About this Exam
Prepare with the Association of State Boards of Geology ASBOG 1 Practice Exam practice quiz. This question bank includes 10 questions covering property, soil, direct, association, and state. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
The direct shear test is used to measure which property?
Explanation:
The direct shear test evaluates how much shear resistance a soil, rock material, or a planar discontinuity can provide along a defined sliding plane. In the test, a normal load is applied while a shear load is gradually increased until the plane fails, giving the shear strength at that normal stress. By doing tests at several normal stresses, you can determine the parameters that describe shear strength, typically cohesion and the internal friction angle, through the Mohr-Coulomb relationship. This focus on resistance to sliding on a plane is why the test is used to characterize shear strength properties, rather than density, permeability, or thermal conductivity, which require different tests.
Question
2
Ground-penetrating radar is commonly used in environmental site investigations to?
Explanation:
Ground-penetrating radar relies on sending high-frequency radio waves into the ground and recording reflections from subsurface interfaces with different dielectric properties. Buried drums create a strong contrast with surrounding soil, producing a noticeable reflection that can be detected and mapped at shallow depths. In environmental site investigations, this makes GPR a quick, non-destructive way to locate potential sources of contamination like buried drums before intrusive digging or sampling. It’s not used to measure soil pH or groundwater salinity, which require chemical analyses, nor to assess rock strength, which needs mechanical testing; those tasks rely on different methods. So locating buried drums is the best fit for GPR in this context.
Question
3
Consolidation test evaluates which soil property?
Explanation:
Consolidation tests focus on how a soil decreases in volume over time when a sustained load is applied, as water is squeezed out of the pore spaces. This process directly governs how much a foundation or soil fill will settle in the long term. By measuring vertical settlement under controlled drainage, you obtain the soil’s compressibility and rate of consolidation, which are used to predict settlement potential for design. This is different from permeability (which looks at fluid flow through soil), shear strength (which concerns resistance to sliding under shear), or compaction behavior (which is about densification under energy input). So the test is best for evaluating settlement potential.
Question
4
Which type of water has never circulated in the hydrologic cycle?
Explanation:
The main idea here is distinguishing water sources by where they originate and whether they have been part of the hydrologic cycle. Water from the atmosphere and precipitation has clearly circulated through evaporation, condensation, and precipitation. Atmospheric water vapor is continually cycling in the air, and meteoric water describes water derived from precipitation that enters the cycle. Water trapped in rocks as they form (connate) represents ancient water that was incorporated at deposition and has not been part of surface–atmosphere cycling since, so it’s not part of ongoing cycling in the same way. Juvenile water comes from deep within Earth’s mantle and is released by magmatic processes; it has not passed through the surface/atmosphere hydrologic cycle, so it’s the water type that has never circulated in that cycle.
Question
5
Which seismic wave travels through both solids and liquids?
Explanation:
Seismic wave propagation depends on whether the medium supports shear. The wave that travels through both solids and liquids is the compressional (P) wave. P-waves move by compressing and expanding the material in the direction of travel, and this mechanism works in substances that have bulk rigidity, including liquids. Liquids lack shear strength, but they do have bulk modulus, so they can carry these compressional waves. In contrast, shear (S) waves rely on the medium’s ability to support shear motion and cannot propagate through liquids, so they stay within solids. Surface waves travel along interfaces and are not the wave type responsible for moving through liquids. So the wave that traverses both solids and liquids is the compressional P-wave.
