All questions of The Earth and Its Movements for Primary 6 Exam

How does the tilt of the Earth's axis affect the seasons?
  • a)
    It leads to the Moon's phases
  • b)
    It is responsible for the Earth's distance from the Sun
  • c)
    It has no effect on the seasons
  • d)
    It causes varying sunlight intensity and duration
Correct answer is option 'D'. Can you explain this answer?

Kds Coaching answered
The tilt of the Earth's axis, which is approximately 23.5 degrees, plays a crucial role in the changing seasons. During summer in the Northern Hemisphere, this tilt causes the Sun's rays to strike more directly and for longer periods, leading to warmer temperatures. In contrast, during winter, the Northern Hemisphere is tilted away from the Sun, resulting in less direct sunlight and shorter days, causing cooler temperatures. This axial tilt is the primary reason for the seasonal variations experienced on Earth.

What is the significance of solstices and equinoxes in understanding Earth's movement?
  • a)
    They mark the beginning of summer and winter
  • b)
    They represent equal day and night
  • c)
    They are only significant for the Northern Hemisphere
  • d)
    They indicate when the Earth is closest to the Sun
Correct answer is option 'B'. Can you explain this answer?

Kds Coaching answered
Solstices and equinoxes are key markers for understanding Earth's movement and its axial tilt. The summer solstice, occurring around June 21, is the longest day of the year in the Northern Hemisphere, while the winter solstice, around December 22, is the shortest day. Equinoxes, occurring around March 21 and September 23, are when day and night are approximately equal in length. These events highlight the effects of Earth's tilt and its orbit around the Sun, significantly influencing climatic patterns and seasonal changes.

How long does it take for the Earth to complete one revolution around the Sun?
  • a)
    30 days
  • b)
    365 days and 6 hours
  • c)
    365 days
  • d)
    24 hours
Correct answer is option 'B'. Can you explain this answer?

Kds Coaching answered
The Earth takes about 365 days and 6 hours to complete one full revolution around the Sun. This period defines the length of a year. To account for the extra six hours, we add a leap day every four years, resulting in a leap year with 366 days. This adjustment helps keep our calendar aligned with the Earth’s position in its orbit.

During which event do day and night last approximately 12 hours each?
  • a)
    Winter solstice
  • b)
    Summer solstice
  • c)
    Autumn equinox
  • d)
    Spring equinox
Correct answer is option 'D'. Can you explain this answer?

Kds Coaching answered
The spring equinox, which occurs around March 21, is the event when day and night are approximately equal in length, lasting about 12 hours each. This balance occurs because the Sun is positioned directly over the equator. The same phenomenon occurs during the autumn equinox around September 23. These equinoxes mark the transitions between the seasons and are significant in many cultures.

What is the apparent motion of celestial objects caused by?
  • a)
    The revolution of the Earth
  • b)
    The gravitational pull of the Moon
  • c)
    The rotation of the Earth
  • d)
    The distance of celestial objects
Correct answer is option 'C'. Can you explain this answer?

Kds Coaching answered
The apparent motion of celestial objects, such as the Sun, Moon, and stars, across the sky is primarily caused by the rotation of the Earth on its axis. As the Earth spins from west to east, celestial bodies appear to move from east to west. This phenomenon is an optical illusion resulting from our perspective on the rotating planet.

Which of the following describes a lunar eclipse?
  • a)
    The Moon appears bright and full
  • b)
    The Moon moves between the Earth and the Sun
  • c)
    The Moon is in its new phase
  • d)
    The Earth blocks sunlight from reaching the Moon
Correct answer is option 'D'. Can you explain this answer?

Kds Coaching answered
A lunar eclipse happens when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. During a total lunar eclipse, the Moon can take on a reddish hue, often referred to as a "blood moon," due to the scattering of sunlight through the Earth's atmosphere. This event is safe to observe with the naked eye and can be seen from anywhere on the nighttime side of the Earth.

They are often used to predict weather patterns, guide agricultural practices, inform religious observances, and serve as a foundation for calendars and timekeeping. Many cultures have developed intricate systems of knowledge based on the patterns of the stars and planets, reflecting their deep connection to the cosmos.

What is a lunar eclipse, and how does it occur?
  • a)
    Earth blocks sunlight from reaching the Moon.
  • b)
    The Moon rotates around the Earth.
  • c)
    The Sun blocks light from reaching both Earth and Moon.
  • d)
    The Moon blocks sunlight from reaching Earth.
Correct answer is option 'A'. Can you explain this answer?

