Da Who?
a German meteorologist and geophysicist who formulated the idea of continental drift theory.
ALfred Wegener
The portion of the crust that is dense around 2.9 in density and is made up of basalt. It extends up to 7 km in thickness
Oceanic Crust
The earth is broken down into massive slabs known as _____.
PLATE / TECTONIC PLATE
The Alaskan Earthquake is due to the subducting pacific plate underneath the north American plate. This type of plate movement is due to what type of plate interaction?
Converging Plate
The point where plates meet.
Plate boundary
He published ‘The History of Ocean Basins' in 1962, in which he outlined a theory that could explain how the continents could actually drift.

Continental Crust
He proposed the idea about Gondwana, which is composed of today's continents Africa, Antartica, South America, Australia and sub-continents of India
Eduard Suess

Which driving force takes place when a subducting slab sinks and the reset of the slab are pulled which is attached to it?
Slab pull
Which tectonic plate movement caused the great Chilean Earthquake?
Subduction (due to converging plate boundary)
Krakatau Eruption is due to what type of plate movement?

Subduction Zone
