About This Quiz

How well do you know about the rock cycle? Try this "Geology rock cycle quiz" and test yourself. The rocks that form on the earth's surface undergo many changes with time, and there are essentially three types of rocks. These changes in these rocks either happen due to weathering or erosion. Do you have a good idea of what these processes entail? Take up the quiz below and test your knowledge of the rock cycle. Wish you good luck!

  • 2. 

    When molten magma or lava solidifies, it forms...

    • Igneous

    • Metamorphic

    • Sedimentary

    • None of these

    Correct Answer
    A. Igneous
    Explanation
    When molten magma or lava cools and solidifies, it forms igneous rocks. Igneous rocks are formed through the process of crystallization, where the molten material cools and hardens, trapping minerals within it. This process typically occurs beneath the Earth's surface, but can also occur on the surface as lava cools rapidly. Igneous rocks are characterized by their interlocking crystal structure and can be further classified based on their texture and mineral composition. Examples of igneous rocks include granite, basalt, and obsidian.

    From which rock do sediments that have been pressed together form?

    • Limestone

    • Marble

    • Sedimentary

    • Pumice

    Correct Answer
    A. Sedimentary
    Explanation
    Sedimentary rocks are formed when loose sediments, such as sand, silt, and clay, are compacted and cemented together over time. This process occurs due to the weight of the overlying layers of sediment, which causes the sediments to become tightly packed and solidify into rock. Limestone and marble are both examples of sedimentary rocks that are formed from the compression of sediment. Pumice, on the other hand, is an igneous rock that forms from volcanic activity and does not involve the compaction of sediments.

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

    • Limestone

    • Conglomerate

    • Granite

    • Metamorphic

    Correct Answer
    A. Metamorphic
    Explanation
    Igneous and sedimentary rocks are not changed by extreme pressure and heat, but metamorphic rocks are. Limestone, conglomerate, and granite are all examples of sedimentary and igneous rocks, respectively.

    Rate this question:

  • 5. 

    Which rock withstands weathering (also often used for statues)?

    • Marble

    • Slate

    • Obsidian

    • Shale

    Correct Answer
    A. Marble
    Explanation
    Marble is a rock that is known for its durability and ability to withstand weathering. It is often used for statues because it can withstand exposure to the elements without deteriorating easily. Marble is a metamorphic rock that forms from limestone under intense heat and pressure. Its composition and structure make it resistant to weathering processes such as erosion and chemical weathering. Therefore, marble is the correct answer as it is a rock that can withstand weathering and is commonly used for statues.

    To make glasses, which crumbly and rough rock is sometimes used?

    • Limestone

    • Sandstone

    • Slate

    • Shale

    Correct Answer
    A. Sandstone
    Explanation
    Sandstone is sometimes used to make glasses because it is a crumbly and rough rock. Sandstone is composed of sand-sized grains of mineral, rock, or organic material, which gives it its characteristic texture. This texture makes sandstone suitable for grinding and shaping into glassware. Additionally, sandstone is relatively abundant and easily accessible, making it a practical choice for glass production.

    Tell the name of a well-known igneous rock that has 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. The presence of quartz gives granite its hardness and durability, while feldspar provides its characteristic color and mica adds a shimmering appearance. Granite is widely recognized for its strength, beauty, and versatility, making it a popular choice for countertops, flooring, and monuments.

    Weather-resistant and waterproof rock that is formed by the metamorphosis of shale is

    • Basalt

    • Chalk

    • Slate

    • Marble

    Correct Answer
    A. Slate
    Explanation
    Slate is a weather-resistant and waterproof rock that is formed by the metamorphosis of shale. Shale is a sedimentary rock composed of clay minerals, and when it undergoes metamorphism, it transforms into slate. Slate has a fine-grained texture and is known for its ability to split into thin, flat sheets. It is commonly used as a roofing material due to its durability and resistance to weathering and water absorption. Therefore, slate is the correct answer.

    If pebbles are cemented together, then which rock is made?

    • Sandstone

    • Limestone

    • Gypsum

    • Conglomerate

    Correct Answer
    A. Conglomerate
    Explanation
    When pebbles are cemented together, they form a rock called conglomerate. Conglomerate is a sedimentary rock composed of rounded pebbles, which are held together by a matrix of smaller particles or mineral cement. This cementation process occurs over time through pressure and the precipitation of minerals, resulting in a solid and durable rock formation. Therefore, conglomerate is the correct answer for this question.

    What is another name for rock salt?

    • Basalt

    • Halite

    • Gypsum

    • Limestone

    Correct Answer
    A. Halite
    Explanation
    Halite is another name for rock salt. It is a mineral form of sodium chloride and is commonly found in sedimentary rocks. Halite is often colorless or white, but can also be found in shades of blue, purple, or pink due to impurities. It is commonly used as a seasoning and for de-icing roads.
