Questions and Answers
  • 1. 

    What name is given to 23.5 degrees north latitude?

    • A.

      Tropic Of Capricorn

    • B.

      International Dateline

    • C.

      Tropic Of Cancer

    • D.

      Prime Meridian

    Correct Answer
    C. Tropic Of Cancer
    Explanation
    The Tropic of Cancer is the name given to 23.5 degrees north latitude. This imaginary line marks the northernmost point where the Sun appears directly overhead at noon on the summer solstice. It is an important line of latitude as it divides the Earth into the Northern Hemisphere and the Southern Hemisphere. The Tropic of Cancer passes through countries such as Mexico, Egypt, India, and China.

    When a meander is cut off, what is formed?

    • A.

      Kettle

    • B.

      Borrow Pit

    • C.

      Tarn

    • D.

      Oxbow Lake

    Correct Answer
    D. Oxbow Lake
    Explanation
    When a meander is cut off, the river creates a new channel, leaving behind a U-shaped lake called an oxbow lake. This occurs when the river erodes the narrow strip of land between two bends in the meander, causing the river to take a shorter path. As a result, the abandoned meander loop becomes isolated from the main channel, forming the oxbow lake. Over time, sedimentation and vegetation may fill in the lake, transforming it into a marsh or wetland.

    What is another name for green beryl?

    • A.

      Peridot

    • B.

      Emerald

    • C.

      Malachite

    • D.

      Quartz

    Correct Answer
    B. Emerald
    Explanation
    Emerald is another name for green beryl. Beryl is a mineral that comes in various colors, and when it is green, it is commonly known as emerald. Peridot is a separate gemstone that has a distinct green color. Malachite is a different mineral that is also green but is not a type of beryl. Quartz is a clear or white mineral and is not associated with the color green. Therefore, the correct answer for another name for green beryl is emerald.

    The Appalachian Mountains are best described as what type of mountains?

    • A.

      Fault Block

    • B.

      Horst

    • C.

      Folded

    • D.

      Graben

    Correct Answer
    C. Folded
    Explanation
    The Appalachian Mountains are best described as folded mountains. This is because they were formed through a process of folding and faulting, where layers of rock were pushed together and folded over time. This resulted in the creation of long, linear ridges and valleys characteristic of folded mountains. The Appalachian Mountains stretch across the eastern part of North America, running from Canada to Alabama. They are known for their diverse ecosystems and rich natural resources.

  • 5. 

    Which mineral is not likely to be a replacement mineral in fossils?

    • A.

      Quartz

    • B.

      Pyrite

    • C.

      Gold

    • D.

      Chalcopyrite

    Correct Answer
    C. Gold
    Explanation
    Gold is not likely to be a replacement mineral in fossils because it is a noble metal that is highly resistant to corrosion and oxidation. Replacement minerals typically occur when the original minerals in the fossil are dissolved and replaced by other minerals through a process called diagenesis. However, gold is not easily dissolved or replaced by other minerals, making it unlikely to be a replacement mineral in fossils.

  • 6. 

    What must happen for a tree to become a fossil?

    • A.

      Must Be Exposed To Air

    • B.

      Must Decompose First

    • C.

      Quick Burial

    • D.

      Falling Into A River

    Correct Answer
    C. Quick Burial
    Explanation
    For a tree to become a fossil, it must undergo quick burial. Quick burial prevents the tree from decomposing and being exposed to air, which are essential factors for fossilization. When a tree is rapidly covered by sediment or soil, it is protected from decay and the elements. Over time, the organic materials in the tree are replaced by minerals, resulting in the formation of a fossil. Therefore, quick burial is necessary for the preservation and fossilization of a tree.

    What is the name given to a fossil that best defines a rock layer's age?

    • A.

      Preface Fossil

    • B.

      Content Fossil

    • C.

      Index Fossil

    • D.

      Annex Fossil

    Correct Answer
    C. Index Fossil
    Explanation
    Index fossils are used to define the age of rock layers because they are fossils of organisms that lived for a relatively short period of time but were widespread geographically. These fossils are useful because they can be found in multiple rock layers and can be used to correlate and date different rock formations. By studying the index fossils, scientists can determine the relative age of the rock layers and establish a timeline of Earth's history.

  • 8. 

    Which one of these is most alkali?

    • A.

      Mine Waters

    • B.

      Los Angeles Smog

    • C.

      Peat Water

    • D.

      Limestone Areas

    Correct Answer
    D. Limestone Areas
    Explanation
    Limestone areas are the most alkali because limestone is a sedimentary rock primarily composed of calcium carbonate, which is alkaline in nature. When limestone is exposed to water or moisture, it undergoes a process called carbonation, where the calcium carbonate reacts with carbon dioxide in the air to form calcium bicarbonate. This reaction increases the alkalinity of the water in limestone areas, making them more alkali compared to the other options listed.

    What breaks when its height is 3/4 of its depth?

    • A.

      Iceberg

    • B.

      Pillar

    • C.

      Wave

    • D.

      Mountain

    Correct Answer
    C. Wave
    Explanation
    A wave breaks when its height is 3/4 of its depth. This is because as a wave travels through the water, the energy of the wave causes the water particles to move in a circular motion. When the height of the wave becomes too large compared to its depth, the circular motion of the water particles becomes unstable and the wave breaks, causing it to crash and dissipate.

    Which type of irrigation is most commonly used throughout the world?

    • A.

      Subirrigation

    • B.

      Rolling Sprinkler

    • C.

      Furrow

    • D.

      Sprinkler

    Correct Answer
    C. Furrow
    Explanation
    Furrow irrigation is the most commonly used type of irrigation worldwide. This method involves creating small channels or furrows along the field and allowing water to flow through them, directly to the plant roots. Furrow irrigation is popular because it is relatively simple and inexpensive to implement, making it accessible to farmers in various regions. Additionally, it allows for efficient water distribution and can be adapted to different soil types and crop varieties.

    What must fossilize in order to form a coprolite?

    • A.

      Stomach Stones

    • B.

      Fur Balls

    • C.

      Scales

    • D.

      Feces

    Correct Answer
    D. Feces
    Explanation
    In order to form a coprolite, which is a fossilized piece of feces, the feces must undergo a process of mineralization. This occurs when the organic material in the feces is replaced by minerals, such as calcium carbonate or silica, over a long period of time. As the minerals gradually replace the organic matter, the feces hardens and becomes preserved as a coprolite. Therefore, the correct answer is feces.

    What type of topography describes caves, caverns, and sinkholes?

    • A.

      Karst

    • B.

      Kiskis

    • C.

      Boulder

    • D.

      Wurst

    Correct Answer
    A. Karst
    Explanation
    Karst is the correct answer because it is a type of topography that is characterized by the presence of caves, caverns, and sinkholes. Karst topography is formed by the dissolution of soluble rocks such as limestone, dolomite, and gypsum, which creates underground drainage systems and the formation of various landforms like caves and sinkholes. This type of topography is commonly found in areas with abundant rainfall and soluble rock formations.

    Most minerals may be identified using the following methods except which?

    • A.

      Hardness

    • B.

      Smell

    • C.

      Luster

    • D.

      Streak

    Correct Answer
    B. Smell
    Explanation
    The given question asks for the method that cannot be used to identify most minerals. Hardness, luster, and streak are commonly used methods to identify minerals. Hardness refers to the resistance of a mineral to scratching, luster refers to the appearance of the mineral's surface, and streak refers to the color of the powdered form of the mineral. However, smell is not a reliable method for identifying minerals as most minerals do not have a distinct smell.
