Questions and Answers
  • 1. 

    Both Both quartz and fluorite come in a variety of colors.  Because they both share some of the same color varieties, they are often mistaken for each other.  In order to tell them apart, a hardness test must be done.  In a hardness test, what result will show the difference between quartz and fluorite?

    • A.

      Diamond scratches quartz and fluorite

    • B.

      Quartz scratches talc

    • C.

      Fluorite scratches talc

    • D.

      Apatite scratches fluorite

    Correct Answer
    D. Apatite scratches fluorite
    Explanation
    Apatite is a mineral that has a higher hardness than fluorite. When conducting a hardness test, a mineral with a higher hardness will scratch a mineral with a lower hardness. Therefore, if apatite scratches fluorite, it indicates that fluorite is softer than apatite. This can be used to differentiate between quartz and fluorite, as quartz has a higher hardness than fluorite and would not be scratched by apatite.

    In northern states such as Colorado and Minnesota, holes and cracks often form on the highways and roads.  Which of the following would most likely be the cause of these pot holes in the road?

    • A.

      Heat turning sedimentary rock in the road into metamorphic rock

    • B.

      Water freezing and thawing inside cracks in the road

    • C.

      Oxygen reacting with iron on the surface of the road

    • D.

      Volcanic activity producing pressure at the road’s base

    Correct Answer
    B. Water freezing and thawing inside cracks in the road
    Explanation
    Water freezing and thawing inside cracks in the road is the most likely cause of the potholes. In northern states such as Colorado and Minnesota, the temperature frequently fluctuates above and below freezing point. When water seeps into cracks in the road and freezes, it expands, exerting pressure on the surrounding material. As the ice thaws, the pressure is released, causing the material to weaken and break apart, eventually leading to the formation of potholes. This freeze-thaw cycle repeated over time can further widen and deepen the cracks, exacerbating the problem.

    Which of the following most promotes chemical weathering in limestone?

    • A.

      Freezing water

    • B.

      Running water

    • C.

      Blowing wind

    • D.

      Growing roots

    Correct Answer
    B. Running water
    Explanation
    Running water promotes chemical weathering in limestone because it carries dissolved acids and other chemical agents that react with the minerals in the limestone, causing them to break down and dissolve. The constant flow and movement of the water allows for a more efficient and widespread distribution of these chemical agents, accelerating the weathering process. Additionally, the physical force of the water can also contribute to the mechanical weathering of the limestone, further aiding in its breakdown.

    There was one month of heavy rain in the hill country.  A portion of one of the highest hills broke away and slid down the hill.  What is the name of the process that allowed gravity to carry the soil down the hill?

    • A.

      Deposition

    • B.

      Weathering

    • C.

      Uplift

    • D.

      Erosion

    Correct Answer
    D. Erosion
    Explanation
    The process that allowed gravity to carry the soil down the hill is erosion. Erosion refers to the gradual wearing away and removal of soil, rock, or other materials by the action of water, wind, or ice. In this case, the heavy rain caused the soil on the hill to become saturated and unstable, leading to a portion of the hill breaking away and sliding down. This is a clear example of erosion in action.

      Condensation

    • B.

      Erosion

    • C.

      Weathering

    • D.

      Compaction

    Correct Answer
    A. Condensation
    Explanation
    The rock cycle is a continuous process in which rocks are formed, broken down, and reformed. The processes involved in the rock cycle include weathering, erosion, and compaction. However, condensation is not a part of the rock cycle. Condensation is the process by which water vapor in the air turns into liquid water, forming clouds. It is not directly related to the formation or transformation of rocks. Therefore, the correct answer is condensation.

    According to the figure below, heat and pressure can turn which of the following rocks into metamorphic rocks?

    • A.

      Sedimentary

    • B.

      Igneous

    • C.

      Both a and b

    • D.

      Neither a nor b

    Correct Answer
    C. Both a and b
    Explanation
    Heat and pressure can turn both sedimentary and igneous rocks into metamorphic rocks. Sedimentary rocks are formed from the accumulation and compaction of sediments, while igneous rocks are formed from the solidification of molten magma or lava. When these rocks are subjected to intense heat and pressure, their mineral composition and texture can change, resulting in the formation of metamorphic rocks. Therefore, both sedimentary and igneous rocks have the potential to undergo metamorphism.

    All of the following conditions in Earth can cause metamorphic rocks to form EXCEPT _________________.

    • A.

      Exposure to air

    • B.

      The presence of hot, watery fluids

    • C.

      Both a and b

    • D.

      Heat and pressure

    Correct Answer
    C. Both a and b
    Explanation
    Metamorphic rocks are formed due to the process of heat and pressure acting on existing rocks, causing them to change in composition and texture. Exposure to air and the presence of hot, watery fluids can also contribute to the formation of metamorphic rocks, as they can introduce additional chemical reactions and alter the rock's structure. Therefore, the correct answer is "both a and b" because all of the given conditions can cause metamorphic rocks to form.

    Which two processes contributed most to the accumulation of soil in this river valley?

    • A.

      pressure and uplift

    • B.

      Earthquakes and faulting

    • C.

      Erosion and deposition

    • D.

      Percolation and evaporation

    Correct Answer
    C. Erosion and deposition
    Explanation
    Erosion and deposition are the two processes that contributed most to the accumulation of soil in this river valley. Erosion refers to the wearing away of soil and rock by the force of water, wind, or ice, while deposition is the process of depositing or laying down eroded materials in a new location. In the context of a river valley, the flowing water of the river erodes the surrounding soil and rocks, carrying the eroded materials downstream. As the water slows down or enters a body of water, it deposits the sediments it was carrying, leading to the accumulation of soil in the river valley.

    • A.

      Destroy matter

    • B.

      Create matter

    • C.

      Always create and destroy matter

    • D.

      Never create or destroy matter

    Correct Answer
    D. Never create or destroy matter
    Explanation
    The correct answer is "never create or destroy matter". The law of conservation of matter states that matter cannot be created or destroyed, only transformed or rearranged. In the context of the rock cycle, this means that the different processes involved, such as weathering, erosion, and deposition, do not result in the creation or destruction of matter. Instead, matter is continuously recycled and transformed from one form to another.

      Erosion

    • B.

      Uplift

    • C.

      Weathering

    • D.

      Deposition

    Correct Answer
    A. Erosion
    Explanation
    Erosion is the correct answer because it refers to the process responsible for breaking down rocks. Erosion involves the movement of rocks, sediments, and soil from one location to another through the action of wind, water, ice, or gravity. It can wear away rocks and reshape the Earth's surface over time. Weathering, on the other hand, refers to the breakdown of rocks into smaller pieces without any movement, while uplift and deposition are not directly related to the breaking down of rocks.
