Alfred Wegener in 1912 proposed the continental drift theory, which is a pioneer to other theory of sea floor spreading
Introduction
Alfred Wegener in 1912 proposed the continental drift theory, which is a pioneer to other theories such as sea floor spreading (Hess), Plate Tectonics Theory (Holmes) or Plate tectonics theory (Wegener).

Main Body
Continental Drift Theory:
Refers to constant slow movement of continents over hundred of years
Earlier all the continents were together → large surrounded by ocean → Panthalassa
Continents drifted to form 'Laurasia' & Gondwana land separated by Tethys Sea
Evidence:
1Sea saw fit of Crete & Negillo fits well in the western coast of Africa
2Gondwanan deposits & amoral fossils
Fossils of Eden & Lemurs are found in earthwide Laurasian continent
Beptic similar way of origination
Places Deposits:
Glacial deposits occur at 6 landward forming Gondwanna
4Gold coast
Mexican gold is supposedly connected to gold coast of India
Smokey gold properties & promise had no gold courses
Forces Responsible:
1Pole-fleeing force → continents drifted to avoid the polar regions, leading to their movement
2Tidal force → Alfred Wagner believed the gravitation pull of sun & moon are so strong to create continental drifters
Continental drift theory had certain limitations as the forces responsible been lack empirical evidence but this theory led to 'Plate Tectonics Theory' by Birtle, Morgan & McKenzie, wheich is widespread in explaining volcanic explosions & lecture Glyptic.
