What is the closest planet to the sun?
Correct Answer
B. Mercury
Explanation
Mercury is the closest planet to the sun. It orbits the sun at an average distance of about 36 million miles. Its proximity to the sun allows it to have extremely high temperatures, reaching up to 800 degrees Fahrenheit during the day. Mercury is also the smallest planet in our solar system. Its close proximity to the sun makes it difficult to observe from Earth, and it can only be seen during certain times of the year and under specific conditions.

Select the three correct statements about Rotation and Revolution
Correct Answer(s)
B. Rotation is a spinning motion; it takes the earth 24 hours (1 day & 1 night) to Rotate
C. Revolution is an object moving in a circular motion around another object
D. It takes the Earth 365 days (1 year) to revolve around the sun; it takes the moon 28 days (1 month) to revolve around the Earth
Explanation
The given answer correctly states that rotation is a spinning motion and it takes the Earth 24 hours to rotate. It also correctly states that revolution is an object moving in a circular motion around another object. Additionally, it mentions that it takes the Earth 365 days to revolve around the sun and the moon takes 28 days to revolve around the Earth. These statements accurately describe the concepts of rotation and revolution.
3.
True or False: Aristotle and Ptolemy believed the Earth was at the center of the universe; Galileo and Copernicus believed the Sun was at the center of the universe.
Correct Answer
A. True
Explanation
Aristotle and Ptolemy were ancient Greek philosophers who believed in geocentrism, the idea that the Earth was at the center of the universe. On the other hand, Galileo and Copernicus were astronomers during the scientific revolution who supported heliocentrism, the theory that the Sun was at the center of the universe. Therefore, the statement is true as it accurately reflects the beliefs of these historical figures.
4.
Which one is NOT a phase of the moon?
Correct Answer
B. Cresent Moon

5.
Which feature is unique to the Earth?
Correct Answer
B. There's life on the planet
Explanation
The feature that is unique to Earth is the presence of life on the planet. While other planets may have rocky surfaces and atmospheres, Earth is the only known planet to support a wide variety of life forms. The existence of life on Earth is what sets it apart from other celestial bodies in our solar system and beyond.
6.
What's the name of our galaxy?
Correct Answer
C. The Milky Way

9.
Select the characteristics of the Moon (choose all that are correct).
Correct Answer(s)
A. The Moon is a satellite that revolves around the Earth
B. The Moon does not produce its own light
C. The moon is 1/4 the size of the Earth
D. There is no water on the Moon
E. The temperature on the Moon can get very hot and very cold at times
Explanation
The Moon is a satellite that revolves around the Earth, which means it orbits the Earth. It does not produce its own light but reflects the light of the Sun, which is why we see different phases of the Moon. The Moon is approximately 1/4 the size of the Earth, making it much smaller in comparison. There is no water on the Moon, as it has a very thin atmosphere and low gravity. The temperature on the Moon can vary greatly, reaching extremely hot temperatures during the day and extremely cold temperatures at night due to its lack of atmosphere to regulate heat.
10.

F. 110 times the size of the Earth
G. Made of Gas and Helium
Explanation
The Sun is an averaged-sized yellow star, which means it is not the largest star in the universe. It is 4.6 billion years old and 110 times the size of the Earth. It is made of gas and helium, not gasoline and moldy cheese.
