    Newton discovered

    • That gravity is universal, it works the same everywhere.

    • That the sun is at the center of solar system

    • That all the galaxies are moving away from each other

    • That space and time is curved

    • That the world is round

    Correct Answer
    A. That gravity is universal, it works the same everywhere.
    Explanation
    Newton's discovery that gravity is universal and works the same everywhere is based on his law of universal gravitation. According to this law, every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This means that gravity not only affects objects on Earth, but also extends to all celestial bodies and throughout the universe. Newton's discovery revolutionized our understanding of gravity and laid the foundation for modern physics.

    The inner four planets of the solar system are

    • Terrestrial planets

    • Gas planets

    • Comets

    • Asteroid planets

    • The largest planets

    Correct Answer
    A. Terrestrial planets
    Explanation
    The correct answer is terrestrial planets. The inner four planets of the solar system, namely Mercury, Venus, Earth, and Mars, are known as terrestrial planets. These planets are primarily composed of rock and metal, and they have solid surfaces. Unlike gas planets, they have a relatively low mass and do not have a significant atmosphere. Comets are icy bodies that orbit the Sun, and asteroid planets do not exist as a distinct category. "The largest planets" is not an accurate description for the inner four planets.

    The "fuel" that burns in the center of a star like our sun is

    • Fossil fuel

    • Magic

    • The fusion of hydrogen into helium

    • Uranium fission into lighter elements

    • Solar energy

    Correct Answer
    A. The fusion of hydrogen into helium
    Explanation
    The correct answer is the fusion of hydrogen into helium. In the center of a star like our sun, hydrogen atoms undergo a process called nuclear fusion, where they combine to form helium. This fusion process releases a tremendous amount of energy in the form of light and heat, which is what powers the sun and allows it to shine. Fossil fuel, magic, uranium fission, and solar energy are not the correct answers because they do not accurately describe the process that occurs in the center of a star.

    How fast must the wind be blowing for a storm to be considered a hurricane?

    • 50 mph

    • 74 mph

    • 125 mph

    • 30 mph

    • 250 mph

    Correct Answer
    A. 74 mph
    Explanation
    A storm is considered a hurricane when the wind speed reaches 74 mph. This is the threshold at which a storm is classified as a hurricane according to the Saffir-Simpson Hurricane Wind Scale. Wind speeds below 74 mph would be classified as a tropical storm or a lesser category of storm. Wind speeds of 74 mph or higher indicate the destructive power and intensity that is associated with a hurricane.

    Hubble discovered

    • That gravity is universal, it works the same everywhere.

    • That the sun is at the center of solar system

    • That all the galaxies are moving away from each other

    • That space and time is curved

    • That the world is round

    Correct Answer
    A. That all the galaxies are moving away from each other
    Explanation
    Hubble's discovery that all the galaxies are moving away from each other is based on his observation of the redshift in the light emitted by galaxies. He noticed that the light from distant galaxies appeared to be shifted towards longer wavelengths, indicating that they were moving away from us. This observation led to the conclusion that the universe is expanding, with all galaxies moving away from each other. This discovery provided strong evidence for the Big Bang theory and revolutionized our understanding of the universe's evolution.

    Copernicus discovered

    • That gravity is universal, it works the same everywhere.

    • That the sun is at the center of solar system

    • That all the galaxies are moving away from each other

    • That space and time is curved

    • That the world is round

    Correct Answer
    A. That the sun is at the center of solar system
    Explanation
    Copernicus discovered that the sun is at the center of the solar system. This was a significant finding as it challenged the prevailing belief at the time that the Earth was at the center. Copernicus' heliocentric model proposed that the planets, including Earth, revolve around the sun, which revolutionized our understanding of the solar system. This discovery laid the foundation for modern astronomy and had a profound impact on our understanding of the universe.

    Rate this question:

  • 24. 

    The sun and planets were formed from

    • A huge cloud of gas and dust

    • A huge energy blast

    • Magic powers

    • Nothing

    • Atoms in space that came together under the electric force

    Correct Answer
    A. A huge cloud of gas and dust
    Explanation
    The correct answer is a huge cloud of gas and dust. This explanation is based on the widely accepted scientific theory of the formation of the solar system known as the nebular hypothesis. According to this theory, about 4.6 billion years ago, a massive cloud of gas and dust called the solar nebula collapsed under its own gravity. As it collapsed, it began to spin and flatten into a spinning disk. The central part of the disk became the Sun, while the material in the outer part of the disk came together to form the planets, moons, and other objects in the solar system.

    Cyanobacteria converted carbon dioxide and sunlight into

    • Oxygen

    • Nitrogen

    • Hydrogen

    • Carbon trioxide

    • Water

    Correct Answer
    A. Oxygen
    Explanation
    Cyanobacteria are photosynthetic microorganisms that use sunlight and carbon dioxide to produce oxygen through the process of photosynthesis. They contain pigments called chlorophyll which capture energy from sunlight and convert it into chemical energy. This energy is then used to split water molecules, releasing oxygen as a byproduct. Therefore, the correct answer is oxygen.

    • Terrestrial planets

    • Gas planets

    • Comets

    • Asteroid planets

    • The largest planets

    Correct Answer
    A. Gas planets
    Explanation
    The correct answer is gas planets because the outer four planets in the solar system, namely Jupiter, Saturn, Uranus, and Neptune, are primarily composed of gases such as hydrogen and helium. These planets have thick atmospheres and lack a solid surface, making them distinct from terrestrial planets like Earth and Mars. Additionally, gas planets are known for their large size compared to other planets in the solar system.

    Rate this question:

  • 27. 

