Landmass created by Greek god and goddess (7)
I believe the answer is:
pangaea
'landmass' is the definition.
(Pangaea is an example)
'greek god and goddess' is the wordplay.
'greek god' becomes 'Pan' (Pan is an example).
'and' is a charade indicator (letters next to each other).
'goddess' becomes 'gaea' (I am not sure about this - if you are sure you should believe this answer much more).
'pan'+'gaea'='PANGAEA'
'created by' is the link.
Can you help me to learn more?
(Other definitions for pangaea that I've seen before include "Hypothetical early continent, all earth in Greek" , "land now broken up" , "Original supercontinent" , "Original large continent" , "ancient landmass" .)
