    What is a rock that forms when existing rock is changed by heat and pressure beneath Earth's surface called?

    • Mineral

    • Sedimentary Rock

    • Metamorphic Rock

    • Rock

    Correct Answer
    A. Metamorphic Rock
    Explanation
    A rock that forms when existing rock is changed by heat and pressure beneath Earth's surface is called a metamorphic rock. This process involves the transformation of the original rock's mineral composition and texture, resulting in a new type of rock with different physical and chemical properties. Examples of metamorphic rocks include marble, slate, and quartzite.

    What is a rock that forms when sand, particles of rock, bits of soil, and remins of once-living things are cemented called?

    • Fresh Water Rocks

    • Metamorphic Rock

    • Igneous Rock

    • Sedimentary Rock

    Correct Answer
    A. Sedimentary Rock
    Explanation
    A sedimentary rock is formed when loose particles such as sand, rock fragments, soil, and organic remains are compacted and cemented together over time. This process occurs in areas like riverbeds, lakes, and oceans where sediments accumulate and undergo pressure and chemical processes to form solid rock. Sedimentary rocks are characterized by their layered appearance and can contain fossils, making them valuable for understanding Earth's history. Freshwater rocks, metamorphic rocks, and igneous rocks are different types of rocks that form through distinct processes and do not involve the cementation of sediment particles.

    Which word describes how easily a mineral can be scratched?

    • Mineral

    • Sedimentary Rock

    • Rock Cycle

    • Hardness

    Correct Answer
    A. Hardness
    Explanation
    Hardness is the word that describes how easily a mineral can be scratched. It is a measure of the resistance of a mineral to being scratched or abrasion. Minerals with a higher hardness are able to scratch minerals with a lower hardness. The Mohs scale is commonly used to measure hardness, with diamond being the hardest mineral at the top of the scale.

    Which word describes the way a mineral shines?

    • Luster

    • Metallic Mineral

    • Streak

    • Cleavage

    Correct Answer
    A. Luster
    Explanation
    Luster is the term used to describe the way a mineral shines. It refers to the appearance of the mineral's surface when it reflects light. Some minerals may have a metallic luster, while others may have a glassy, pearly, or dull luster. The term "luster" helps in identifying and categorizing minerals based on their visual properties.

    What is a mineral's tendency to split along flat surfaces?

    • Hardness

    • Cleavage

    • Luster

    • Streak

    Correct Answer
    A. Cleavage
    Explanation
    Cleavage refers to a mineral's tendency to split along flat surfaces. It is a property that depends on the internal arrangement of atoms within the mineral's crystal structure. When a mineral has cleavage, it means that it can break along specific planes, resulting in smooth, flat surfaces. The number and orientation of these planes determine the quality and type of cleavage exhibited by the mineral. Cleavage is different from hardness, which measures a mineral's resistance to scratching, luster, which describes its appearance in reflected light, and streak, which refers to the color of a mineral's powder.

    What is a mineral that is shiny like a metal called?

    • Metallic Mineral

    • Non-metallic Mineral

    • Luster

    • Metamorphic Rock

    Correct Answer
    A. Metallic Mineral
    Explanation
    A mineral that is shiny like a metal is called a metallic mineral. Metallic minerals have a characteristic luster that resembles the shine of metals. These minerals are typically opaque and reflect light, giving them a metallic appearance. Some examples of metallic minerals include gold, silver, copper, and iron. These minerals are often valued for their aesthetic appeal and economic importance, as they are used in various industries such as jewelry making and construction.

    What is a nonliving solid that has a definite chemical makeup and is found in Earths outermost layer called?

    • Mineral

    • Metallic Mineral

    • Non Mineral

    • Igneous Rock

    Correct Answer
    A. Mineral
    Explanation
    A mineral is a nonliving solid that has a definite chemical makeup and is found in Earth's outermost layer. It is a naturally occurring substance that is formed through geological processes and has a specific crystalline structure. Minerals can be found in various forms such as rocks, ores, and gemstones. They are important for various industries and have a wide range of uses, including construction, manufacturing, and jewelry making.

    What is a mineral that is dull or glassy called?

    • Metallic Minerals

    • Non Metallic Minerals

    • Luster Minerals

    • Igneous Rock

    Correct Answer
    A. Non Metallic Minerals
    Explanation
    Non-metallic minerals are minerals that do not have the characteristic of being shiny or reflective like metallic minerals. Instead, they have a dull or glassy appearance. Examples of non-metallic minerals include quartz, feldspar, mica, and talc. These minerals are often used in industries such as construction, ceramics, and cosmetics.

    What is a solid material made up of one or more minerals called?

    • Sedimentary Rock

    • Rock

    • Metallic Rock

    • Metamorphic Rock

    Correct Answer
    A. Rock
    Explanation
    A solid material made up of one or more minerals is called a rock. Rocks are composed of minerals and can be classified into different types such as sedimentary, metamorphic, and igneous rocks based on their formation process. Sedimentary rocks are formed from the accumulation and compression of sediments, while metamorphic rocks are formed from the transformation of existing rocks due to heat and pressure. Metallic rock is not a recognized term in geology.

    What is a hypothesis?

    • The conclusion when you gather all of your results

    • An answer to a thought about science question

    • An educated guess

    • All of the above

    Correct Answer
    A. An educated guess
    Explanation
    A hypothesis is an educated guess in the context of scientific research. It is a proposed explanation or prediction based on prior knowledge and observations that can be tested through experimentation. It is not the conclusion of the study or the gathering of results, but rather the initial statement that guides the research process. Therefore, the correct answer is "An educated guess."
