1. What is the minimum education requirement to qualify for a
Professional Geoscientist (PG) license in Texas?
A. Associate degree in geology
B. Bachelor’s degree in geoscience or related field
C. Bachelor’s degree with 30 hours in geoscience courses
D. Master’s degree in geology
A bachelor’s degree with at least 30 semester hours in geoscience is
required by the Texas Board of Professional Geoscientists.
2. Which Texas agency is responsible for licensing professional
geoscientists?
A. Texas Department of Licensing and Regulation
B. Texas Commission on Environmental Quality
C. Texas Board of Professional Geoscientists
D. Texas Department of State Health Services
,The Texas Board of Professional Geoscientists (TBPG) oversees licensure
and regulation of geoscientists in Texas.
3. The Mohs scale is used to determine:
A. Rock permeability
B. Mineral hardness
C. Geologic age
D. Plate movement
The Mohs scale is a tool for ranking minerals based on their ability to
scratch one another, which indicates hardness.
4. Which rock type is formed through metamorphism?
A. Basalt
B. Limestone
C. Schist
D. Sandstone
Schist is a metamorphic rock formed from shale or other precursor rocks
under heat and pressure.
5. A geologic unconformity represents:
A. A mineral deposit
B. A gap in the geologic record
C. A fault zone
D. An igneous intrusion
An unconformity indicates a period during which deposition stopped,
erosion removed previous layers, and then deposition resumed.
6. Which of the following geologic structures is commonly associated
with petroleum traps?
, A. Normal fault
B. Syncline
C. Anticline
D. Dike
Anticlines, or upward-arching folds, often trap hydrocarbons beneath
impermeable rock layers.
7. In groundwater hydrology, the water table is defined as:
A. The bottom of an aquifer
B. The upper surface of the saturated zone
C. The unsaturated zone
D. A confined aquifer
The water table marks the top of the zone where all pore spaces are
saturated with water.
8. Darcy’s Law is used to describe:
A. Soil erosion
B. Groundwater flow
C. Seismic wave velocity
D. Plate tectonics
Darcy’s Law calculates groundwater flow rate based on permeability, area,
and hydraulic gradient.
9. A fault in which the hanging wall moves downward relative to the
footwall is called:
A. Reverse fault
B. Normal fault
C. Strike-slip fault
D. Transform fault
