Worksheet Solutions: Motions of the Earth

# Motions of the Earth Class 6 Worksheet Geography Chapter 3

Q.1. State True (T) or false (F).

(i) Axis of the earth is an imaginary line about which the earth rotates.  True
(ii) Earth takes exactly 365 days to revolve around the sun. False
(iii) Day and Night on the Earth occurs due to rotation of the Earth. True
(iv) On 21st march, the Tropic of Capricorn receives direct rays of the sun as the South Pole tilts towards it. False
(v) Every fourth year, February is of 29 days instead of 28 days. True
(vi) When there is spring in the Northern Hemisphere and summer in the Southern Hemisphere. False

Q.2. What is the shape of the Earth?

Earth is spherical in shape.

Q.3. Differentiate between rotation and revolution of earth.

Q.4. When Christmas is celebrated in Australia?

Christmas is celebrated in Australia in the summer season.

Q.5. Which motion of the earth causes change in seasons?

Revolution of the earth causes change in seasons.

Q.6. Why do the poles experience about six months of day and night?

The Poles experience about six months of day and six months of night because of the tilt of the Earth on its axis. When the North Pole is tilted towards the Sun, it experiences continuous daylight for six months and when the South Pole is away from the sun, it experiences continuous

darkness for six months.

Q.7. How long does it take the earth to complete one rotation around its axis?

The earth takes about 24 hours to complete one rotation around its axis.

Q.8. Why do seasons occur?

The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels around the sun in its orbit.

Q.9. When do the sun rays fall directly on the equator?

On 21st March and September 23rd, direct rays of the sun fall on the equator.

Q.10. Why days and nights are not of equal length?

Days and nights are not equal length because of the inclined axis of the earth. As earth is tilted at an angle of 23.4°, days are longer in summers than in winters.

Q.11. What causes change in seasons?

Seasons change due to the change in the position of the earth around the sun.

Q.12.  Fill in the blanks.

(i) The earth receives light from the sun.
(ii) The earth takes about 24 hours to complete one rotation around its axis.
(iii) The period of rotation is known as the earth day.
(iv) On 23rd September, it is autumn season in the Northern Hemisphere and spring season in the Southern Hemisphere.
(v) The portion facing the sun experiences day while the other half away from the sun experiences night.
(vi) The axis of the earth makes an angle of  66½ degree with its orbital plane.
(vii) Australia lies in Southern Hemisphere. viii. The longest day and the shortest night at these places occur on 21st june.

Q.13. Why areas near the poles receive less heat?

The areas near the poles receive less heat as the rays of the sun are slanting.

## FAQs on Motions of the Earth Class 6 Worksheet Geography Chapter 3

 1. What causes the Earth's seasons to change?
Ans. The Earth's seasons change due to its axial tilt as it orbits the Sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, resulting in the four distinct seasons.
 2. How does the Earth's rotation affect day and night?
Ans. The Earth's rotation on its axis is what causes day and night. As the Earth rotates, different parts of the planet are exposed to sunlight, creating daytime, while the areas in shadow experience nighttime.
 3. What is the significance of the Earth's orbit around the Sun?
Ans. The Earth's orbit around the Sun is crucial for providing the planet with the right amount of heat and light necessary for life to thrive. This orbit also determines the length of a year and the changing seasons.
 4. How does the Earth's tilt impact the length of daylight hours?
Ans. The Earth's tilt affects the length of daylight hours by determining how much sunlight a particular region receives at different times of the year. The tilt causes the angle at which sunlight hits the Earth to vary, resulting in longer days in summer and shorter days in winter.
 5. Can the Earth's rotation speed change over time?
Ans. Yes, the Earth's rotation speed can change slightly over time due to factors such as the gravitational pull of the Moon and other celestial bodies. However, these changes are minimal and do not significantly impact the overall rotation of the Earth.
