Well Question

1.As a driller, you are considering a location for a new fresh water well. Explain thetwo 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.

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 trapA 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.

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?
