The proposed supercontinent
that began to break apart 200
million years ago and formed
the current landmasses.
What is Pangaea?
This is the number of years ago
that Pangaea began to break
apart.
What is 200 million years?
The first supercontinent… that
we know of!
What is Rodinia?
This is the number of years
ago that Rodinia began to
break apart.
What is 750 million years?
People didn’t believe that the
continents broke apart because
Wegener could not provide a
BLANK to explain how it
happened.
What is a mechanism?
Organic rocks from which
petroleum is generated. Oil traps
need these.
What is a source rock?
A type of petroleum trap where a
fold in the sedimentary strata,
resembling an arch, allows oil
and gas to accumulate.
What is an Anticline Trap?
A necessary part of an oil trap.
This type of rock is impermeable
and hence keeps upwardly
mobile oil and gas from escaping
at the surface.
What is a cap rock?
The major oil and gas bearing
area in Hibernia.
What is the Jeanne d’Arc
Basin?
These oil traps form when strata
are displaced in such a manner as
to bring the dipping reservoir
rock into position opposite an
impermeable rock bed.
What are Fault Traps?
The zone that makes up western
Newfoundland and is the
Northernmost part of the
Appalachian mountains.
What is the Humber Zone?
The central geological zone of
Newfoundland is known as
this and was created by the
remains of the Iapetus Ocean.
What is the Central Volcanic
Belt?
The zone in the East Coast of
Newfoundland that contains
rocks identical to ones in Africa.
What is the Avalon Zone?
A warm tropical sea that formed
the Central Volcanic Belt when
the continents surrounding it
squeezed the ocean crust
together.
What is the Iapetus Ocean?
A long, narrow zone where
one lithospheric plate
descends beneath another.
What is a Subduction Zone?
A continuous mountainous
ridge on the floor of all the
major ocean basins.
What is an Oceanic Ridge?
A long, narrow trough
bounded by normal faults.
What is a Rift Valley?
A chain of volcanic islands
generally located a few hundred
kilometres from a trench, where
there are active subductions of
one oceanic plate beneath
another.
What is a Volcanic Island
Arc?
If the youngest seafloor is
found at the ridge crest then
BLANK would be found at
the continental margins.
What is the Oldest Seafloor?
No part of the ocean floor that
has been dated exceeds this
date.
What is 180 million years old?
What is this
What is this ancient aquatic organism?
Hint: Their fossils are limited to eastern South
America and Southern Africa.
What is the Mesosaurus?
What is
What is this type of petroleum trap?
What is a Salt Dome?
These are all types of this
petroleum trap.
What are Stratigraphic
Traps?
What is this mineral?
What is a diamond?
What type of boundary is this?
What is a Transform Fault
Boundary?
