The olive tree  is a small tree.
Its scientific name is Olea europaea.
A long time ago, it came from  the coastal areas of the eastern Mediterranean, from Syria and the maritime (next to the sea) parts of Asia Minor and northern Iran at the south end of the Caspian Sea.
It has been farmed for a very long time.
The Ancient Greeks were farming it.
They spread the trees to the western part of the Mediterranean.
 
Olive trees like soil with lots of chalk in it.
They grow best on limestone slopes and crags in coastal climate.
