Well Question
1.As a driller, you are considering a location
for a new fresh water well. Explain the two
characteristics the geological materials
must have to produce a flowing artesian
well that provides a clean water supply.
2. With the aid of a fully labelled diagram,
briefly describe the conditions necessary
to produce a flowing artesian well.

Interaction of the Spheres
Describe how the interaction of two of
Earth’s spheres resulted in the formation
of oil.
Describe how the interaction of the
hydrosphere and the geosphere combine
to create the landforms of Earth

Mineral Test Question
Describe how a geologist would go
about testing the specific gravity of a
mineral
Explain what is meant by the Mohs
scale and how it is used to determine
the hardness of a mineral

Sedimentary Rock Question
Explain the difference in the
formation of a clastic and a chemical
sedimentary rock. Use an example of
each.

Igneous Rock question
Remember this chart

Metamorphic Rock Question
Describe the difference between
Regional and Contact Metamorphism
Explain how both regional and contact
metamorphism can occur at a subduction
zone.
Explain how sedimentary rocks may
eventually form metamorphic rocks.

Layers of the Earth
Geologists represent the interior of Earth
as having different physical layers.
Explain the importance of radioactive
decay and gravitational forces in the
segregation of Earth’s interior.

Oil Trap Question
Draw a cross-section of a fault-type oil
trap. Label the cap rock, reservoir rock,
and the location of oil, natural gas, and
water. Indicate on the cross-section the
best drill hole location.
Can you do the same for an anticline trap
A large oil reservoir was discovered in a
deformed sedimentary basin located in a
shallow ocean. Use a labelled diagram to
show how the oil is trapped and indicate
on the diagram the best location for
drilling a well.

Fossilization question
Mold and Cast Carbonization
Petrification
Trace Fossils
Explain two ways a beetle could become
fossilized.
Describe what is meant by
carbonization.

Deposition and Erosion
Explain how groundwater can provide
both erosional and depositional
features on Earth

Evidence for Plate Tectonics
Recently, linear chains of volcanoes,
metamorphic rocks, and numerous
outcrops of rhyolite and granite were
found on a planet. Reverse faulting was
also observed. Describe three features of
the plate tectonic environment on this
planet.
A range of mountains is found on
Australia’s east coast. With reference to
plate boundaries, explain how this
mountain range may have been formed.

Evidence of Tectonics (cont.)
With the aid of a labelled diagram, explain
how hot spots can be used to support the
Theory of Plate Tectonics.
How can magnetic reversals and
paleomagnetism be used to give evidence
for tectonics
Alfred Wegener’s Theory of Continental
Drift failed to explain how the continents
actually moved. How does the current
Theory of Plate Tectonics explain the
movement of continents today?
