Quiz Preview

  • 2. 

    Which type of rocks form due to extreme pressure or heat?

    • Igneous Rocks

    • Sedimentary Rocks

    • Metamorphic Rocks

    • Minerals

    Correct Answer
    A. Metamorphic Rocks
    Explanation
    Metamorphic rocks form due to extreme pressure or heat. This process causes the existing rocks to undergo a transformation, resulting in the formation of new rocks with different mineral composition and texture. The intense heat and pressure cause the minerals within the rocks to recrystallize and rearrange, leading to the formation of metamorphic rocks. Examples of metamorphic rocks include marble, slate, and gneiss.

    A scientist that studies the earth is called a

    Correct Answer
    geologist
    Geologist
    Explanation
    A scientist that studies the earth is called a geologist. Geologists study the composition, structure, and processes of the Earth, including its rocks, minerals, and landforms. They analyze geological data to understand the history and formation of the Earth, as well as to predict natural hazards such as earthquakes and volcanic eruptions. Geologists also play a crucial role in the exploration and extraction of natural resources like oil, gas, and minerals.

    Scientists group rocks into three types (igneous, sedimentary, and metamorphic) by theage of rocks.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Scientists group rocks into three types (igneous, sedimentary, and metamorphic) based on their origin and formation processes, not by the age of rocks. Age is a separate aspect that can be determined through various dating methods, but it does not determine the classification of rocks into these three types. Therefore, the statement is false.

    The changing and evolution of rocks from one type of rock to another that takesplace over time.

    Correct Answer
    rock cycle
    The Rock Cycle
    Explanation
    The rock cycle refers to the continuous process of transformation and evolution of rocks from one type to another over time. It involves various geological processes such as weathering, erosion, deposition, compaction, and crystallization. These processes occur over millions of years and are driven by the Earth's internal heat and external forces like water, wind, and ice. The rock cycle is a fundamental concept in geology and helps explain the formation of different types of rocks, including igneous, sedimentary, and metamorphic rocks.

    Select the answer that best defines sedimentary rocks. - ProProfs

    Select the answer that best defines sedimentary rocks.

    • The changing and evolution of rocks from one type of rock to another that takes place over time.

    • A type of rock that forms at Earth's surface. This rock may form from material that has been squeezed together or it may form from the material that is left after the evaporation of water.

    Correct Answer
    A. The changing and evolution of rocks from one type of rock to another that takes place over time.
    Explanation
    Sedimentary rocks are formed through the process of sedimentation, which involves the deposition and accumulation of sediment over time. This sediment can be derived from various sources such as weathering and erosion of existing rocks, or from the remains of plants and animals. As layers of sediment build up, they become compacted and cemented together, forming sedimentary rocks. This process of changing and evolving from one type of rock to another is known as the rock cycle, which occurs over long periods of time.

    The process in which rocks are broken down into smaller pieces by ice water thewind changes in temperature plants animals or by chemicals.

    Correct Answer
    erosion
    Explanation
    Erosion is the correct answer because it refers to the process by which rocks are broken down into smaller pieces. This can occur through various agents such as ice, water, wind, changes in temperature, plants, animals, or chemicals. Erosion is a natural process that wears away and transports the fragmented rock material, shaping the Earth's surface over time.
