This is called Obsidian. It is formed from molten lava that cools so quickly that it forms a natural glass instead of crystals. What kind of rock is it?.
-
Igneous
Yes! Igneous rocks formed from magma or lava. This is an igneous rock. -
Sedimentary
No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. This is not a sedimentary rock. -
Metamorphic
No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. Instead of being changed, this got hot enough to completely melt, so it is not metamorphic. -
Obsidian is not a rock.
No. Obsidian is a naturally occurring solid that forms large layers in the Earth. Obsidian is a rock.

Which part of the food web does this mushroom fit into?
-
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. -
Primary Consumer.
No. Primary consumers eat producers. This mushroom does not eat living plants. -
Secondary Consumer
No. Secondary consumers eat other consumers. This mushroom does not eat living animals. -
Decomposer
Yes! Decomposers break down dead and decaying organisms. This mushroom gets its energy from decaying organisms in the soil.

This is Johnson Wash, that runs down the middle of the canyon where we live. It is usually dry, but when it rains up north, we get flash floods. Is this an example of erosion, weathering, both, or neither?
-
Erosion
Yes, the is partially correct! You can tell by the muddy appearance of the water that it is carrying sand, clay and dirt along with it. Erosion is when bits of rock are moved by wind, water, ice, or gravity, so this counts as erosion.. -
Weathering
Yes, the is partially correct! 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 into smaller bits. The fast moving water causes smaller rocks to smash into larger rocks, breaking them apart. -
Both erosion and weathering
Yes! The flash flood in this photo is causing weathering, and erosion. As the flood decreases, and the water slows down, it will drop the sand, clay, dirt, and rocks in a process called deposition. -
Neither erosion nor weathering
No. This flash flood is causing both weathering and erosion.

The "strings" in a stalk of celery are made up of xylem and phloem. Which part of your body comes closest to serving the same function?
-
Skeleton
No. Your skeleton provides support and protection. In plants, the cell wall provides support and protection. -
Intestines
No. Your intestines allow you to absorb nutrients from your food. Plants make their own food, so they do not need a digestive system. -
Nerves
No. Your nerves carry signals to let the parts of your body communicate. They carry messages for your senses, to move your muscles, etc. Instead of having nerves, plants release chemicals that signal other parts of the plant. -
Blood Vessels
Yes! Your blood vessels carry water and nutrients to different parts of your body. In plants, the xylem is made up of tubes that carry water and some nutrients from the roots upwards to other parts of the plant. The phloem is made up of tubes that carry the sugar produce by photosynthesis to other parts of the plant. While they work in very different ways, your blood vessels serve basically the same function (carrying water and nutrients) as the xylem and phloem in plants.
