    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is incorrect. Pluto is not the planet closest to the Sun. In fact, Pluto is no longer considered a planet by the International Astronomical Union (IAU). The planet closest to the Sun is Mercury, which is heavily cratered due to its proximity to the Sun and its lack of atmosphere to protect it from impacts.

    Rate this question:

  • 19. 

    A  comet is a meteoroid that strikes Earth.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A comet is not a meteoroid that strikes Earth. Comets are celestial objects composed of ice, dust, and rocky particles that orbit the Sun. When a comet gets close to the Sun, the heat causes the ice to vaporize, creating a glowing coma and a tail. While meteoroids are small rocky or metallic objects that travel through space, comets are distinct from them. Therefore, the statement that a comet is a meteoroid that strikes Earth is false.

    Rate this question:

  • 21. 

    The atmosphere on Mars is much thinner than Earth's.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because Mars has a much thinner atmosphere compared to Earth. The atmospheric pressure on Mars is about 0.6% of Earth's, which means the air density is significantly lower. This thin atmosphere makes it impossible for humans to breathe without the aid of specialized equipment. The lack of a thick atmosphere also contributes to the extreme temperatures on Mars, as it cannot retain heat as effectively as Earth's atmosphere. Additionally, the thin atmosphere on Mars allows more harmful radiation from the sun to reach the surface, making it less hospitable for life as we know it.

    Rate this question:

  • 22.

    The sun was formed as cloud fragments contracted and the temperature at the core increased to the point nuclear fusion began.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that the sun was indeed formed as cloud fragments contracted. As these fragments came together, gravity caused them to collapse, leading to an increase in temperature at the core. Eventually, the temperature became high enough for nuclear fusion to occur, resulting in the formation of the sun.

    Rate this question:

  • 26. 

    _________ published the Sun-centered model of the solar system in 1543.

    • Kepler

    • Magellan

    • Copernicus

    • Galileo

    Correct Answer
    A. Copernicus
    Explanation
    Copernicus published the Sun-centered model of the solar system in 1543. This model, known as the heliocentric model, proposed that the Sun is at the center of the solar system, with the planets including Earth orbiting around it. This was a significant departure from the prevailing geocentric model, which placed Earth at the center of the universe. Copernicus' work laid the foundation for our modern understanding of the solar system and revolutionized our view of the cosmos. Kepler, Magellan, and Galileo were also notable figures in the field of astronomy, but they did not publish the Sun-centered model.

    In the early 1600's, Johannes Kepler discovered that the shape of the planets orbits are _____________.

    • Parabolic

    • Circular

    • Elliptical

    • Spherical

    Correct Answer
    A. Elliptical
    Explanation
    Johannes Kepler discovered in the early 1600s that the shape of the planets' orbits is elliptical. This means that the planets do not follow a perfect circle in their paths around the sun, but rather an elongated shape called an ellipse. This discovery was a significant breakthrough in understanding the motion of celestial bodies and laid the foundation for Kepler's laws of planetary motion.

  • 40. 

    __________ are small pieces of dust and rock moving through space.

    • Comets

    • Meteors

    • Meteoroids

    • Meteorites

    Correct Answer
    A. Meteoroids
    Explanation
    Meteoroids are small pieces of dust and rock moving through space. Comets are icy bodies that also contain dust and rock, but they are different from meteoroids as they have a tail when they approach the sun. Meteors are meteoroids that enter Earth's atmosphere and burn up, creating a streak of light in the sky. Meteorites are the remnants of meteoroids that survive the journey through the atmosphere and land on Earth's surface. Therefore, the correct answer is meteoroids.

    Rate this question:

    Scientists theorize that the asteroid belt did not form a planet because____________.

    • Jupiter's gravity kept it from forming

    • Some of the particles were too large

    • It was too rocky

    • Some of the particles moved too slowly

    Correct Answer
    A. Jupiter's gravity kept it from forming
    Explanation
    The correct answer is "Jupiter's gravity kept it from forming." Scientists believe that the gravitational pull of Jupiter disrupted the process of planet formation in the asteroid belt. Jupiter's strong gravity prevented the particles in the belt from coming together and forming a planet. Instead, the gravitational forces from Jupiter caused the particles to remain scattered and prevented them from coalescing into a larger celestial body.

    The atmosphere surrounding the 4 outer planets consists primarily of what two gases? 

    • Hydrogen and helium

    • Helium and carbon dioxide

    • Hydrogen and carbon dioxide

    • Methane and carbon dioxide

    Correct Answer
    A. Hydrogen and helium
    Explanation
    The atmosphere surrounding the 4 outer planets consists primarily of hydrogen and helium. These two gases are the most abundant elements in the universe and make up the majority of the composition of gas giants like Jupiter and Saturn. Hydrogen is the most abundant element in the universe, while helium is the second most abundant. The other options, helium and carbon dioxide, hydrogen and carbon dioxide, and methane and carbon dioxide, are not accurate because carbon dioxide and methane are not the primary gases found in the atmospheres of the outer planets.

    Rate this question:

  • 43. 

    When small pieces of rock moving through space enter Earth's atmosphere and completely burn-up they are called __________.

    • Comets

    • Meteors

    • Meteorites

    • Asteroids

    Correct Answer
    A. Meteors
    Explanation
    When small pieces of rock moving through space enter Earth's atmosphere, they experience intense heat and friction, causing them to burn up completely before reaching the surface. These burning rocks are known as meteors. Comets are icy bodies that also enter Earth's atmosphere, but they usually survive the journey and may be visible as bright streaks with a tail. Meteorites, on the other hand, are meteors that manage to reach the Earth's surface without completely burning up. Asteroids are larger rocky bodies that orbit the Sun and can also enter Earth's atmosphere, but they are not specifically referred to as meteors.

    • Venus

    • Mars

    • Jupiter

    • Saturn

    Correct Answer
    A. Venus
    Explanation
    Galileo supported Copernicus' sun centered model by observing the phases of Venus with his telescope. This observation provided evidence for the heliocentric model, as the phases of Venus could only be explained if it revolved around the Sun. This supported Copernicus' theory that the Sun was at the center of the solar system, contradicting the prevailing geocentric model.
