    Which type of rock is formed when molten magma or lava solidifies?

    • Igneous

    • Metamorphic

    • Sedimentary

    Correct Answer
    A. Igneous
    Explanation
    When molten magma or lava cools and solidifies, it forms igneous rock. Igneous rocks are formed from the cooling and solidification of molten material. This process can occur either beneath the Earth's surface (resulting in intrusive igneous rocks) or on the surface (resulting in extrusive igneous rocks). Examples of igneous rocks include granite, basalt, and obsidian.

    What is an igneous or sedimentary rock that has been changed by extreme pressure and heat?

    • Limestone

    • Conglomerate

    • Granite

    • Metamorphic

    Correct Answer
    A. Metamorphic
    Explanation
    Metamorphic rocks are formed when existing rocks, such as igneous or sedimentary rocks, undergo extreme pressure and heat, causing them to change in composition and texture. This process, known as metamorphism, can occur deep within the Earth's crust due to tectonic forces or contact with magma. Limestone, conglomerate, and granite are all examples of sedimentary or igneous rocks that can be transformed into metamorphic rocks through this process. Therefore, the correct answer is metamorphic.

    Sediments that have been pressed together form which rock?

    • Limestone

    • Marble

    • Sedimentary

    • Pumice

    Correct Answer
    A. Sedimentary
    Explanation
    Sedimentary rocks are formed when sediments, such as sand, silt, or clay, are compacted and cemented together over time. This process occurs under pressure, causing the sediments to become solid and form sedimentary rocks. Limestone and marble are examples of sedimentary rocks that are formed from the compaction of marine sediments and the recrystallization of limestone, respectively. Therefore, the correct answer is sedimentary.

    Which rock withstands weathering well and is often used for statues?

    • Marble

    • Slate

    • Obsidian

    • Shale

    Correct Answer
    A. Marble
    Explanation
    Marble is a rock that withstands weathering well and is often used for statues because of its durability and resistance to erosion. It is composed mainly of calcite, which is a relatively hard mineral that can withstand the effects of weathering, such as wind, rain, and temperature changes. Additionally, marble has a smooth and polished appearance, making it a popular choice for sculpting and creating statues.

    What is a well-known igneous rock that contains quartz, feldspar, and mica?

    • Obsidian

    • Pumice

    • Basalt

    • Granite

    Correct Answer
    A. Granite
    Explanation
    Granite is a well-known igneous rock that contains quartz, feldspar, and mica. It is a coarse-grained rock that is commonly used in construction and as a decorative stone. Granite forms when molten magma cools and solidifies deep within the Earth's crust. Its composition of quartz, feldspar, and mica gives it a unique combination of hardness, durability, and aesthetic appeal.

    Which rough, crumbly rock is sometimes used to make glass?

    • Limestone

    • Sandstone

    • Slate

    • Shale

    Correct Answer
    A. Sandstone
    Explanation
    Sandstone is a rough, crumbly rock that is sometimes used to make glass. Sandstone is composed mainly of sand-sized grains of mineral, rock, or organic material. It is a sedimentary rock formed from the consolidation and compaction of sand. Sandstone is often used in the glass industry because it contains a high percentage of silica, which is the main component of glass. Silica is melted and molded into glass products, making sandstone a suitable material for glass production.

    What is the weather-resistant, waterproof rock formed by metamorphosis of shale?

    • Basalt

    • Chalk

    • Slate

    • Marble

    Correct Answer
    A. Slate
    Explanation
    Slate is a weather-resistant and waterproof rock that is formed through the metamorphosis of shale. Shale is a sedimentary rock composed of compacted mud and clay particles. Under intense heat and pressure, shale undergoes metamorphism and transforms into slate. Slate is known for its fine-grained texture, durability, and ability to withstand various weather conditions, making it a suitable choice for roofing, flooring, and other outdoor applications.

    What is another name for rock salt?

    • Basalt

    • Halite

    • Gypsum

    • Limestone

    Correct Answer
    A. Halite
    Explanation
    Halite is another name for rock salt. Rock salt is a mineral form of sodium chloride, commonly known as table salt. It is called halite because it is primarily composed of the mineral halite. It is often found in sedimentary rocks and is commonly used as a seasoning and de-icing agent. Basalt, gypsum, and limestone are different types of rocks and not alternative names for rock salt.

    Which rock is made from pebbles cemented together?

    • Sandstone

    • Limestone

    • Gypsum

    • Conglomerate

    Correct Answer
    A. Conglomerate
    Explanation
    Conglomerate is the correct answer because it is a type of sedimentary rock formed from the consolidation and cementation of pebbles. The pebbles are typically rounded and vary in size, and they become cemented together over time to create a solid rock. This process occurs in environments such as riverbeds or beaches where the pebbles are transported and deposited, and then the cementation process takes place. Sandstone is made from sand grains, limestone is composed of calcium carbonate, and gypsum is a mineral composed of calcium sulfate, so they are not the correct answers.
