1.
Where are the planets located?
Correct Answer
B. The inner and outer solar system
Explanation
The correct answer is the inner and outer solar system. Planets are located within the solar system, which consists of the inner and outer regions. The inner solar system includes the planets that are closer to the Sun, such as Mercury, Venus, Earth, and Mars. The outer solar system includes the gas giants like Jupiter and Saturn, as well as the ice giants like Uranus and Neptune. So, the planets are distributed throughout the inner and outer regions of the solar system.
2.
Pluto is a planet.
Correct Answer
B. False
Explanation
Pluto is a dwarf planet.
3.
What is the hottest planet?
Correct Answer
C. Venus
Explanation
Venus is the correct answer because it is the hottest planet in our solar system. Despite not being the closest planet to the Sun, Venus has a thick atmosphere composed mainly of carbon dioxide, which creates a greenhouse effect trapping heat and causing extreme temperatures. The surface temperature on Venus can reach up to 900 degrees Fahrenheit (475 degrees Celsius), making it hotter than Mercury, which is closer to the Sun.
4.
Mercury is our first planet.
Correct Answer
A. True
Explanation
The statement "Mercury is our first planet" is correct because Mercury is the closest planet to the Sun in our solar system. It orbits the Sun before any other planet, making it the first planet in terms of its position from the Sun.
5.
Earth is called the Blue Planet.
Correct Answer
A. True
Explanation
The Earth is called the Blue Planet because it is mostly covered with water.
6.
We have how many moons?
Correct Answer
C. 1
Explanation
The question is asking for the number of moons we have. The correct answer is 1, indicating that we have only one moon.
7.
Our planets orbit what?
Correct Answer
A. Sun
Explanation
The planets in our solar system orbit around the sun. The sun is at the center of our solar system and exerts a gravitational pull on the planets, causing them to revolve around it. This is known as the heliocentric model, which states that the sun is the central body around which the planets orbit. The moon and clouds are not central bodies and do not have enough mass to exert a gravitational pull significant enough to cause the planets to orbit them.
8.
Jupiter is the largest planet.
Correct Answer
A. True
Explanation
Jupiter is the largest planet in our solar system. It has a diameter of about 86,881 miles, which is more than 11 times the diameter of Earth. Its massive size is due to its composition, primarily consisting of hydrogen and helium gases. Jupiter's immense gravity also contributes to its size, allowing it to attract and hold onto a large amount of gas and other materials. Its size and composition make Jupiter stand out as the largest planet among all the others in our solar system.
9.
What do we use to look at something in the distance?
Correct Answer
B. Telescope
Explanation
A telescope is used to look at something in the distance. It is a device that helps us observe distant objects by collecting and magnifying light. Unlike a microscope, which is used to view small objects up close, a telescope is designed to focus on objects that are far away, such as stars, planets, and galaxies. A magnifying glass, on the other hand, is used to enlarge the size of an object when it is held close to the eye, but it is not specifically designed for viewing objects in the distance.
10.
What is the person called that explores in space?
Correct Answer
B. Astronaut
Explanation
An astronaut is the correct answer because they are the individuals who explore and travel in space. They undergo rigorous training and are equipped with the necessary knowledge and skills to conduct scientific research, operate spacecraft, and perform extravehicular activities. Archeologists study human history through the excavation of artifacts, while teachers educate students in various subjects. Therefore, astronaut is the most appropriate term for someone who explores in space.
