Answers and explanations

  1. Question: Which planet in our solar system rotates on its side, giving it extreme seasonal changes?
    Answer: Uranus
    Explanation: Uranus has an axial tilt of about 98°, so it effectively rolls along its orbit; seasons there last over 20 years. People often guess Neptune or Saturn, but their tilts are much smaller.
  2. Question: What gas do plants mainly take in during photosynthesis to make sugars?
    Answer: Carbon dioxide
    Explanation: Plants fix CO2 into organic molecules using sunlight energy; water and light are also required, so 'oxygen' and 'nitrogen' are common wrong guesses.
  3. Question: What is the primary unit used to measure electrical resistance?
    Answer: Ohm
    Explanation: Resistance is measured in ohms (symbol Ω) named after Georg Ohm; volts and watts are related but measure voltage and power, not resistance.
  4. Question: Which element makes up the majority of the Sun's mass?
    Answer: Hydrogen
    Explanation: About 75% of the Sun's mass is hydrogen, fused into helium in its core; many think helium is most abundant because it's the product of fusion.
  5. Question: What particle carries the electromagnetic force between charged particles?
    Answer: Photon
    Explanation: The photon is the force carrier for electromagnetism in quantum theory; electrons are charged particles themselves, not the force carriers.
  6. Question: Which scientist proposed the three laws of motion that form the basis of classical mechanics?
    Answer: Newton
    Explanation: Isaac Newton formulated the three laws in the 17th century, crucial for classical physics; people sometimes confuse him with Einstein who developed relativity later.
  7. Question: What type of rock forms when molten rock cools and solidifies?
    Answer: Igneous
    Explanation: Igneous rocks crystallize from magma or lava; sedimentary and metamorphic rocks form by other processes, which is a common misconception.
