Show why Australia gets more UV light than Brazil by
modeling how UV light waves travel through the
atmosphere above each place.
Complete the model by extending each UV light
wave. Use the key to show how the light wave
Interacts with the molecules in the air. If the light
hits a material in the atmosphere, show what
happens to the UV light.
• Use a yellow highlighter to trace the path of energy
• Annotate your model to help show why Australia
gets more UV light than Brazil.
• Tips: Some materials will not be hit by a UV light
wave in your model.

Iknow the answer to 13 is b and 14 is d. i just need to know why the correct answers are correct

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.
