In testing this piece of quartz, I found that it would scratch glass. What property was I testing?
-
Hardness
Yes! Hardness is a substance's resistance to being scratched. With a hardness of 7, quartz is hard enough to scratch glass. -
Cleavage
No. Cleavage is the tendency of a mineral to break along planes of weakness to produce pieces with flat, smooth sides. Cleavage involves breaking, not scratching. -
Fracture
No. Fracture is a property of minerals that do NOT break along planes of weakness to produce flat, smooth sides. This involves breaking, not scratching. -
Streak
No. Streak is a test to see the color of a mineral when it is ground into a powder by scratching it on a porcelain streak plate. For streak, we are powdering the mineral, not scratching another substance.

Which of the following is NOT a characteristic of ALL mammals?
-
All mammals have hair.
No. All mammals DO have hair. Even whales and dolphins have some hair on their skin. -
All mammals give birth to live young.
Yes! While most species of mammals give birth to live young, a few (platypus, echidna) lay eggs. -
All mammals have mammary glands.
No. All mammals DO have mammary glands. In females, these glands can produce milk to feed their young. -
All mammals have three bones in their inner ear.
No. All mammals DO have three bones in their inner ear. These bones are called the malleus, the incus, and the stapes. They transfer vibration from the ear drum to the inner ear.

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 brown spots on this fern contain spores. How are spores different from seeds?
-
Spores are much smaller, because they do not contain stored food for the young plant.
That is part of the answer. Most seeds contain stored food for the developing plant. Orchid seeds are an exception.. -
Spores are a form of asexual reproduction.
That is part of the answer. Spores contain only the genetic material from the parent plant. -
Spores develop into a different kind of plant from the parent.
This is part of the answer. Ferns have alternation of generations, which means that the spores grow into a plant called a prothallia. The prothallia produces male and female sex cells, which join, and grow into another fern plant. -
All of the above.
Yes! All three of the answers are correct.
