How hot does an area have to be to be classified as a desert?

Answer:

Deserts are defined by lack of precipitation, not by temperature. They are areas where precipitation minus evaporation yields less than 10 inches of rain per year. The largest desert on Earth is in Antarctica, a very cold place.

NGSS

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.

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.

None of these layers have been turned upside down. Based on the Law of Superposition, which layer is the oldest?

  1. A

    No. Layer A is on top of layer B, so it is younger than layer B. That means that it is not the oldest.
  2. B

    No. If you look at layer B, it is on top of layer C, which means that it is younger than layer C. B is not the oldest.
  3. C

    No. Look closely at the top part of layer C. The top part of layer C is on top of part of layer D. That tells us that layer C is younger than layer D.
  4. D

    Yes! This one is a bit tricky, because of the way the rocks were formed. Layer D formed first, as a flat, horizontal layer. Erosion weathered the left part of D away, forming a sloping hillside. Image the photo with layers A, B, and C erased, and it looks like a sloping hillside.

    Next, a nearby volcano erupted, spewing out lots of volcanic ash. The ash covered the hillside, forming layer C.

    Next, lava from the volcano flowed down over the ash, forming layer B.

    Later, the volcano erupted again, depositing another layer of volcanic ash to form layer A. After that, layer A was covered by another layer of lava, and then another layer of volcanic ash.

    So A is the youngest, followed by B, then C, and D is the oldest.

Which part of the food web does this mushroom fit into?

  1. Producer.

    No. A producer captures energy from sunlight, and stores it as food. To do that, the organism needs to contain chlorophyll. This mushroom cannot use the energy of sunlight to produce its own food.
  2. Primary Consumer.

    No. Primary consumers eat producers. This mushroom does not eat living plants.
  3. Secondary Consumer

    No. Secondary consumers eat other consumers. This mushroom does not eat living animals.
  4. Decomposer

    Yes! Decomposers break down dead and decaying organisms. This mushroom gets its energy from decaying organisms in the soil.
