    The correct answer is Volcanic eruption.

    Key Points

    Volcanic eruptions are direct sources of information about the interior of the earth.

    Volcanic eruption forms another source of obtaining direct information.

    As and when the molten material (magma) is thrown onto the surface of the earth, during a volcanic eruption it becomes available for laboratory analysis.

    Additional Information

    The indirect sources include gravitation, magnetic field, and seismic activity.

    The study of seismic waves provides a complete picture of the layered interior.

    It has helped scientists to understand the structure of the interior of the earth.

    Reflection causes waves to rebound whereas refraction makes waves move in different directions.

    The variations in the direction of waves are inferred with the help of their record on the seismograph.

    Select the correct answer using the codes given below:

    A 2, 3 and 5 only B 1, 3 and 4 Only C 1 and 3 only D 1, 2, 3, 4 and 5l Open in App Solution

    The correct option is C

    1 and 3 only

    Explanation:

    Mining, drilling and volcanic eruption are examples of direct sources. During the process of mining and drilling rocks and minerals are extracted which gives information that there is a layer system in the crust. Volcanic eruption suggests that there is some zone inside the earth which is very hot and in liquid condition.

    Seismic waves, gravitational field, magnetic field, falling meteors etc. are examples of indirect sources. They are very important for knowing about the earth's interior.
