    In which type of rock are fossils generally found?

    • A.

      Metamorphic

    • B.

      Sedimentary

    • C.

      Igneous

    • D.

      Volcanic

    Correct Answer
    B. Sedimentary
    Explanation
    Fossils are generally found in sedimentary rock. Sedimentary rock is formed from the accumulation and cementation of sediment, which often includes the remains of plants and animals. Over time, the layers of sediment compress and harden, preserving the fossils within the rock. This is why sedimentary rock is the most common type of rock where fossils are found.

    The map below shows some geologic features located near the west coast of the United States. The arrows on either side of the fault represent

    • A.

      The relative movement of air masses

    • B.

      Rock formations

    • C.

      The relative movement of tectonic plates

    • D.

      Volcanic eruptions

    Correct Answer
    C. The relative movement of tectonic plates
    Explanation
    The map shows geologic features, which suggests that the arrows on either side of the fault represent the relative movement of tectonic plates. Tectonic plates are massive pieces of the Earth's lithosphere that move and interact with each other. Faults are fractures in the Earth's crust where tectonic plates slide past each other. The arrows indicate the direction of this movement, which is a key characteristic of tectonic plate boundaries.

    Which information would probably be most helpful to someone trying to identify a mineral sample?  

    • A.

      Hardness and streak of the sample

    • B.

      Color and size of the sample

    • C.

      Location and mass of the sample

    • D.

      Shape and texture of the sample

    Correct Answer
    A. Hardness and streak of the sample
    Explanation
    To identify a mineral sample, knowing its hardness and streak would be the most helpful information. Hardness helps determine the resistance of a mineral to scratching, while streak refers to the color of the powdered mineral. These characteristics are often unique to specific minerals, allowing for their identification. The color and size of the sample can be misleading as many minerals can occur in different colors, and size does not provide enough information for identification. The location and mass of the sample are also not reliable indicators as minerals can be found in various locations and their mass does not provide specific identification clues. Shape and texture can be helpful, but they are less distinctive compared to hardness and streak.

    • A.

      Density

    • B.

      Mass

    • C.

      Hardness

    • D.

      Volume

    Correct Answer
    D. Volume
    Explanation
    When the rock is placed in the overflow container, the amount of water that comes out of the overflow spout can be collected in the graduated cylinder. By measuring the volume of water collected, the volume of the rock can be directly determined. The volume of an object is a physical property that represents the amount of space it occupies. Therefore, the correct answer is volume.

    Limestone is a sedimentary rock and marble is a metamorphic rock. Even though limestone and marble have the same chemical makeup, they are classified as different rocks because they

    • A.

      Formed at different times

    • B.

      Formed by different methods

    • C.

      Took different amounts of time to form

    • D.

      Were formed from different fossils

    Correct Answer
    B. Formed by different methods
    Explanation
    Limestone and marble are classified as different rocks because they formed by different methods. Limestone is formed through the accumulation of shells, coral, and other organic remains, while marble is formed through the metamorphosis of limestone under high heat and pressure. Although they have the same chemical makeup, the different formation processes result in distinct characteristics and properties, making them separate types of rocks.

    Most of Earth’s major earthquakes are caused by

    • A.

      Weathering of rock at Earth’s surface

    • B.

      Seasonal heating and cooling of Earth’s surface

    • C.

      Earth’s gravitational attraction to the Moon

    • D.

      Faulting of rock in Earth’s crust

    Correct Answer
    D. Faulting of rock in Earth’s crust
    Explanation
    Earthquakes are caused by the faulting of rock in Earth's crust. Faulting occurs when stress builds up along a fault line, causing the rocks on either side to move and release energy in the form of seismic waves. This movement can occur due to tectonic plate movement, volcanic activity, or other geological processes. Faulting is the most common cause of major earthquakes on Earth, as it is responsible for the majority of seismic activity along fault lines.

    The diagram below shows a method for determining a physical property of a mineral. The results are shown for two minerals, galena and calcite. Which property of the galena and calcite is indicated by the color of the powder each leaves on the ceramic tile?

    • A.

      Hardness

    • B.

      Reaction to an acid

    • C.

      Streak

    • D.

      Reaction to a solvent

    Correct Answer
    C. Streak
    Explanation
    The color of the powder left on the ceramic tile indicates the streak of the mineral. Streak refers to the color of the powdered form of a mineral when it is scraped across a surface. Different minerals have different colored streaks, which can be used as a diagnostic property to identify minerals. In this case, the colors of the powder left by galena and calcite on the ceramic tile can be used to determine their streak and differentiate between the two minerals.

    The diagram below shows two locations where fossils of Mesosaurus have been found. Mesosaurus was a freshwater reptile that existed on Earth about 250 million years ago. Which statement best explains why these freshwater Mesosaurus fossils are found today in some rock layers in both South America and Africa?

    • A.

      The continents were once connected as a single landmass.

    • B.

      Mesosaurus swam across the ocean between the continents.

    • C.

      The remains of Mesosaurus were carried across the ocean by predators.

    • D.

      Global warming has been raising the sea level in the Atlantic Ocean.

    Correct Answer
    A. The continents were once connected as a single landmass.
    Explanation
    The correct answer is that the continents were once connected as a single landmass. This is supported by the fact that Mesosaurus fossils are found in both South America and Africa, which are now separated by the Atlantic Ocean. The presence of the same freshwater reptile in both locations suggests that there was a land connection between the two continents in the past, allowing the reptiles to freely inhabit both areas. This explanation is consistent with the theory of continental drift, which states that the continents were once joined together in a supercontinent called Pangaea.

    Convection currents, which may be the driving force for the movement of lithospheric plates, are mostly found in Earth's

    • A.

      Crust

    • B.

      Outer core

    • C.

      Inner core

    • D.

      Plastic mantle

    Correct Answer
    D. Plastic mantle
    Explanation
    Convection currents are the circular movements of material caused by differences in temperature and density. In the context of the Earth's lithospheric plates, convection currents are responsible for the movement of these plates. The plastic mantle, also known as the asthenosphere, is a layer of the Earth's mantle that is semi-fluid and capable of flowing over long periods of time. It is in this plastic mantle layer that convection currents occur, as the heat from the Earth's core causes the material to rise, cool, and then sink back down, creating a continuous cycle of movement. Therefore, the plastic mantle is the most likely location for these convection currents to be found.

      Trilobites

    Correct Answer
    D. Trilobites
    Explanation
    Trilobites are considered the oldest fossil in the cross section shown. Trilobites are a group of extinct marine arthropods that lived over 500 million years ago. They are known for their distinctive segmented bodies and hard exoskeletons. Trilobite fossils have been found in abundance and provide valuable insights into the ancient marine ecosystems and the evolution of early life on Earth. Therefore, based on their age and presence in the cross section, trilobites are considered the oldest fossil in this context.
