1.
What is the study of stars called?
Correct Answer
B. Astronomy
Explanation
Astronomy is the correct answer because it is the scientific study of celestial objects, such as stars, planets, galaxies, and other phenomena that exist outside Earth's atmosphere. It involves observing, analyzing, and understanding the physical and chemical properties, as well as the motion and evolution, of these celestial bodies. Spacelogy, Nasaonomy, and Astrology are not recognized scientific terms and do not refer specifically to the study of stars.
2.
Shooting stars are rapidly moving meteors that are burning up.
Correct Answer
A. True
Explanation
Shooting stars are indeed rapidly moving meteors that burn up as they enter the Earth's atmosphere. These meteors are often small particles or fragments of debris from space, such as comets or asteroids. As they travel through the atmosphere, the intense friction causes them to heat up and glow, creating the appearance of a streak of light in the sky. This phenomenon is commonly known as a shooting star or a meteor. Therefore, the statement "Shooting stars are rapidly moving meteors that are burning up" is true.
3.

5.
If a star is red, is it a hot or cold star according to Astronomers?
Correct Answer
D. Very cold.
Explanation
According to astronomers, if a star is red, it indicates that the star is very cold. The color of a star is determined by its temperature, with red stars being the coolest.
6.
What are stars made of?
Correct Answer
B. Gases
Explanation
Stars are made primarily of gases. The immense heat and pressure within a star's core cause hydrogen atoms to fuse together, creating helium and releasing a tremendous amount of energy in the process. This process, known as nuclear fusion, powers the star and produces light and heat. Other gases, such as helium, carbon, and oxygen, can also be found in varying amounts within a star. While stars may contain small amounts of other materials, such as dust and metals, the dominant component is gas.
7.
Which ones are types of stars?
Correct Answer(s)
A. Super Giants
C. Main Sequence
D. Giants
F. Dwarfs
Explanation
The given answer correctly identifies the types of stars. Super Giants, Main Sequence, Giants, and Dwarfs are all categories of stars based on their size, brightness, and stage of evolution. Comets and Little Sequence, on the other hand, are not types of stars.
