  • 2. 

    Who formulated the geocentric theory?

    • A.

      Newton

    • B.

      Galileo

    • C.

      Homer Simpson

    • D.

      Ptolemy

    • E.

      Copernicus

    Correct Answer
    D. Ptolemy
    Explanation
    Ptolemy formulated the geocentric theory. This theory proposed that the Earth is at the center of the universe and all celestial bodies revolve around it. Ptolemy's geocentric model was widely accepted for centuries until it was eventually replaced by the heliocentric model proposed by Copernicus. Ptolemy's theory had a significant influence on the understanding of the cosmos during the ancient and medieval periods.

    Who formulated the heliocentric theory?

    • A.

      Newton

    • B.

      Galileo

    • C.

      Homer Simpson

    • D.

      Ptolemy

    • E.

      Copernicus

    Correct Answer
    E. Copernicus
    Explanation
    Copernicus is the correct answer because he formulated the heliocentric theory. The heliocentric theory states that the Earth and other planets revolve around the Sun, which was a significant departure from the prevailing geocentric theory. Copernicus' work laid the foundation for modern astronomy and challenged the long-held belief that the Earth was the center of the universe. His book, "De Revolutionibus Orbium Coelestium," published in 1543, presented his heliocentric model and marked a major milestone in the scientific understanding of the solar system.

    • E.

      20.1 degrees

    Correct Answer
    A. 23.5 degrees
    Explanation
    The axial tilt of the Earth refers to the angle at which its axis is tilted in relation to its orbit around the Sun. This tilt is responsible for the changing seasons on Earth. The correct answer is 23.5 degrees, which means that the Earth's axis is tilted at an angle of 23.5 degrees relative to its orbital plane.

    When the Earth is directly between the Sun and the moon, it is called a ________ eclipse.

    • A.

      Lunar

    • B.

      Transit

    A. Lunar
    Explanation
    When the Earth is directly between the Sun and the moon, it is called a lunar eclipse. During a lunar eclipse, the Earth blocks the sunlight from reaching the moon, causing the moon to appear dark or reddish in color. This occurs when the moon is in the full moon phase and aligned with the Earth and the Sun in a straight line.

    Correct Answer
    B. 67,000
    Explanation
    The correct answer is 67,000 miles per hour. This is the approximate speed at which the Earth orbits around the Sun. The Earth's orbit is not a perfect circle, so its speed varies slightly throughout the year. However, on average, it travels at a speed of about 67,000 miles per hour.

      3 (Crust, Mantle, Core)

    • B.

      2 (Crust and Core)

    • C.

    • E.

      4 (Crust, Mantle, Outer Core, Inner Core)

    Correct Answer
    E. 4 (Crust, Mantle, Outer Core, Inner Core)
    Explanation
    The Earth is made up of four layers: the crust, mantle, outer core, and inner core. The crust is the outermost layer, followed by the mantle which is a thick layer of hot, solid rock. Beneath the mantle is the outer core, which is a liquid layer made of molten iron and nickel. Finally, at the center of the Earth is the inner core, which is a solid ball of iron and nickel. These layers have different compositions and physical properties, and together they make up the structure of the Earth.

    • A.

      Clearwater Lakes Crater

    • B.

      Barringer Crater

    • C.

      Caloris Basin

    • D.

      Vredefort Ring

    • E.

      Lake Tahoe

    Correct Answer
    D. Vredefort Ring
    Explanation
    The Vredefort Ring is the largest known impact crater on Earth. It is located in South Africa and is estimated to be about 300 kilometers in diameter. The crater was formed around 2 billion years ago when a massive asteroid or comet collided with Earth. The impact was so powerful that it caused the Earth's crust to buckle and form a ring-shaped structure. Over time, erosion and geological processes have modified the crater, but its size and unique geological features still make it the largest known impact crater on our planet.

This is supported by scientific evidence which states that approximately 71 percent of the Earth's surface is covered by water, including oceans, seas, lakes, rivers, and ice caps. Additionally, water is also found underground in the form of groundwater. Therefore, it is accurate to say that the Earth is comprised of 75 percent water.

    Mount St. Helens is considered a ____________ volcano.

    • A.

      Composite

    • B.

      Singular

    • C.

      Complex

    • D.

      Sheild

    • E.

      Subglacial

    Correct Answer
    A. Composite
    Explanation
    Mount St. Helens is considered a composite volcano because it is composed of both lava flows and explosive eruptions. Composite volcanoes, also known as stratovolcanoes, are characterized by their steep slopes and alternating layers of lava, ash, and pyroclastic materials. They are typically found in subduction zones where one tectonic plate is forced beneath another. The explosive eruptions of composite volcanoes can be highly destructive, as seen in the 1980 eruption of Mount St. Helens, which caused significant damage and loss of life.
