About This Quiz

The earth's magnetic field refers to the force that extends from the internal part of the earth into the outer space. The strength of the geomagnetic field is as a result of the intense electric current from the earth's core. Are you in the know? Take this quiz if you do.

    What part of the earth is under the influence of the magnetic field ?  - ProProfs

    What part of the earth is under the influence of the magnetic field ? 

    • Biosphere 

    • Lithosphere 

    • Magnetosphere 

    • Hydrosphere 

    Correct Answer
    A. Magnetosphere 
    Explanation
    The magnetosphere is the part of the Earth that is under the influence of the magnetic field. It is the region of space around the Earth where the planet's magnetic field interacts with the solar wind, a stream of charged particles emitted by the Sun. The magnetosphere acts as a protective shield, deflecting most of the solar wind particles and preventing them from reaching the Earth's surface. It plays a crucial role in protecting our planet and its inhabitants from harmful radiation and other space weather effects.

    Which of these is most likely to repel?  - ProProfs

    Which of these is most likely to repel? 

    • Like poles 

    • North poles 

    • Unlike poles 

    • South poles 

    Correct Answer
    A. Like poles 
    Explanation
    Like poles are most likely to repel because they have the same magnetic polarity. According to the laws of magnetism, like poles repel each other, causing a force of repulsion. This is because the magnetic field lines from both poles are in the same direction and try to move away from each other. On the other hand, unlike poles attract each other because their magnetic field lines are in opposite directions and tend to come together. Therefore, the correct answer is like poles.

    Which of these is positive for an eastward deviation of the field relative to true north? - ProProfs

    Which of these is positive for an eastward deviation of the field relative to true north?

    • Magnetic declination 

    • Geodynamo 

    • Celestial pole 

    • Geographical declination 

    Correct Answer
    A. Magnetic declination 
    Explanation
    Magnetic declination refers to the angle between magnetic north and true north. An eastward deviation of the field relative to true north means that magnetic north is located to the east of true north. Therefore, magnetic declination is positive for an eastward deviation of the field relative to true north.

    What is the study of past magnetic field of the Earth called?  - ProProfs

    What is the study of past magnetic field of the Earth called? 

    • Paleomagnetism 

    • Quantal magnetism 

    • Magnetostratigraphy 

    • Spiral magnetism 

    Correct Answer
    A. Paleomagnetism 
    Explanation
    Paleomagnetism is the study of the Earth's past magnetic field. It involves analyzing the magnetic properties of rocks and sediments to determine the direction and intensity of the ancient magnetic field. By studying paleomagnetism, scientists can gain insights into the movement of tectonic plates, the history of the Earth's magnetic field, and even the past positions of continents. This field of study has been crucial in providing evidence for plate tectonics and has contributed to our understanding of Earth's geological history.

    How is the intensity of the earth's magnetic field measured?  - ProProfs

    How is the intensity of the earth's magnetic field measured? 

    • Gauss 

    • Tesla 

    • Newton 

    • Ampere 

    Correct Answer
    A. Gauss 
    Explanation
    The intensity of the earth's magnetic field is measured using the unit called Gauss. Gauss is a unit of magnetic field strength, named after the German mathematician and physicist Carl Friedrich Gauss. It is commonly used to measure the strength of magnetic fields, including the earth's magnetic field.

    What is the process by which escapes convection currents from the earth's core called?  - ProProfs

    What is the process by which escapes convection currents from the earth's core called? 

    • Microteslas

    • Geodynamo 

    • Paleomagnetism 

    • Magnetosphere 

    Correct Answer
    A. Geodynamo 
    Explanation
    The process by which escapes convection currents from the earth's core is called geodynamo. Geodynamo refers to the generation of a magnetic field by the motion of molten iron in the outer core of the Earth. The convection currents in the molten iron create electric currents, which in turn generate a magnetic field. This magnetic field is what protects the Earth from harmful solar radiation and creates the magnetosphere.

    What continent houses the northern, magnetic pole?  - ProProfs

    What continent houses the northern, magnetic pole? 

    • Africa 

    • Asia 

    • Oceania 

    • Australia 

    Correct Answer
    A. Australia 
    Explanation
    The correct answer is Australia. The northern, magnetic pole is located in the continent of Australia.

    Where is the point where the magnetic field is vertical?  - ProProfs

    Where is the point where the magnetic field is vertical? 

    • Local pole 

    • South pole 

    • Global pole 

    • North pole 

    Correct Answer
    A. Local pole 
    Explanation
    The correct answer is "Local pole". The local pole refers to a specific point on the Earth's surface where the magnetic field lines are vertical, meaning they are perpendicular to the surface. This point is different from the North and South poles, which are the points where the Earth's magnetic field lines are directed vertically into or out of the Earth. The local pole can vary depending on the location and can be found using a compass or magnetic field measurements.

    Which of these is not part of the magnetosphere?  - ProProfs

    Which of these is not part of the magnetosphere? 

    • Bow shock 

    • Magnetosheath 

    • Northern tail 

    • Eastern tail lobe 

    Correct Answer
    A. Eastern tail lobe 
    Explanation
    The Eastern tail lobe is not part of the magnetosphere. The magnetosphere is the region around a planet that is influenced by its magnetic field. It includes the bow shock, which is the boundary where the solar wind is slowed down and deflected by the magnetosphere, the magnetosheath, which is the region between the bow shock and the magnetopause, and the northern tail, which is the elongated region of the magnetosphere that extends away from the planet in the direction opposite to the Sun. However, the Eastern tail lobe is not a recognized component of the magnetosphere.
