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.

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.

wood and ashes

The wood in this pile will be reduced to this much ash when it is burned. What happens to the rest of the mass from the wood?

  1. It was converted into energy.

    No. Burning does not convert matter into energy.
  2. It evaporated.

    No. While any moisture in the wood may have evaporated, wood itself does not evaporate.
  3. It was converted into water and carbon dioxide.

    Yes! Burning converts the cellulose in wood into water vapor and carbon dioxide. The white ash that is left behind is made up of the minerals and nutrients which were taken in by the plant's roots.
  4. The matter is still there. It just got smaller.

    No. If all of the matter was still there, the mass and weight would still be the same. The ash is much lighter than the wood, because the water vapor and carbon dioxide are now part of the air of the room. Still, if we could weigh all of the ash, water vapor, and carbon dioxide, the total mass would still be the same.

When Nancy and I moved from Florida to our new home in Utah, we found that many of the flowers we grew in Florida would not grow well here. Why?

  1. The soil is different.

    This is part of the answer. The soil here is mostly sand, and is very alkaline. The soil in Florida had much more organic matter and was more acidic. Plants that need rich soil do not grow well here.
  2. The climate is different.

    This is part of the answer. The climate in Utah is very different from Florida. The winters are MUCH colder (down to -20°F) and the summers are MUCH hotter (up to 125°F). The climate here is also much drier. When we lived in Jacksonville, FL, we got about 52 inches of rainfall each year. Here in Utah, we only get about 14 inches of rainfall each year. Some of the plants from Florida can grow here, but the ones that cannot stand the cold, heat, and dry conditions do not.
  3. The animals are different.

    This is part of the answer. The wildlife here is much different from the animals in Florida. There are insects here that eat plants that were not bothered by Florida insects. There are rock squirrels, western pocket gophers, jack rabbits, mule deer, and many other animals here that love to eat many kinds of flowers. Plants that do not have a bitter taste, spines, or other ways to discourage animals do not do well here.
  4. All of the above.

    Yes! All of the answers are correct. When you take an organism from one environment and put it into another, you may see different results. If the organism is not adapted for the new environment, it may die or not grow well. If it is very well adapted to the new environment, it may take over, crowding out some of the native organisms.

The large cracks in this rock are called expansion cracks. As the overlying rock erodes away, the rock expands, causing the cracks. The cracks are an example of:

  1. Erosion

    No. Erosion means that the pieces of rocks are being carried away. The overlying rocks have been eroded, but the cracks are not carrying the pieces to a new location.
  2. Weathering

    Yes! As the rocks expand unevenly, tension builds up. When there is enough stress, the rocks break. That breaking of large rocks into smaller pieces is called weathering.

  3. Both erosion and weathering

    No. The rocks are being broken (weathering), but the pieces are staying in place, so there is not erosion.
  4. Neither erosion nor weathering

    No. The cracks show that the rocks are breaking, which is weathering..
