    Occurs when plates in the Earth’s crust grind against each other:

    • A.

      A. Earthquake

    • B.

      Mountain formation

    • C.

      Trench formation

    • D.

    Correct Answer
    A. A. Earthquake
    Explanation
    When plates in the Earth's crust grind against each other, it causes a release of energy that results in vibrations or shaking of the Earth's surface. This phenomenon is known as an earthquake. Earthquakes can occur along faults, which are fractures in the Earth's crust where the plates are in contact. The movement of the plates, either sliding past each other, colliding, or moving apart, causes stress to build up along the fault line. Once the stress exceeds the strength of the rocks, it is released as seismic waves, causing an earthquake.

    Occurs when one plate in the Earth’s crust slides under another plate:

    • A.

      Trench formation

    • B.

      Volcanic eruption

    • C.

      Earthquake

    • D.

      Mountain formation

    Correct Answer
    A. Trench formation
    Explanation
    Trench formation occurs when one plate in the Earth's crust slides under another plate. This process is known as subduction, where the denser oceanic plate sinks beneath the less dense continental plate. As the oceanic plate descends into the mantle, it creates a deep trench on the ocean floor. This process is associated with the formation of volcanic arcs and can lead to the occurrence of earthquakes as the plates interact and release built-up stress. Mountain formation, on the other hand, is typically caused by the collision of two continental plates, while volcanic eruptions are caused by the release of magma from the Earth's mantle.

    • C.

      Trench formation

    • D.

      Volcanic eruption

    Correct Answer
    D. Volcanic eruption
    Explanation
    Volcanic eruption is the correct answer because it occurs when the Earth's mantle, which is located beneath the Earth's crust, pushes through the crust and releases magma, gases, and other materials onto the surface. This process creates volcanic activity, such as the eruption of lava, ash, and gases from a volcano. Unlike earthquakes, mountain formation, and trench formation, which are caused by tectonic plate movements, volcanic eruptions specifically involve the release of molten rock and other materials from beneath the Earth's surface.
