This class is an optional Geology course. Since it is a 400-level class, I assume that you have the prior background in first (and second) year Physics classes and Geology classes(381).

Congratulations - you have completed Geology (GLGY 401-UCAL) Midterm.

You scored %%SCORE%% out of %%TOTAL%%.

Your performance has been rated as %%RATING%%

Your answers are highlighted below.

Question 1

The rate which groundwater flows horizontally through an aquifer is known as...

A	transmissivity.
B	fulidity.
C	storativity.
D	conductivity.

Question 2

Which of the following material typically have the highest porosity?

A	Limestone
B	Diamond
C	Till
D	Sand
E	Granite

Question 2 Explanation:

If you answered diamond, you should bury your head in the sand and see how cool that is... Warning, this test is ONLY recommended for experts in getting the lowest IQ scores.

Question 3

What is the difference between porosity and effective porosity?

A	Porosity is the calculation of porous space that are connected to each other. This allows the flow of fluid across a medium.
B	Effective porosity is the amount of pressurized fluid storage in a a medium above the water table.
C	Effective porosity is the calculation of porous space that are connected to each other. This allows the flow of fluid across a medium.
D	Effective porosity is the calculation of porous space that are in similar volumetric size and shape.

Question 4

Tight packing of grains will result in increase in porosity.

A	False
B	True

Question 5

Hydrology is a specialization in Geology in which we study all forms of fluid movements.

A	True
B	False because we also concerned about hydrochemicals.
C	False because hydrology involves only the study of hydrous minerals.
D	False because we are only concerned about fresh water.

Question 6

What is the global percentage freshwater found in rivers and lakes?

A	0.01 %
B	55 %
C	97 %
D	45 %
E	2%

Question 6 Explanation:

97% of the water is found in the ocean as salt water. 2% is found as fresh water stored in glaciers, ice caps and snow.

Question 7

Pure water is highly compressible.

A	True
B	False

Question 7 Explanation:

It is slightly compressible under very special conditions. Generally water is NOT compressible.

Question 8

A steady system is defined in hydrology and hydrogeology as a system in which the mass input to a system is equal to it's output. If you were to track a single water molecule that entries a steady system, would you expect it to exit the system at some point in time?

A	No, because the transportation of water molecules are impossible under steady conditions.
B	Yes, because steady system may still have a flow rate as long as the input and output is constant.
C	No, because the matter input is equal to the matter output. Hence, the system will not transport actual molecule.
D	Yes, because even in a steady state, the wind and other non-liquid migration can transport the molecule across the system.

Question 9

Which of the following statements best describe the potential evapotranspiration (PET)?

A	It occurs under limited amount of potential energy.
B	It occurs under ideal conditions with unlimited supply of water.
C	It occurs under very high amount of potential energy.
D	It occurs under ideal conditions with limited supply of water.

Question 10

Pure water is most dense at what temperature?

A	50 degree Celsius
B	4 degree Celsius
C	100 degree Celsius
D	0 degree Celsius

Question 11

Groundwater recharge is higher in the mountains.

A	False due to runoff.
B	False due to the elevation.
C	True

Question 12

Majority of usable drinking water in Canadian communities are being derived from what source?

A	Ground water
B	Ice caps (NOT the Tim Horten) and glaciers.
C	Surface water
D	Water hold in the soil

Question 12 Explanation:

While ice caps hold the highest volume of drinking water, our Canadian water supply highly depend on the ground water.

Question 13

Hydraulic conductivity, K is dependent on groundwater temperature.

A	False
B	True

Question 14

Which of the following statements are correct about potential evaporation (PE) and actual evaporation (AE)?

A	AE value is always higher than PE value.
B	PE value is always higher than AE value.
C	Ideally both AE and PE values are equal to each other in most parts of the world.
D	AE is a measurement of evaporation under unlimited supply of water.

Question 15

If I drill a well into the ground and the water started to spill out from it, I can make the assumption that the water... (choose the best answer)

A	has negative pressure.
B	has positive pressure.
C	contaminated.
D	is originating from a stream or an underground storage system nearby.

Question 16

The engineering of water management and distribution is often done by what type of professionals?

A	Petroleum Geologists
B	Engineers
C	Hydrologists
D	Hydrogeologists
E	Environmentalists

Question 16 Explanation:

Hydrologists usually focus on the chemistry if water which address the water natural water distribution. Engineers lacks the background to understand the Geology of the area. Therefore, artificial management of water often done by Hydrogeologists.

Question 17

Joints, fractures, faults and other imperfections in rocks and sediments are considered under the primary porosity calculations.

A	True
B	False

Question 17 Explanation:

Those are secondary porosity features.

Question 18

Near a drinking water well, what would you expect to observe in the subsurface?

A	Heterogeneous aquifers having a constant thickness.
B	Decrease in porosity around the pumping well.
C	Increased in porosity around the pumping well.
D	A cone of depression around the pumping well.
