A student creates two models to demonstrate phases of the Moon. The models are shown.
Two diagrams show Earth, the Sun, and the Moon. In the first diagram, Earth is in between the Sun and the Moon. In the second diagram, the Moon is in between Earth and the Sun.
Which moon phases can the models be used to demonstrate?
A.
Model 1 can be used to demonstrate a full moon, and Model 2 can be used to demonstrate a new moon.
B.
Model 1 can be used to demonstrate a new moon, and Model 2 can be used to demonstrate a third quarter moon.
C.
Model 1 can be used to demonstrate a full moon, and Model 2 can be used to demonstrate a waning crescent moon.
D.
Model 1 can be used to demonstrate a first quarter moon, and Model 2 can be used to demonstrate a waxing gibbous moon.
A.
Model 1 can be used to demonstrate a full moon, and Model 2 can be used to demonstrate a new moon.
The correct answer is D. Model 1 can be used to demonstrate a first quarter moon, and Model 2 can be used to demonstrate a waxing gibbous moon.
To determine which moon phases can be demonstrated by the given models, we need to understand the positions of the Earth, Sun, and Moon in each diagram.
In model 1, Earth is shown between the Sun and the Moon. This configuration represents a full moon. A full moon occurs when the Earth is positioned directly between the Sun and the Moon, with the Moon fully illuminated from our perspective on Earth.
In model 2, the Moon is shown between Earth and the Sun. This configuration represents a new moon. A new moon occurs when the Moon is positioned directly between the Earth and the Sun. In this position, the illuminated side of the Moon is facing away from Earth, making it appear completely dark.
So, based on the given models:
- Model 1 can be used to demonstrate a full moon.
- Model 2 can be used to demonstrate a new moon.
Therefore, the correct answer is A: Model 1 can be used to demonstrate a full moon, and Model 2 can be used to demonstrate a new moon.
