Question 1
In the early 1900’s Alfred Wegener developed continental drift theory. Assuming that
continental drift continues, predict how a map of the world one billion years from now will
most likely appear.
Question 2

ent understanding.
The lithosphere, the outer part of Earth, is comprised of
The same continents we have today in roughly the same position.
The same continents we have today but moved about 100 metres in different
directions.
A radically different a
angement of continents and oceans.
A vast ocean with no continents, because continents tend to sink.
the Earth’s crust.
the Earth’s crust and the rigid upper layer of the mantle.

Tectonic plates:
Question 4
The theory of plate tectonics helps explain the distribution of Earth’s volcanoes and
earthquakes. Identify the statement below that most accurately re�ects this.
Questions 5 & 6 relate to the following image.
move at speeds of about 5 to 10 kilometres per year.
are sections of the upper mantle, beneath the crust.
are mostly comprised of partly continental and partly oceanic lithosphere.
are slabs of the continental lithosphere.

Question 5
Convergent plate boundaries are located on the image at
Question 6
Mount Ruapehu in New Zealand (shown at F in the image) is one of the more active volcanoes in
the Ring of Fire. It is part of the Taupo Volcanic Arc, where the Paci�c Plate
is subducting beneath the Australian Plate.
Identify the statement below that most accurately re�ects reasons for this.
Question 7
Identify what type of boundary forms when two neighbouring plates slide past one another.
A, B and C only
C, D and E only
D and E only
A, B, F and G only
Subduction is occu
ing because the Pacific Plate is more dense than the
Australian plate.
Subduction is occu
ing because the Pacific Plate is less dense than the Australian
plate.
Subduction is occu
ing because the Pacific Plate and the Australian plate are
sliding past each other.
Subduction is occu
ing because the Pacific Plate and the Australian plate are
pulling apart.

Question 8
Sometimes plate movement causes two continents to collide.
Identify which two processes are most likely to occur as a result of this collision.
Iceland lies at the boundary of the Eurasian Plate and North American Plate as show below.
A high mountain range forms.

Question 10
Ninety percent of the Earth’s volcanic and earthquake activity occurs along the Ring of Fire.
Some volcanic activity however occurs far away from plate boundaries above hotspots. Of the
following, identify which has volcanic activity linked to a hotspot.
It is located on a spreading ridge
It is located on a hot spot
A rift valley runs through the centre of it
It is less than 10 million years old
An ocean trench is found adjacent to it.

Section B - Short Answe
Question 11
The theory of plate tectonics states that the Earth’s outermost layer is fragmented into slabs
called tectonic plates. Identify the co
ect location of the major plates listed below by adding
labels to the map as indicated in the table.
For example, the Australian Plate has been labelled with the letter D.
A = South American Plate D = Australian Plate G = Philippine Plate
B = Scotia Plate E = African Plate H = Eurasian Plate
C = Antarctic Plate F = North American Plate I = Easter Plate
Question 12
Alfred Wegener proposed the Theory of Continental Drift. This is the idea that the continents
are not stationary but move around Earth's surface.

Identify two pieces of evidence that Alfred Wegener used to support the Theory of
Continental Drift AND explain how each piece of evidence supported his theory.
Evidence Explanation
Geologists have hypothesized that the movement of tectonic plates is related to convection
cu
ents in Earth’s mantle. Once formed, these
ing hot material from deep within the mantle
to the surface.
Question 13
Describe how convection cu
ents work with reference to activity beneath the Earth's surface.

Question 16
Australia was once thought of as simply part of the rapidly moving Indo-Australian Plate, but is
now considered a plate in its own right. The Australian Plate incorporates the entire Australian
continent.
Using the information from your course and Figures 1 & 2 above, explain likely reasons for the
extreme age and stability of the Australian Plate. Refer to changes to the Australian continent
over time and how this can be seen in landforms today.
