How many days those Moon take to orbit the Earth?
Correct Answer
C. 28days
Explanation
The correct answer is 28 days because the Moon takes approximately 27.3 days to complete one orbit around the Earth. This is known as its sidereal period. However, due to the Earth's rotation around the Sun, it takes an additional 2.2 days for the Moon to return to the same phase, resulting in a total of approximately 29.5 days, which is known as its synodic period. Therefore, on average, it takes about 28 days for the Moon to complete one orbit around the Earth.
2.
What is a Sun?
Correct Answer
A. A star
Explanation
A sun is a star that is at the center of a solar system and emits light and heat. It is not a planet, gas, or rock. The term "sun" is commonly used to refer to the star that is closest to Earth, which is the center of our solar system. Stars, including the sun, are massive celestial bodies that are primarily composed of hydrogen and helium gases and undergo nuclear fusion to produce energy.
3.
When is the shadow shortest?
Correct Answer
B. Noon
Explanation
The shadow is shortest during noon because that is when the sun is at its highest point in the sky. When the sun is directly overhead, the objects cast a shorter shadow because the light source is directly above them, resulting in a smaller shadow. In contrast, during morning or evening, the angle of the sun is lower, causing objects to cast longer shadows. At night or midnight, there is no sunlight, so there are no shadows.
4.
Why is there a Moon ?
Correct Answer
B. The Sun's light goes straight at the Moon and reflect to Earth
Explanation
The Moon shines because the Sun's light goes straight at the Moon and reflects back to Earth. This reflection of sunlight is what makes the Moon appear bright in the night sky.
5.
What does the other half of the Earth do when the other half is morning?
Correct Answer
D. Night
Explanation
When one half of the Earth is experiencing morning, the other half is in the opposite time zone and is experiencing night. This is due to the rotation of the Earth on its axis, which causes different parts of the planet to be exposed to sunlight at different times. Therefore, the correct answer is night.
6.
How is a shadow made?
Correct Answer
B. Because the person is blocking the light
Explanation
A shadow is made when an object blocks the path of light. In this case, the person is blocking the light, causing a shadow to be formed.
7.
What is the word that the moon turns around the earth?
Correct Answer
B. Orbit
Explanation
The word "orbit" is the correct answer because it accurately describes the motion of the moon around the earth. An orbit refers to the path that an object takes as it revolves around another object due to gravitational forces. In this case, the moon orbits around the earth, meaning it follows a curved trajectory around our planet. The word "turning" does not accurately describe this motion, and "rotates" implies a spinning motion rather than an orbital one.
8.
What is the largest in the solar system?
Correct Answer
A. Sun
Explanation
The largest object in the solar system is the Sun. It is a star that is much larger than any planet or dwarf planet. The Sun's immense size allows it to have a strong gravitational pull, which keeps all the planets and other objects in orbit around it. Additionally, the Sun's size enables it to emit vast amounts of energy through nuclear fusion, providing heat and light to the entire solar system.
9.
Which way does the sun rise?
Correct Answer
A. East
Explanation
The sun rises in the east. This is a well-known fact that can be observed by anyone who pays attention to the sunrise. The Earth rotates from west to east, causing the sun to appear to rise in the east and set in the west. This is a consistent pattern that has been observed and recorded by civilizations throughout history. Therefore, the correct answer is east.
10.
Where does the sun set at?
Correct Answer
C. West
Explanation
The sun sets in the west because of the Earth's rotation. As the Earth spins on its axis from west to east, it appears as though the sun is moving across the sky from east to west. During sunset, the sun is positioned in the western part of the sky, and as it continues to move, it eventually disappears below the horizon in the west. This phenomenon is consistent across most locations on Earth, although the exact direction of sunset may vary slightly depending on one's latitude and time of year.
