I want to test a new fertilizer, to find the best concentration for my garden. To do this, I plan to divide my garden into four sections.

Section A. I will use 5 grams of fertilizer per gallon each time I fertilize.

Section B. I will use 10 grams of fertilizer per gallon each time I fertilize.

Section C. I will use 15 grams of fertilizer per gallon each time I fertilize.

For section D, how much fertilizer per gallon should I use?

  1. 20 grams of fertilizer per gallon.

    No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer.
  2. 30 grams of fertilizer per gallon.

    No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer.
  3. 1 gram of fertilizer per gallon.

    No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer.
  4. No fertilizer at all.

    Yes. For this type of experiment, you need to have a control group. That is a group of test subjects that you do not do anything to. If the control group with no fertilizer grows just as well as the other groups, then I would know that the fertilizer was not working.

In August of 2004, Hurricane Charley removed over six feet of sand from the beach at St. Augustine. Was that an example of erosion, weathering, both, or neither?

  1. Erosion

    Yes! This is an example of erosion. The sand was moved by wind and water.

    The term "weathering" causes confusion because it sounds like it has something to do with weather. In Earth Science, weathering means "breaking apart." Weathering breaks rocks apart. Erosion carries the pieces of rock to a different location.

  2. Weathering

    No. While this was caused by weather, it is not an example of weathering. Keep in mind that weathering means breaking down rocks into smaller pieces. The sand was not broken into smaller pieces. It was just moved from one place to another (erosion).

  3. Both erosion and weathering

    No. This was erosion, but not weathering.
  4. Neither erosion nor weathering

    No. Since the sand was moved, it was erosion.

Are the ocean waves crashing against this rock an example of:

  1. Erosion

    Partially right! This is an example of erosion. Sand and bits of the rock are being moved by the waves..
  2. Weathering

    Partially right! This is an example of weathering too. Weathering is when a rock is broken into smaller pieces. The waves and the sand they carry are slowly grinding away these rocks.

  3. Both erosion and weathering

    Yes! The rock is being broken into smaller pieces by the waves (weathering), and the pieces are also being carried away by the waves (erosion).
  4. Neither erosion nor weathering

    No. Both weathering and erosion are happening here.

The white, fluffy part of the Salsify plant is very similar to the fluffy part of a Dandelion plant. What is its function?

  1. Pollinating the seeds.

    No. Pollination occurs with the flower, not with the fluffy part of the seed.
  2. Producing the seeds.

    No. The fluffy part is part of the seed. It does not produce the seed.
  3. Dispersing the seeds.

    Yes! The fluffy part of the seed catches the wind, letting a breeze scatter the seeds over a large area.
  4. Germinating the seeds.

    No. Germination occurs after the seed reaches the proper conditions, with soil and water.

This is called Marble. It was once limestone, but heat and pressure changed it, recrystallizing the calcite and distorting the layers. What kind of rock is it?.

  1. Igneous

    No. Igneous rocks formed from magma or lava. This is not an igneous rock.
  2. Sedimentary

    No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. When it was limestone it was a sedimentary rock, but not now.
  3. Metamorphic

    Yes!. This marble been changed by heat and pressure from a different kind of rock. It is metamorphic.
  4. Marble is not a rock.

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