Which of the following forms of ice commonly occurs in the summer when air temperatures are well above freezing?

A: Hail

B: Snow

C: Frost

D: Freezing rain
Think about it, and when you think you know the answer, then click here.
While other kinds of frozen precipitation can form at high altitudes, in the summer they usually melt long before they reach the ground. Hail is made up of large enough chunks of ice that it usually remains frozen all the way to the ground, even during warm weather.

This snow fell when the temperature outside was 39°F. How can you get snow when the temperature is above freezing?
-
The wind made it feel colder, allowing it to snow.
No. While wind chill can make it feel colder, it does not actually make it colder. -
It was colder in the clouds where the snow formed.
Yes. Even when air temperatures at the surface are above freezing, the clouds can be much colder. If the air at the surface is not too warm, the snow can reach the ground without melting. -
Rain froze into snow when it hit the ground.
No. Freezing rain forms ice, not snow. Light, fluffy snow flakes form as they fall through the air, not after they hit the ground. -
This is really hail instead of snow.
No. Hail is made of large chunks of ice, not tiny flakes.

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.

The white, fluffy part of the Salsify plant is very similar to the fluffy part of a Dandelion plant. What is its function?
-
Pollinating the seeds.
No. Pollination occurs with the flower, not with the fluffy part of the seed. -
Producing the seeds.
No. The fluffy part is part of the seed. It does not produce the seed. -
Dispersing the seeds.
Yes! The fluffy part of the seed catches the wind, letting a breeze scatter the seeds over a large area. -
Germinating the seeds.
No. Germination occurs after the seed reaches the proper conditions, with soil and water.

The nucleus of the cell contains most of the cell's DNA. Which other structure in the cell contains DNA?
-
Mitochondria
Yes! Your mitochondria have their own DNA. Unlike the DNA in the cell's nucleus, which is a mix of genes from your father and mother, all of your mitochondrial DNA comes from your mother. -
Endoplasmic Reticulum
No. The endoplasmic reticulum is involved in the folding and movement of proteins in the cell. -
Chloroplast
No. Chloroplasts contain chlorophyll, which is used in photosynthesis. -
Ribosome
No. Ribosomes are parts of the cell that assemble proteins.
