JustSayHi - Science Quiz

I got one question wrong. But in taking the test I encountered several questions that were poorly worded, or where the 'right' answer wasn't actually the right answer. I remember this in HS too. It would've been amusing to hand a critique like the one below back to one of my teachers.

  1. Northern garter snakes exhibit a unique behavior in which they gather in deep dens by the hundreds or thousands. They then coil together in a huge ball. This behavior could help to

    Reduce heat loss

    This is poorly worded. The behavior 'could' be for a lot of different reasons. The prevaling theory is that it is a mechanism to reduce heat loss.

  2. This type of rock is buried deep within the earth's crust

    Metamorphic rock

    No, it isn't. It was once there, but now it isn't, or at least the rock we manage to see and call metamorphic isn't.

  3. Comets are composed of ____ left over from the formation of our solar system.

    Dirty ice

  4. Which form of solar radiation causes sunburn?


  5. A large truck and a small car fall with the same exact velocity. Which vehicle has more momentum?

    The truck

  6. Shock waves pass through the layers of the earth after an earthquake. The waves vary as they pass through different materials in the earth. Shock waves are also called _____ waves


    Shock waves in general are not usually called seismic waves. Shock waves of the particular type just described are called that.

  7. _____ are hurtling through space and not captured in Earth's atmosphere.


  8. What causes tides in the ocean?

    The moon's gravitational pull

    Predominantly yes, but the Sun's gravitational pull plays a big enough role that the position of the Sun is a factor in computing tide tables. And, of course the gravitational pull of everything else plays a role too, but none of those things have enough of an effect to be a factor in the tide tables, not even when all the planets align.

  9. What is the name given to water loss to the atmosphere by green plants?


  10. Tectonic plates sliding past one another can cause...


  11. ow do mammals respire?

    Both aerobically and anaerobically

    The one I got wrong. I'm still not sure why. My guess is they're thinking about the fact that muscles sometimes use metabolic pathways that don't involve oxygen and that's how lactic acid and muscle aches come into existence, but I might be totally wrong.

  12. Is the offspring of an asexual organism genetically identical to its parent?


    If that were actually true, evolution couldn't happen for asexual organisms. So, it's just mostly true.

  13. What are the two main functions of fruit for a plant?

    To disperse and protect the seeds

  14. A stone dropped from a helicopter takes 10 seconds to hit the sea below. What is its final velocity? (Assume that the acceleration due to gravity is 10 m/s2)

    100 m/s

  15. The colour of a pure red rose in white sunlight is a result of the fact that:

    The rose reflects only red light.

  16. The source of energy for the Earth's water cycle is the

    Sun's radiation

  17. Which BEST describes the surface of the Earth over billions of years?

    High mountains gradually wear down as new mountains are continually being formed.

  18. What is the most abundant element in the universe?


    Should be "Currently, what is the most abundant element in the Universe." but that's kind of nit-picky. I bet lots of people answer 'silicon' to this one, but that's the most abundant element in the Earth's crust, not in the Universe.

  19. When you bend your arm at the elbow, the bones and muscles in your arm are acting as a system. What simple machine does this system represent?


  20. Which is the most basic unit of living things?


    This can be nit-picked as well, but it's not really worth it.

  21. What is the process by which plants use carbon dioxide, sunlight, and water to produce energy (and oxygen)?


  22. How are warm-blooded animals different from cold-blooded animals?

    Warm-blooded animals normally maintain a fairly constant internal temperature at all air temperatures.

  23. Which is made with the help of bacteria?


  24. If a neutral atom loses an electron, what is formed?

    An ion

  25. Which is NOT an example of a chemical change?

    Boiling water

  26. Which of the following is a gaseous planet?

Looking for payday loans?

I only got a B, but...well, the ones I got wrong, I mostly got wrong because of the wording of the answers. There were times when I was like, "I know the answer, but none of these choices really seem to mean that."