Kds Coaching answered
A lunar eclipse occurs when the Earth positions itself directly between the Sun and the Moon, preventing sunlight from illuminating the Moon. This results in the Earth's shadow being cast on the Moon, which can turn it a reddish color during a total lunar eclipse. Unlike solar eclipses, lunar eclipses are safe to view without any protection and can be observed from anywhere on the night side of Earth.

What causes the cycle of day and night on Earth?
  • a)
    The Earth's rotation on its axis
  • b)
    The Earth's revolution around the Sun
  • c)
    The tilt of the Earth's axis
  • d)
    The Moon's orbit around the Earth
Correct answer is option 'A'. Can you explain this answer?

Kds Coaching answered
The cycle of day and night is caused by the Earth's rotation on its axis, which takes approximately 24 hours to complete. As the Earth spins, different parts of its surface move into and out of sunlight, resulting in the alternating periods of day and night. This motion is why we see the Sun rise in the east and set in the west, creating a predictable daily rhythm that affects all life on Earth.

Why is it unsafe to look directly at a solar eclipse?
  • a)
    It may cause confusion about the time of day.
  • b)
    It can cause permanent blindness.
  • c)
    It affects the gravity on Earth.
  • d)
    It alters the color of the sky.
Correct answer is option 'B'. Can you explain this answer?

Kds Coaching answered
Looking directly at a solar eclipse can cause permanent damage to the eyes, including blindness, because the Sun's intense light is still harmful even when partially obscured by the Moon. Specialized solar viewing glasses or indirect viewing methods, such as pinhole projectors, are recommended to safely observe a solar eclipse. This safety measure is crucial for protecting eyesight during this spectacular event.

What effect does the tilt of the Earth's axis have on the seasons?
  • a)
    It leads to variations in sunlight intensity and duration.
  • b)
    It prevents solar eclipses from occurring.
  • c)
    It causes the Earth to orbit the Sun more quickly.
  • d)
    It makes the Moon appear larger in the sky.
Correct answer is option 'A'. Can you explain this answer?

Kds Coaching answered
The tilt of the Earth's axis, which is approximately 23.5 degrees, results in varying angles of sunlight received at different times of the year, leading to seasonal changes. When the Northern Hemisphere tilts toward the Sun, it experiences summer, with longer days and more intense sunlight. Conversely, when it tilts away, winter occurs, resulting in shorter days and less intense sunlight. The Southern Hemisphere experiences opposite seasons.

What phenomenon occurs when the Moon blocks sunlight from reaching parts of the Earth?
  • a)
    Equinox
  • b)
    Solstice
  • c)
    Solar eclipse
  • d)
    Lunar eclipse
Correct answer is option 'C'. Can you explain this answer?

Kds Coaching answered
A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking sunlight from reaching certain areas on Earth. This can result in a total solar eclipse, where the Sun is completely obscured, or a partial solar eclipse, where only part of the Sun is hidden. The apparent size of the Moon allows it to cover the Sun, despite being much smaller, due to its proximity to Earth.

What occurs during a solar eclipse?
  • a)
    The Earth casts a shadow on the Moon
  • b)
    The Earth moves between the Sun and the stars
  • c)
    The Moon blocks sunlight from reaching the Earth
  • d)
    The Sun moves in front of the stars
Correct answer is option 'C'. Can you explain this answer?

Kds Coaching answered
A solar eclipse occurs when the Moon comes directly between the Earth and the Sun, blocking sunlight from reaching certain areas on Earth. This can result in a total solar eclipse, where the Moon completely covers the Sun, or a partial solar eclipse, where only part of the Sun is obscured. Despite the Moon being much smaller than the Sun, its proximity to Earth allows it to effectively block the Sun's light during these events.

What phenomenon causes the cycle of day and night on Earth?
  • a)
    The Sun's movement through space
  • b)
    The Moon's phases
  • c)
    The Earth's rotation on its axis
  • d)
    The Earth's revolution around the Sun
Correct answer is option 'C'. Can you explain this answer?

Kds Coaching answered
The cycle of day and night on Earth is caused by the Earth's rotation on its axis, which takes about 24 hours to complete. As the Earth spins, different parts of its surface move in and out of sunlight, creating alternating periods of day and night. This rotation is counterclockwise when viewed from above the North Pole, making the Sun appear to rise in the east and set in the west.
