and sediments.
