Geologic History
What was the first ancient mountain range in Canada?
Canadian Shield
One piece of evidence of continental drift is the way that South America fits with this continent
Africa
At the centre of the Earth, is this part which is the hottest and made mostly of iron
Core
When two plates move toward each other and collide it is called what type of boundary
Convergent
A continuously active lava lake sometimes called the "gateway to hell" exists in this country
Ethiopia
This landform (not range) was created when the west coast of Canada began folding
Western Cordillera
The Indian sub-continent collided with Eurasia to create this natural feature
The Himalayas
The middle fo the earth composed mostly of a thick liquid called magma
Mantle
When two plates rub against each other moving in opposing directions it is called which type of boundary
transform
Iceland was formed by this unique geological process
Magma Plume
This old mountain range was created when the North American plate collided with the Eurasian Plate
Appalachian Mountains
This geologist is responsible for the continental drift theory
Alfred Wegener
The outer most layer of the earth's structure made of massive plates
Crust
When plates move away from each other creating rift valleys and volcanoes it is called what type of boundary
Divergent
The earth is separated into this many MAJOR Plates
7
These local natural features are scooped out by retreating glaciers
Great Lakes
Coral found in the Great Lakes region prove that this area was once what?
An Ancient Sea
The rocks in the mantle are in a constant cycle which causes the heat to rise and the fall back to the core
Convection
When an oceanic plate collides with a continental plate, its density forces it down creating this type of boundary
Subduction
Volcanoes help to keep heat in the atmosphere by giving off this
Carbon Dioxide (CO2)
Ending over 500 million years ago, this oldest era saw the beginning of the Shield, but most of the world was ocean
Pre-Cambrian Era
The name of one of the fossil types found in South America and Africa
Glossopteris and Mesosaurus
The technical term for the crust and the uppermost portion of the mantle is called the
Lithosphere
A well-known transform boundary exists in California named what
San Andreas Fault
The oldest living things on Earth are called this
Stromatolites
