About This Quiz

Earth is the only planet where humans can survive. But have you ever wondered how the earth formed? How many layers are there? Earth's structure is like a spherical shell which consists of crust, asthenosphere, mantle, a liquid outer core, and solid inner core. To know more about the mystery, take this quiz and dig out answers. Let's explore the layers of the earth and test your knowledge. All the best!

    Which layer can be worn down by erosion and weathering (weathering is when weather like rain and wind blow against rocks and break them up)

    • Crust

    • Mantle

    • Outer Core

    • Inner Core

    Correct Answer
    A. Crust
    Explanation
    The crust is the outermost layer of the Earth's surface and is composed of solid rocks. It is the layer that is directly exposed to the elements and is therefore susceptible to erosion and weathering. Erosion occurs when natural forces like wind, water, and ice wear away the surface of the crust, while weathering refers to the breakdown of rocks caused by exposure to weather conditions such as rain and wind. Therefore, the crust is the layer that can be worn down by erosion and weathering.

     The core is made up of what two elements?

    • Iron and nickel

    • Iron and oxygen

    • Nickel and silicon

    • Oxygen and silicon

    Correct Answer
    A. Iron and nickel
    Explanation
    The core of the Earth is composed of iron and nickel. This is supported by scientific evidence and geological studies. The iron-nickel core is believed to be responsible for generating the Earth's magnetic field. Iron and nickel are both dense and heavy elements, making them suitable for forming the solid inner core and the liquid outer core of the Earth.

    Which layer contains the highest mountains and the deepest oceans?

    • Crust

    • Mantle

    • Outer Core

    • Inner Core

    Correct Answer
    A. Crust
    Explanation
    The crust is the outermost layer of the Earth's surface and is composed of solid rock. It is where the highest mountains, such as the Himalayas, are found. Additionally, the deepest parts of the oceans, such as the Mariana Trench, are also located in the crust. Therefore, the crust contains both the highest mountains and the deepest oceans on Earth.

    Which layer has the coolest temperature?

    • Crust

    • Mantle

    • Outer Core

    • Inner Core

    Correct Answer
    A. Crust
    Explanation
    The crust is the outermost layer of the Earth, and it is the layer that is closest to the surface. It is composed of solid rock and has the coolest temperature compared to the other layers. The mantle, outer core, and inner core are all deeper layers within the Earth, and they have higher temperatures due to the intense heat and pressure found at those depths. Therefore, the crust has the coolest temperature among the given options.

    The inner core is.......

    • Liquid

    • Solid

    • Gas

    • None

    Correct Answer
    A. Solid
    Explanation
    The inner core is solid because it is composed mainly of iron and nickel, which are both dense and have high melting points. The immense pressure in the Earth's core keeps these materials in a solid state, despite the high temperatures. Additionally, seismic waves passing through the inner core have shown that it behaves like a solid, transmitting the waves at faster speeds than if it were liquid or gas. Therefore, the solid state of the inner core is supported by both its composition and its behavior.

     Large pieces of lithosphere that move around on the asthenosphere are called

    • Crust plates

    • Tectonic plates

    • Mantle pieces

    • Core plates

    Correct Answer
    A. Tectonic plates
    Explanation
    Tectonic plates are large pieces of lithosphere that move around on the asthenosphere. These plates are responsible for the movement and interaction of Earth's crust, leading to geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges. The term "crust plates" is not commonly used to describe these lithospheric plates, and "mantle pieces" and "core plates" are incorrect because they do not accurately describe the location or composition of these plates.

    Which layer contains most of the earth’s mass?

    • Crust

    • Mantle

    • Outer Core

    • Inner Core

    Correct Answer
    A. Mantle
    Explanation
    The mantle contains most of the earth's mass. The mantle is the layer between the crust and the outer core. It is composed of solid rock that is hot and semi-fluid. The mantle makes up about 84% of the Earth's volume and is responsible for the movement of tectonic plates. It is also where convection currents occur, causing the movement of molten rock and creating volcanic activity. Overall, the mantle plays a crucial role in the structure and dynamics of the Earth.

     The four layers that make up the earth’s composition is

    • Crust, Lithosphere, Mesosphere and Core

    • Lithosphere, Asthenosphere, Mantle and Core

    • Crust, Mantle, Outer Core and Inner Core

    • Mantle, Outer Core, Lithosphere and Crust

    Correct Answer
    A. Crust, Mantle, Outer Core and Inner Core
    Explanation
    The correct answer is Crust, Mantle, Outer Core, and Inner Core. This is because the Earth is composed of several layers, with the crust being the outermost layer. Beneath the crust is the mantle, which is a thick layer of rock. Below the mantle is the outer core, which is composed of liquid iron and nickel. Finally, at the center of the Earth is the inner core, which is a solid ball of iron and nickel. Therefore, the four layers that make up the Earth's composition are the crust, mantle, outer core, and inner core.

    When the Crust sinks down into the Mantle what happens to it?

    • It becomes a tectonic plate

    • It slowly floats up

    • It sinks to the inner core

    • It Melts

    Correct Answer
    A. It Melts
    Explanation
    When the crust sinks down into the mantle, the intense heat and pressure cause it to melt. This melting occurs because the mantle is made up of semi-fluid rock called magma. As the crust sinks deeper into the mantle, it is subjected to higher temperatures and pressures, causing it to gradually melt and become part of the molten magma in the mantle. This process is a key component of the Earth's dynamic system, as it contributes to the recycling of crustal material and the formation of new rocks.
