Why does the moon move through the sky?
Correct Answer
B. Because of the Earth's rotation
Explanation
The moon moves through the sky because of the Earth's rotation. As the Earth spins on its axis, it creates the illusion of the moon moving across the sky. The moon itself is not actually moving, but rather appears to be moving due to the Earth's rotation. This rotation causes the moon to rise in the east and set in the west, just like the sun and other celestial bodies.
2.
What is the moon phase shown below
Correct Answer
D. Full Moon
Explanation
The moon phase shown in the image is a full moon. A full moon occurs when the moon is on the opposite side of the Earth from the Sun, with its entire illuminated side facing Earth. This is the brightest phase of the moon, where it appears as a complete circle in the night sky.
3.
Which letter represents a new moon (make sure to look at the direction that the sun is coming from).
Correct Answer
A. T
Explanation
The letter T represents a new moon. A new moon occurs when the moon is positioned between the Earth and the Sun, with the side of the moon that is facing the Earth in darkness. In the given options, the letter T is the only one that is facing towards the left, indicating that the sun is coming from the right side. This aligns with the direction the sun should be coming from for a new moon.
4.
Which letter represents a first quarter moon (make sure to look at the direction that the sun is coming from)?
Correct Answer
D. Q
Explanation
The letter Q represents a first quarter moon. In the question, it is mentioned to look at the direction that the sun is coming from. During a first quarter moon, the sun is coming from the right side, and the moon appears as a half-circle with the right side illuminated. Among the given options, only the letter Q is a half-circle with the right side illuminated, indicating a first quarter moon.
5.
Which letter represents a third quarter moon (make sure to look at the direction that the sun is coming from)?
Correct Answer
C. S
Explanation
The letter "S" represents a third quarter moon. In this phase, the moon is illuminated on the left side, while the right side is in shadow. The sun is coming from the right side, illuminating the left side of the moon.
6.
What is the order of the objects for a solar eclipse?
Correct Answer
A. Sun, Moon, Earth
Explanation
During a solar eclipse, the order of the objects is Sun, Moon, Earth. This is because a solar eclipse occurs when the Moon passes between the Sun and the Earth, blocking the sunlight and casting a shadow on the Earth. Therefore, the Sun is first, followed by the Moon, and then the Earth. The option "Sun, Moon, Earth" correctly represents this sequence.
7.
What is the order of the objects for a lunar eclipse?
Correct Answer
C. Sun, Earth, Moon
Explanation
During a lunar eclipse, the order of the objects is Sun, Earth, Moon. This is because a lunar eclipse occurs when the Earth comes between the Sun and the Moon, casting a shadow on the Moon. The Sun's light is blocked by the Earth, causing the Moon to appear dark or reddish. Therefore, the correct order is Sun, Earth, Moon.
8.
A solar eclipse is when the
Correct Answer
C. Shadow of the moon falls on the Earth
Explanation
During a solar eclipse, the shadow of the moon falls on the Earth. This occurs when the moon passes between the Earth and the sun, blocking the sunlight and casting a shadow on the Earth's surface. The moon's shadow is responsible for obscuring the sun and causing the temporary darkness experienced during a solar eclipse.
9.
A lunar eclipse is when the
Correct Answer
D. Shadow of the Earth falls on the Moon
Explanation
During a lunar eclipse, the Earth comes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon. This occurs when the Moon is in the opposite direction of the Sun, and the Earth blocks the sunlight from reaching the Moon's surface. As a result, the Moon appears to darken and may even take on a reddish hue due to the Earth's atmosphere bending some of the sunlight around the Earth and onto the Moon. Therefore, the correct answer is that the shadow of the Earth falls on the Moon during a lunar eclipse.
10.
What is this an image of?
Correct Answer
C. A solar eclipse
Explanation
This image is a depiction of a solar eclipse. A solar eclipse occurs when the moon passes between the sun and the Earth, blocking the sunlight and casting a shadow on the Earth's surface. In the image, the moon can be seen partially covering the sun, creating a stunning visual effect.
11.
What is this a picture of?
Correct Answer
B. A lunar eclipse
Explanation
This picture depicts a lunar eclipse, which occurs when the Earth is positioned between the Sun and the Moon, causing the Moon to pass through the Earth's shadow. During a lunar eclipse, the Moon appears to darken and may take on a reddish hue due to the scattering of sunlight by the Earth's atmosphere. This distinguishes it from a solar eclipse, where the Moon passes between the Sun and the Earth, blocking the Sun's light. A harvest moon refers to the full moon that occurs closest to the autumnal equinox, and a new moon is when the Moon is not visible from Earth.
12.
What are tidal changes caused by?
Correct Answer
A. The moon revolving around the Earth
Explanation
Tidal changes are caused by the gravitational pull of the moon on the Earth's oceans. As the moon revolves around the Earth, its gravitational force creates a bulge of water on the side of the Earth closest to the moon, causing a high tide. On the opposite side, there is also a high tide due to the centrifugal force caused by the Earth and moon's rotation. This creates two high tides and two low tides every day. Therefore, the correct answer is "The moon revolving around the Earth."
13.
We have tides mostly because of
Correct Answer
B. The moon's gravitational pull
Explanation
The moon's gravitational pull is the main reason for tides. The moon's gravitational force attracts the water on Earth, causing a bulge on the side facing the moon and a corresponding bulge on the opposite side. As the Earth rotates, different locations experience high and low tides. The sun's gravitational pull also contributes to tides, but its effect is less significant compared to the moon. The uneven heating of the Earth and winds do not directly cause tides, although they can indirectly affect tidal patterns.
14.
How many high tides are there a day?
Correct Answer
B. 2
Explanation
There are typically two high tides in a day. This is because the gravitational pull of the moon causes the ocean waters to bulge on the side of the Earth that is facing the moon and on the opposite side as well. As the Earth rotates, different locations experience high tides at different times. Therefore, there are two high tides and two low tides in a 24-hour period.
15.
Do tides come at the same time each day?
Correct Answer
D. No, but you can predict them
Explanation
Tides do not come at the same time each day. However, they can be predicted based on the gravitational pull of the moon and the sun. The timing and height of tides vary depending on factors such as the location, the alignment of the sun, moon, and Earth, and the shape of the coastline. By using tidal charts and data, it is possible to forecast when high and low tides will occur in a specific area.