    The electromagnetic force

    • keeps the quarks in a proton together

    • Keeps us on the ground

    • is responsible for nuclear decay

    • Keeps electrons in orbit around the nucleus

    • Is not so strong

    Correct Answer
    A. Keeps electrons in orbit around the nucleus
    Explanation
    The correct answer is "Keeps electrons in orbit around the nucleus". This is because the electromagnetic force is responsible for the attraction between negatively charged electrons and positively charged protons in an atom. This force keeps the electrons in their respective energy levels or orbits around the nucleus, preventing them from flying off into space. Without this force, electrons would not be able to maintain stable orbits and atoms would not exist as we know them.

    The planet with the highest density is

    • Saturn

    • Uranus

    • Neptune

    • Pluto

    • Earth

    Correct Answer
    A. Earth
    Explanation
    Earth has the highest density among the given options. Density is defined as the mass of an object divided by its volume. Earth's high density can be attributed to its composition, which consists of a dense core made up of iron and nickel, surrounded by less dense layers of rock and gas. This high density gives Earth its strong gravitational pull and allows it to retain its atmosphere. In comparison, the other planets listed have lower densities due to their different compositions and structures.

    Rate this question:

  • 29. 

    Earth's early atmosphere did not contain any

    • Carbon dioxide

    • Air

    • Oxygen

    • Helium

    • Water

    Correct Answer
    A. Oxygen
    Explanation
    During Earth's early formation, the atmosphere did not contain any oxygen. This is because oxygen was primarily produced by photosynthetic organisms, which did not exist at that time. The early atmosphere was composed mainly of gases such as carbon dioxide, nitrogen, water vapor, and small amounts of methane and ammonia. Oxygen began to accumulate in the atmosphere only after the emergence and proliferation of oxygen-producing organisms, such as cyanobacteria, through the process of photosynthesis.

    Einstien discovered

    • That gravity is universal, it works the same everywhere.

    • That the sun is at the center of solar system

    • That all the galaxies are moving away from each other

    • That space and time is curved

    • That the world is round

    Correct Answer
    A. That space and time is curved
    Explanation
    Einstein's theory of general relativity revolutionized our understanding of gravity by proposing that the presence of mass and energy curves the fabric of space and time. This means that objects with mass, like planets or stars, create a curvature in spacetime, causing other objects to move along curved paths. The theory explains various phenomena, such as the bending of light around massive objects and the gravitational waves observed from merging black holes. Therefore, the statement "that space and time is curved" accurately describes one of Einstein's significant discoveries.

    The furthest planet from the sun is

    • Saturn

    • Uranus

    • Neptune

    • Pluto

    • Earth

    Correct Answer
    A. Neptune
    Explanation
    Neptune is the furthest planet from the sun. It is located in the outer regions of our solar system, beyond Uranus. Although Pluto was considered the ninth planet in the past, it has since been reclassified as a "dwarf planet." Earth is the third planet from the sun, making it closer to the sun compared to Neptune. Saturn is also closer to the sun than Neptune, making it an incorrect answer. Therefore, Neptune is the correct answer as it is the furthest planet from the sun.

    The beginning of star formation starts with

    • Many different colors and sizes

    • Outward pressure created by the nuclear reactions

    • Dust and gas bumping into each other making the ball heat up

    • A bright flash of light

    • A cloud of dust and gas

    Correct Answer
    A. A cloud of dust and gas
    Explanation
    The correct answer is a cloud of dust and gas. Star formation begins with a cloud of dust and gas. These clouds are composed of various elements and molecules that come together due to gravity. As the cloud collapses under its own weight, it starts to heat up and the pressure increases. Eventually, the temperature and pressure become high enough for nuclear reactions to occur, leading to the formation of a star.

    Rate this question:

  • 40. 

    Pluto is not a planet because

    • It is not in orbit around the sun

    • It does not have enough gravity to pull itself into a spherical shape

    • It has not cleared the neighborhood of its orbit

    • It is made of ice and rock

    • It has rings

    Correct Answer
    A. It has not cleared the neighborhood of its orbit
    Explanation
    Pluto is not considered a planet because it has not cleared the neighborhood of its orbit. This means that there are other objects in Pluto's orbit that are of similar size or larger. According to the definition set by the International Astronomical Union (IAU), a planet must be the dominant gravitational body in its orbit and must have cleared its orbit of any other debris. Since Pluto shares its orbit with other objects in the Kuiper Belt, it does not meet this criterion and is therefore classified as a dwarf planet.

    Rate this question:

  • 41. 

    All the elements heavier than lithium were

    • Made in the center of stars

    • Created in the big bang

    • Created by black holes

    • Created by a huge cloud of gas and dust

    • Brought to the earth by comets

    Correct Answer
    A. Made in the center of stars
    Explanation
    The correct answer is "made in the center of stars" because elements heavier than lithium, such as carbon, oxygen, and iron, are formed through stellar nucleosynthesis. This process occurs in the core of stars during their life cycle, where high temperatures and pressures allow for nuclear fusion reactions to take place, creating heavier elements. These elements are then released into space through stellar explosions, such as supernovae, and eventually become part of new star systems and planetary bodies.

    When the sun runs out of hydrogen fuel

    • It will blow up in a supernova explosion

    • It will slowly cool down and become a white dwarf

    • It will become a planet

    • It will become a red giant

    • It will become a galaxy

    Correct Answer
    A. It will become a red giant
    Explanation
    When the sun runs out of hydrogen fuel, it will undergo a process called stellar evolution. As the core contracts and heats up, the outer layers of the sun will expand, causing it to become a red giant. During this phase, the sun will increase in size and become much brighter. Eventually, it will shed its outer layers and form a planetary nebula, leaving behind a dense, hot core known as a white dwarf. Therefore, the correct answer is that the sun will become a red giant.
