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.

Which position would the Moon be in during an eclipse of the Moon?
-
A
No. In this position, the Moon would not be in the Earth's shadow. -
B
No. In this position, the Moon would not be in the Earth's shadow. -
C
No. In this position, the Moon would not be in the Earth's shadow. -
D
Yes. In this position, the Moon could be in the Earth's shadow. It does not always pass through the shadow, so we don't have an eclipse every month, but when it does, it will be in this position.

These layers have not been overturned or folded. Based on that, which layer is the oldest?
-
A
No. A is on top, which means the other layers had to be there before it could be deposited. A is younger than B and C. -
B
No. By the law of Superposition, layer C had to be in place before B could form on top of it. Layer B is older than A, but younger than C. -
C
Yes! As the bottom layer, the Law of Superposition tells us that it is older than layers A and B. This layer had to be in place before A and B could form on top of it.. -
D
No. Layer D is actually a pile of rock fragments, mostly from layer A. These fragments are the result of weathering and erosion of layers A, B, and C. D is the youngest deposit at this location.

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.

I found this caterpillar in my garden. Based on its bright colors, I decided not to pick it up. Why would it be so brightly colored?
-
To help it hide in flowers.
No. Its pattern of colors would not blend in with a flower. -
To warn away predators.
Yes! Many brightly colored animals are toxic or dangerous. They use their bright colors to warn potential predators that they taste bad, sting, or have some other characteristic that a predator would want to avoid.This is the caterpillar of a Hooded Owlet Moth. They eat the wild asters in our area, which gives them a very bitter taste that birds don't like.
-
To attract a mate.
No. Caterpillars do not mate. They must go through metamorphosis into a butterfly or moth before they can mate. -
To help it find food.
No. Most caterpillars eat plants, and bright colors would not help with that..
