About This Quiz


The earth's structure is separated into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has its unique make-up and can impact life on the earth's surface. For this quiz, you will have to understand how many main layers the earth's internal structure is made of and what the earth's outer layer is known as. Don't just stay on the surface dig deep to learn from this quiz.

  • 2. 

    How many main layers is the internal structure of the Earth made of?

    • One

    • Two

    • Three

    Correct Answer
    A. Three
    Explanation
    The internal structure of the Earth is made up of three main layers: the crust, the mantle, and the core. The crust is the outermost layer, followed by the mantle, and then the core. These layers differ in composition, temperature, and physical properties. The crust is the thinnest and coolest layer, while the core is the hottest and densest. Understanding the Earth's internal structure is crucial for studying its geological processes and phenomena.

    What is the outer layer of the Earth known as ______________

    Correct Answer
    crust
    Explanation
    The outer layer of the Earth is known as the crust. The crust is the thinnest layer of the Earth and is made up of solid rock. It is divided into two types: the continental crust, which is thicker and less dense, and the oceanic crust, which is thinner and more dense. The crust is where all landforms, such as mountains, valleys, and plains, are located. It is also where the Earth's tectonic plates are found, which are responsible for earthquakes and volcanic activity.

    Rate this question:

  • 4. 

    The core is the most dense , and it is made of primarily __________ and __________.

    • Iron, nickel

    • Water, salad oil

    • Basalt, granite

    Correct Answer
    A. Iron, nickel
    Explanation
    The core of the Earth is the most dense part, and it is primarily composed of iron and nickel. Iron and nickel are elements that have high densities, which explains why the core is the most dense part of the Earth.

  • 5. 

    The layer between the outer layer and the innermost layer is known as ____________.

    Correct Answer
    mantle
    Explanation
    The layer between the outer layer and the innermost layer is known as the mantle. The mantle is a region of the Earth's interior that lies between the crust and the core. It is primarily composed of solid rock, but also contains pockets of molten rock called magma. The mantle plays a crucial role in the movement of tectonic plates and the formation of volcanic activity.

  • 6. 

    The layer in the center of the Earth is known as _______________ .

    Correct Answer
    core , Core
    Explanation
    The layer in the centre of the Earth is known as the core. The core is the innermost part of the Earth, consisting of two layers: the outer core and the inner core. The outer core is made up of liquid iron and nickel, while the inner core is solid. The core plays a crucial role in generating Earth's magnetic field and is responsible for the movement of tectonic plates.

    Rate this question:

  • 7. 

    Among the three layers of the internal structure of the Earth which is the densest layer?

    • Crust

    • Mantle

    • Core

    Correct Answer
    A. Core
    Explanation
    The core is the densest layer among the three layers of the internal structure of the Earth. It is composed mainly of iron and nickel, which are both heavy elements. The core is divided into two parts: the outer core, which is liquid, and the inner core, which is solid. The immense pressure at the center of the Earth causes these materials to be compressed and results in the high density of the core.

  • 8. 

    When the internal layers of the Earth hardened it caused the outer most layer, that is the  __[1]___________ to break into a number of __[2]__________.

    Correct Answer
    crust, plates
    Explanation
    The correct answer is "crust, plates." When the internal layers of the Earth hardened, it caused the outermost layer, known as the crust, to break into a number of plates. These plates are constantly moving and interacting with each other, resulting in various geological phenomena such as earthquakes, volcanic activity, and the formation of mountains.

    Rate this question:

  • 9. 

    How far do the plates move?

    • It is compared to the growth of one's fingernails.

    • It is about 1 cm per year

    • It is about 10 cm per year

    • It is about 10 km per year

    Correct Answer
    A. It is compared to the growth of one's fingernails.
    Explanation
    The plates move at a rate similar to the growth of one's fingernails. This means that the movement of the plates is very slow, approximately 1 cm per year.
