Questions and Answers
  • 1. 

    Rocks are made of?

    • A.

      Ice

    • B.

      Metal

    • C.

      Coal

    • D.

      Minerals

    Correct Answer
    D. Minerals
    Explanation
    Rocks are made of minerals. Minerals are naturally occurring inorganic substances that make up the solid structure of rocks. Different types of rocks are composed of different minerals, such as quartz, feldspar, and mica. These minerals combine and form the various textures and colors seen in rocks. While ice, metal, and coal are substances that can be found in nature, they are not the primary components of rocks.

    I saw a landslide last week when it rained really heavily. The rocks tumbled down a hill and landed in a creek. This is an example of:

    • A.

      Rock'n Roll

    • B.

      Precipitation

    • C.

      Positation

    • D.

      Erosion

    Correct Answer
    D. Erosion
    Explanation
    erosion is when any solid material is moved by gravity. It contributes to lost soil, breaks down mountains, and begins the process of rock recycling.

    Mauna Kea is the biggest mountain in the world and is an inactive volcano. What type of rocks would you most likely find on Mauna Kea?

    • A.

      Metamorphic

    • B.

      Pyroclines

    • C.

      Sedimentary

    • D.

      Igneous

    Correct Answer
    D. Igneous
    Explanation
    Mauna Kea being an inactive volcano suggests that the rocks found on it would most likely be igneous. Igneous rocks are formed from the solidification of molten magma or lava, which is commonly associated with volcanic activity. Since Mauna Kea is an inactive volcano, it indicates that it has experienced volcanic eruptions in the past, resulting in the formation of igneous rocks. Therefore, it is reasonable to expect that igneous rocks would be the most common type of rocks found on Mauna Kea.

    • C.

      Sandstone

    • D.

      Metamorphic

    Correct Answer
    A. Sedimentary
    Explanation
    Sedimentary rocks are made up of small or big pieces of other rocks and things like mud clay, and sand.

    I found a cool looking mineral walking to acme the other day. I wanted to test how hard the mineral was. How could I do this?

    • A.

      Smash it with a hammer as hard as I can

    • B.

      Try and scrape a piece of glass with it

    • C.

      Heat it in the oven to 500 degrees

    • D.

      Put it in acid

    Correct Answer
    B. Try and scrape a piece of glass with it
    Explanation
    Hardness has nothing to do with how easy it breaks. A diamond can shatter. However, hardness does tell us how easily it can be scratched. A diamond will scratch ANY natural material on Earth, including steel, glass, and titanium.

    To make a metamorphic rock I need to add 2 things to any other type of rock. What are they?

    • A.

      Cold temperatures and time

    • B.

      Acid and Water

    • C.

      Heat and Pressure

    • D.

      Time and Weather

    Correct Answer
    C. Heat and Pressure
    Explanation
    Metamorphic rocks are formed by the application of heat and pressure to existing rocks, causing them to undergo physical and chemical changes. The heat comes from the Earth's internal heat sources or from the proximity to magma, while the pressure is exerted by the weight of overlying rocks or tectonic forces. These two factors, heat and pressure, act together over time to transform the mineral composition and texture of the original rock, resulting in the formation of metamorphic rocks.

    The picture below shows a rock with thin lines of parallel, flattened crystals. What type of rock is this?  

    • A.

      Metamorphic

    • B.

      Igneous

    • C.

      Pyroclastic

    • D.

      Sedimentary

    Correct Answer
    A. Metamorphic
    Explanation
    Think of metamorphic rocks as rocks that have been heated and squeezed over millions of years. This makes crystals line up, flatten out, and form lined patterns.

    Cooling magma forms what type of rock?

    • A.

      Igneous

    • B.

      Metamorphic

    • C.

      Sandy

    • D.

      Conglomerate

    Correct Answer
    A. Igneous
    Explanation
    Cooling magma forms igneous rock. Magma is molten rock that is found beneath the Earth's surface. When magma cools and solidifies, it forms igneous rock. This process can occur either slowly beneath the surface, resulting in intrusive igneous rock, or quickly on the surface, resulting in extrusive igneous rock. Igneous rocks can have a variety of textures and compositions depending on the cooling rate and mineral content of the magma. Examples of igneous rocks include granite, basalt, and pumice.

    Sediment is:

    • A.

      A type of cement

    • B.

      A word for scientific observations

    • C.

      A bunch of small pieces of rocks and other material

    • D.

      A type of water that is undrinkable

    Correct Answer
    C. A bunch of small pieces of rocks and other material
    Explanation
    Sediment refers to a collection of small pieces of rocks and other materials that settle at the bottom of a body of water. These materials can include sand, silt, clay, and organic matter. Over time, the layers of sediment can become compacted and cemented together, forming sedimentary rocks. Sediment plays a crucial role in various geological processes, such as the formation of landforms, the deposition of minerals, and the preservation of fossils.

    If a mineral has a metallic luster, it has what type of luster?

    • A.

      Metallic

    • B.

      Dull

    • C.

      Submetallic

    • D.

      Glassy

    Correct Answer
    A. Metallic
    Explanation
    A mineral with a metallic luster reflects light in a way that is similar to metals, giving it a shiny and reflective appearance. This type of luster is often associated with minerals that contain metallic elements such as gold, silver, or copper. Dull luster refers to a mineral that lacks shine and appears dull. Submetallic luster is a less intense version of metallic luster, with a slightly duller shine. Glassy luster describes a mineral that appears similar to glass, with a shiny and transparent appearance.

    Sedimentary rocks are usually made:

    • A.

      On top of volcanos

    • B.

      On land

    • C.

      Beneath the ocean and rivers

    • D.

      In space

    Correct Answer
    C. Beneath the ocean and rivers
    Explanation
    Sedimentary rocks are usually made beneath the ocean and rivers because these environments provide the necessary conditions for sedimentary rock formation. Over time, sediments such as sand, silt, and clay accumulate in these bodies of water, and as the weight of the overlying sediment increases, it compacts and hardens into solid rock. The constant movement of water helps in the deposition and compaction of sediments, leading to the formation of sedimentary rocks. This process takes place over millions of years, resulting in the formation of layers of sedimentary rocks beneath the ocean and rivers.

    Correct Answer
    D. Crystal
    Explanation
    The picture shows atoms arranged in a fixed pattern, which is a characteristic of a crystal. Crystals are solid materials made up of repeating patterns of atoms, ions, or molecules. This arrangement gives crystals their unique shape and properties.

    B. Hardness
    C. Reaction with acid
    D. Radioactivity
    E. Luster
    F. Density
    G. Flourescence
    H. Taste
    Explanation
    Properties of minerals include magnetism, hardness, reaction with acid, radioactivity, luster, density, fluorescence, and taste. These properties are used to identify and classify minerals. Magnetism refers to the ability of a mineral to attract or repel certain metals. Hardness refers to the resistance of a mineral to scratching or abrasion. Reaction with acid indicates whether a mineral will fizz or dissolve when exposed to acid. Radioactivity refers to the emission of radiation by certain minerals. Luster refers to the way light reflects off the surface of a mineral. Density refers to the mass per unit volume of a mineral. Fluorescence refers to the ability of a mineral to emit visible light when exposed to ultraviolet light. Taste refers to the taste of certain minerals when licked.
