When water freezes into ice, its volume increases. What happens to its mass?

  1. It increases.

    No. When water freezes, it takes up more space, but the mass stays the same.
  2. It stays the same.

    Yes. When water freezes, it expands to take up more space, but its mass stays the same. Mass is the measure of how much "stuff" is there. Freezing water does not create new water or add more "stuff". It just makes the water take up more space.
  3. It decreases.

    No. The mass stays the same, even when the water freezes.
  4. Water does not have mass.

    No. Everything that is made out of matter has mass.

Eyeglasses and camera lenses change the path of light to focus an image. Which of the following is responsible for that change?

  1. Refraction

    Yes! Refraction bends light as it moves from one substance to another. By bending the light, we can use refraction to focus the image in a camera, or to correct the focus of the lens in our eyes.
  2. Reflection

    No. While some light is reflected from a lens, that does not help us focus the image.
  3. Absorption

    No. The lens is clear, telling us that very little of the light is being absorbed. Absorption does not help the lens focus.
  4. Diffusion

    No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the image cloudy and blurry, not help focus it.

These building stones are made of a rock called coquina. The rock is almost entirely made up of pieces of fossil sea shells. What kind of rock is it?

  1. Igneous

    No. Igneous rocks formed from magma or lava. That would have melted and destroyed the fossil shells. This is not an igneous rock.
  2. Sedimentary

    Yes! Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. These bits of shell were deposited by water, so coquina is a Sedimentary rock.
  3. Metamorphic

    No. Coquina has not been changed by heat and pressure from a different kind of rock, so it is not metamorphic.
  4. Coquina is not a rock.

    No. Coquina is a naturally occurring solid that forms large layers in the Earth. Coquina is a rock.

As we look at the rock cycle, we can see that heat and pressure can change a sedimentary rock into a metamorphic rock. What would change a metamorphic rock into a sedimentary rock?

  1. More heat and pressure

    No. More heat and pressure would cause more metamorphic change.
  2. Erosion and deposition

    Yes. If the rock was eroded and deposited, that would form a sedimentary rock.
  3. Melting and cooling

    No. Melting the rock and then cooling it would produce an igneous rock.
  4. A metamorphic rock cannot become a sedimentary rock

    No. In the rock cycle, a rock from any group (igneous, sedimentary, metamorphic) can be changed into a rock from any group.

Rainbows are produced by:

  1. Refraction

    Partly correct. Light entering the raindrop is reflected off of the back surface.
  2. Reflection

    Partly correct. As the light passes from air to water, and from water to air, the light is bent or refracted. Different colors are refracted different amounts, separating the colors.
  3. Both reflection and refraction

    Correct! When you see a rainbow, the sun will always be behind you. (There are other, similar looking phenomena which you see when facing the sun, but they are not rainbows.) The sunlight enters each raindrop, is refracted (bent). Different colors are refracted different amounts. When the light hits the far side of the raindrop, part of it goes on through, and part of it is reflected back towards the sun (and towards you.) As it passes leaves the drop, the difference in density from water to air refracts (bends) the light even more, separating the colors into bands for the rainbow.
  4. Neither reflection no refraction

    No. One or both take part in producing the rainbow.
