One test for identifying minerals involves rubbing the mineral on a rough tile, and looking at the color of the mark it leaves. This test is called:
-
Cleavage
No. Cleavage is when a mineral breaks along planes of weakness to form flat surfaces. -
Hardness
No. Hardness is the resistance of a mineral to being scratched by other substances. -
Fracture
No. Fracture is when a mineral breaks but does not show cleavage. -
Streak
Yes. The streak test examines the color of the mineral when it is powdered by rubbing it on a rough tile or streak plate. While the actual color of a mineral can vary, it will always produce the same color streak.

I used this piece of calcite to scratch this penny. Then I used the penny to scratch the piece of calcite. What does that tell us?
-
It tells us that I did the test wrong.
No. The test was done correctly. -
It tells us that they both have the same hardness.
Yes! You test the hardness of a mineral by testing to see what will scratch it. If two substances scratch each other, they have the same hardness. -
It tells us that calcite is not a mineral.
No. Scratching a specimen will not tell you if it is a mineral. -
It tells us that calcite has cleavage.
No. You do not test for cleavage by scratching a mineral.

Which of these processes forms the VISIBLE part of a cloud?
-
Evaporation
No. Evaporation changes liquid water into water vapor. Water vapor is an invisible gas, so it is not the visible part of the cloud. -
Condensation
Yes! Condensation changes water vapor into droplets of liquid water to form the cloud. These are just like the tiny water droplets that form fog, letting you see the cloud. -
Precipitation
No. Precipitation can fall from a cloud, but it is not the process that forms the cloud. -
Convection
No. Convection carries the water vapor upwards so it can cool and condense, but condensation is what forms the visible part of the cloud.

You have probably seen patterns of light like this in a pool of water. What causes it?
-
Absorption
No. If the light was being absorbed, the pattern would be dark instead of bright. -
Diffusion
No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the entire area brighter, not a specific pattern. -
Reflection
No. While the light has to reflect back to your eye for you to see it, reflection does not cause this pattern. -
Refraction
Yes! Refraction bends light. Waves and ripples on the surface of the water act just like the curved surface of a lens. This bends the light into patterns that have shapes similar to the ripples on the water's surface.

How can there be rain if this area is a desert?
Answer:
It is important to understand the difference between climate and weather. Weather is what is happening now. Climate is determined by looking at the weather data over a long period of time, often several decades. To be classified as a desert climate, the area has an average annual rainfall of 7.87 inches of rain or less. That tells us that it does sometimes have rain, just not very often.
