  • 5. 

    The convection current is caused by ....

    • A.

      The heat releases by inner core

    • B.

      The heat produces by outer core

    • C.

      The liquid magma in the mantle

    • D.

      The movement of lithosphere

    Correct Answer
    A. The heat releases by inner core
    Explanation
    The convection current is caused by the heat released by the inner core. As the inner core is extremely hot, it heats up the surrounding material in the mantle. This causes the material to become less dense and rise towards the surface. As it reaches the surface, it cools down and becomes denser, causing it to sink back towards the core. This continuous cycle of rising and sinking material creates convection currents, which play a crucial role in driving the movement of tectonic plates on the Earth's surface.

  • 6. 

    This movement will caused ....

    • A.

      The magma to boil

    • B.

      The magma to melt

    • C.

      The lithosphere to move

    • D.

      The core become hot

    Correct Answer
    C. The lithosphere to move
    Explanation
    When the movement occurs, it causes the lithosphere, which is the rigid outer layer of the Earth, to move. This movement can be in the form of tectonic plate shifting, such as during an earthquake or volcanic activity. The lithosphere is divided into several large and small plates that float on the semi-fluid asthenosphere beneath it. When these plates move, they can collide, separate, or slide past each other, leading to various geological phenomena like mountain formation, the creation of oceanic trenches, or the eruption of volcanoes. Therefore, the given movement will cause the lithosphere to move.

    On which layer we could live?

    • A.

      Continental crust

    • B.

      Oceanic Crust

    • C.

      Upper mantle

    Correct Answer
    A. Continental crust
    Explanation
    We could live on the continental crust because it is the outermost layer of the Earth's surface and is where land masses, such as continents, are located. The continental crust is thicker and less dense compared to the oceanic crust, making it more suitable for human habitation. It is also where most of the Earth's landforms, such as mountains and valleys, are found.

    The thinner but denser crust which make up the deep ocean floor is ....

    • A.

      Continental crust

    • B.

      Oceanic crust

    • C.

      Upper mantle

    Correct Answer
    B. Oceanic crust
    Explanation
    The thinner but denser crust that makes up the deep ocean floor is called the oceanic crust. Unlike the continental crust, which is thicker and less dense, the oceanic crust is composed mainly of basaltic rocks. It is formed at mid-ocean ridges through volcanic activity and is constantly being created and destroyed through the process of seafloor spreading. The oceanic crust is also characterized by its higher density compared to the continental crust, which allows it to sink beneath the less dense continental crust in certain areas, forming subduction zones.

    Rate this question:

  • 9. 

    Continental crust is made up of granite rock which contain of Silica and Aluminium.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that continental crust is indeed made up of granite rock, which is composed of high amounts of silica and aluminum. Granite is a common type of rock found in the Earth's continental crust, and its composition includes a high percentage of silica and aluminum minerals. Therefore, the statement that continental crust is made up of granite rock containing silica and aluminum is true.

  • 10. 

    Oceanic crust is made up of basalt rock which contain Silica and Aluminium.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because oceanic crust is primarily made up of basalt rock, which contains iron and magnesium, not silica and aluminum. Silica and aluminum are more commonly found in continental crust.
