Archaeology
An amphora
In archaeology we learn about the past from things we find in "digs". In underwater archaeology we learn about the past from maritime finds, usually shipwrecks. The maritime finds can also be dwellings and ports that were once above the water but are now covered by water. Ships sink for many reasons. These include natural disasters such as terrible storms. They can also be caused by problems with the ship or attacks by others. No matter how they happen, along coastlines around the world many thousands of ships have sunk. Ships are lying there as links to the past.
Check that you understand what these words mean in this document Maritime find: a wreck and (or) historical artefact found at sea. Dwelling: a house. Coastline: a line that forms a division between the land and the ocean or a lake. To sink (sunk in the simple past tense): to fall to the bottom.
