Earth Science Quiz: 8thh Grade Trivia Questions! - Quiz

The Earth's crust is unstable, especially at the edges of tectonic plates. You are expected to know how these plate boundaries are distributed around the world and the key features of each type of boundary, including the landforms they produce.


Questions and Answers
  • 1. 

    Which of the following statements is NOT correct?

    • A. 

      Tourism in fold mountains occurs all year round

    • B. 

      Volcanic soils are often very fertile

    • C. 

      Road and rail communications in fold mountains can be difficult

    • D. 

      Tourists are not allowed to visit volcanoes

    Correct Answer
    D. Tourists are not allowed to visit volcanoes
    Explanation
    The given statement "Tourists are not allowed to visit volcanoes" is not correct. Tourists are often allowed to visit volcanoes, either through guided tours or by hiking to certain accessible areas. Volcanoes are popular tourist attractions in many countries, offering opportunities for hiking, sightseeing, and even witnessing volcanic eruptions from a safe distance. However, it is important to note that access to active volcanoes may be restricted during periods of increased volcanic activity for safety reasons.

    Iceland is right on the constructive plate boundary between the Eurasian plate and the North American plate. Which of the following statements is correct?

    • A. 

      Many Icelanders are killed each year by volcanic eruptions

    • B. 

      Iceland can use geothermal energy to generate electricity

    • C. 

      Iceland is an uninhabited island because of the volcanoes

    • D. 

      It is not possible to farm on Iceland

    Correct Answer
    B. Iceland can use geothermal energy to generate electricity
    Explanation
    Iceland can use geothermal energy to generate electricity because it is located on the constructive plate boundary between the Eurasian plate and the North American plate. This geological activity results in a high concentration of volcanoes and geothermal activity in Iceland. Geothermal energy is harnessed by tapping into the heat generated by volcanic activity, allowing Iceland to generate a significant amount of its electricity from this renewable energy source.

    Which of the following is NOT a direct human use of fold mountains?

    • A. 

      Winter sports

    • B. 

      Agriculture

    • C. 

      Mobile telephone manufacture

    • D. 

      Electricity production

    Correct Answer
    C. Mobile telephone manufacture
    Explanation
    Fold mountains are formed by the collision of tectonic plates, resulting in the uplift of the Earth's crust. They are characterized by steep slopes and rugged terrain, making them unsuitable for mobile telephone manufacture. This industry requires flat and accessible land for the construction of manufacturing facilities and infrastructure. Therefore, mobile telephone manufacture is not a direct human use of fold mountains.

  • 4. 

    Which of the following methods of generating electricity is MOST likely to be developed in a mountainous area?

    • A. 

      Biogas

    • B. 

      Hydroelectric

    • C. 

      Nuclear

    • D. 

      Geothermal

    Correct Answer
    B. Hydroelectric
    Explanation
    Hydroelectric power is the most likely method to be developed in a mountainous area because it requires a large amount of flowing water, which can be easily obtained from rivers and streams that are abundant in mountainous regions. The elevation difference in the mountainous terrain allows for the construction of dams and reservoirs, which can store water and generate electricity through the force of falling water. Additionally, the steep slopes and natural gradient provide a favorable condition for the installation of turbines, maximizing the efficiency of hydroelectric power generation.

  • 5. 

    In fold mountains, roads usually follow the line of which of the following features?

    • A. 

      Pyramidal peaks

    • B. 

      Aretes

    • C. 

      Valleys

    • D. 

      Scree slopes

    Correct Answer
    C. Valleys
    Explanation
    In fold mountains, roads usually follow the line of valleys. Valleys are low-lying areas between mountains or hills, formed through erosion by rivers or glaciers. They provide a natural path of least resistance for roads to be built, as they are often flat and relatively easy to traverse compared to the steep slopes and rugged terrain of pyramidal peaks, aretes, and scree slopes. Following the line of valleys also allows for easier access to different areas and helps to minimize the impact on the surrounding environment during road construction.

    Why do people live near to active volcanoes?

    • A. 

      The soils can be very fertile

    • B. 

      The heat from the volcano creates a warm climate

    • C. 

      To save money on heating bills

    • D. 

      Houses near volcanoes are all a lot cheaper than other houses

    Correct Answer
    A. The soils can be very fertile
    Explanation
    People may choose to live near active volcanoes because the soils in these areas can be very fertile. Volcanic eruptions can release minerals and nutrients into the soil, making it highly productive for agriculture. This can provide a significant advantage for farmers and increase the chances of successful crop growth. Additionally, the volcanic activity can also create a warm climate, which can be appealing to some people. However, it is important to note that living near active volcanoes also comes with significant risks and potential dangers, such as volcanic eruptions and the release of toxic gases.

    The management of coniferous forests is an important use of fold mountains. Which of the following is NOT a use of these forests?

    • A. 

      Generating electricity on a large scale

    • B. 

      Fuel for heating homes

    • C. 

      Providing timber for building

    • D. 

      Providing an area for leisure activities

    Correct Answer
    A. Generating electricity on a large scale
    Explanation
    Coniferous forests are not used for generating electricity on a large scale. While they are used for fuel, timber, and leisure activities, generating electricity is not one of their primary uses. Coniferous forests are typically not dense enough to provide the necessary biomass for large-scale electricity generation. Additionally, other sources such as fossil fuels, hydroelectric power, and renewable energy sources are more commonly used for generating electricity.

    The three types of plate boundary are:

    • A. 

      Destructive, constructive and conservative

    • B. 

      Sideways, upwards and downwards

    • C. 

      Always passing each other on the left

    • D. 

      Locked in place

    Correct Answer
    A. Destructive, constructive and conservative
    Explanation
    The correct answer is destructive, constructive, and conservative. These are the three types of plate boundaries. Destructive boundaries occur when two plates collide, causing one plate to be forced beneath the other, leading to the formation of trenches and volcanic activity. Constructive boundaries occur when two plates move apart, resulting in the creation of new crust through volcanic activity and the formation of mid-ocean ridges. Conservative boundaries occur when two plates slide past each other horizontally, causing earthquakes but no creation or destruction of crust.

    On which slopes of fold mountains in the SOUTHERN hemisphere would agriculture be most likely to take place?

    • A. 

      East

    • B. 

      South

    • C. 

      West

    • D. 

      North

    Correct Answer
    D. North
    Explanation
    Agriculture would be most likely to take place on the northern slopes of fold mountains in the Southern hemisphere because these slopes receive more sunlight and have a warmer climate, which is favorable for crop growth. The northern slopes also tend to have better soil conditions and more access to water sources, making them more suitable for agriculture compared to the other slopes.

    Which of the following features is created at a destructive plate boundary?

    • A. 

      A crater

    • B. 

      Fold mountains

    • C. 

      Pillow lava

    • D. 

      A rift valley

    Correct Answer
    B. Fold mountains
    Explanation
    Fold mountains are created at destructive plate boundaries where two tectonic plates collide, causing compression and the crust to buckle and fold. As the plates converge, one plate is forced beneath the other in a process called subduction. The intense pressure and compression result in the formation of large, linear mountain ranges known as fold mountains. These mountains are characterized by folded and uplifted layers of rock, with steep slopes and rugged terrain. Examples of fold mountains include the Himalayas, the Andes, and the Alps.
