Very Short Answer Questions: 1 Mark

1. Fill in the blanks:

(i) Revolution is the moment of the earth around the _____.

Ans: Sun - Revolution is the movement of the earth around the Sun in a fixed route or orbit.

(ii) Rotation is the moment of earth on its ______.

Ans: Axis - The Earth revolves at a speed of around 1,600 kilometres (1,000 miles) per hour around its axis. It travels at a speed of 107,800 kilometres (67,000 miles) per hour around the Sun.

(iii) The earth completes one revolution of the Sun in ______ days.

Ans: 365 - In 365 days, 5 hours, 59 minutes, and 16 seconds, the Earth revolves around the Sun. A year is the length of time it takes for a planet to orbit the Sun.

(iv) The earth takes ____hours to rotate around its axis.

Ans: 24 hours - In relation to the Sun, Earth rotates once every 24 hours, 56 minutes, and 4 seconds, but once every 23 hours, 56 minutes, and 4 seconds in relation to other, distant stars.

2. State true and false.

(i) The Sun revolves around the earth.

Ans: False

(ii) There are nine planets in our solar system.

Ans: False

(iii) Poles experience 6 months-long nights and 6 months-long days.

Ans: True

(iv) Direct rays of the Sun fall on the equator on 21 June.

Ans: False

3. Match the following:-

i. Equinox	25 December
ii. Christmas Day	366 days
iii. Leap year	Winter
iv. Short days	Equal day and night

Ans:

i. Equal Day and Night - Equinox is one of the two times during the year when the Sun is directly above the Equator and day and night are of equal length; it is also one of the two points in the sky where the ecliptic (the Sun's annual journey) and the celestial equator connect.

ii. 25 December - Christmas is observed on December 25th.

iv. Winter - The Sun's rays impact the Earth at a shallow angle during the winter. The Sun's beams are more widely dispersed, reducing the quantity of energy that reaches any specific location. The Earth can't warm up because of the long nights and short days.

a) Elliptical

b) Semi circle

c) Hyperbolic

d) Circular

Ans: Elliptical

Short Answer Questions

6. What will happen if the earth stops rotating?

Ans: Life on the planet will be impossible if the earth stops revolving.

7. What is rotation?

Ans: Rotation is the movement of the earth on its axis. The rotation of the Earth on its axis takes 24 hours.

8. Why the earth faces nights and day?

Ans: The rays of the Sun fall at different times on the planet due to the rotation of the earth, resulting in day and night.

9. What is the reason for the season change?

Ans: As the earth circles around the Sun, its location varies over time, resulting in the change of seasons.

10. In the Northern hemisphere, which day is considered as the shortest day?

Ans: The shortest day in the Northern Hemisphere is December 22nd.

Short Answer Question II 3 Mark

11. What is a leap year? Why does it take place?

Ans: On average, the Earth travels around the Sun in 365 14 days. One year is defined as 365 days. The remaining 6 hours, multiplied by 4, equals 24 hours, or one day. The month of February has an extra 29th day, and the year has 366 days, making it a leap year.

12. When do the longest day and the shortest night take place?

Ans: The Northern Hemisphere is tilted towards the Sun on June 21st, and hence the Sun's rays fall directly on the Tropic of Cancer. This raises the temperature in that area. Because the sun shines on a large chunk of the northern hemisphere, it is summer in those areas. On June 21, the longest day and the shortest night occur.

13. When do the days get shorter and why?

Ans: During the winter, the days are shorter. The evenings are longer than the days throughout the winter season. The days are longer than the nights throughout the summer.

14. Define the motion of the earth.

Ans: Rotation is the earth's daily motion. There are two types of motion on Earth: rotation and revolution. The motion of the earth on its axis is known as rotation. The world rotates once every 24 hours, which is why the days and nights, as well as the seasons, change.

15. How does the change of the season take place?

Ans: The revolution is what causes the seasons to cycle. The shift in the earth's location around the Sun causes the seasons. The earth follows its own orbit or course around the Sun. The four seasons, summer, winter, autumn, and spring are caused by the earth's movement and its axis tilt in a set direction.

16. What is the difference between the Winter Solstice and Summer Solstice?

Ans: The position of the earth during the Summer Solstice is when the Sun's rays fall directly on the Tropic of Cancer. The earth's position at the Winter Solstice is when the Sun's rays fall directly on the Tropic of Capricorn. The North Pole is inclined towards the Sun during the summer solstice and away from the Sun during the winter solstice.

The light from the Sun falls on the majority of the Northern Hemisphere during the summer solstice, and it is summer there when the days are longer than the nights. The majority of the Southern Hemisphere receives sunlight during the winter solstice, while it is winter in the Northern Hemisphere, and the nights are longer than the days.

17. Why is the Winter and Summer Solstice experienced at different times in the Southern and Northern Hemispheres?

Ans: The summer solstice occurs when the North Pole tilts towards the Sun in the Northern Hemisphere. The South Pole is tilted away from the Sun in this situation, causing the Southern Hemisphere to experience winter solstice. When the South Pole is tilted towards the Sun, the Summer Solstice occurs, and when the North Pole is inclined away from the Sun, the Winter Solstice occurs. This explains why the winter and summer solstices occur at different times in the Southern and Northern Hemispheres.

18. Where do six months-long nights and days take place and why?

Ans: For around six months, the tilt of the earth on its axis causes each of the poles to be slanted either towards or away from the Sun. The poles endure around six months of night and six months of day due to this tilt. There is continuous daylight for six months when the North Pole is turned towards the Sun. The South Pole is tilted away from the Sun at this time, and it is night for the duration. When the South Pole is turned towards the Sun, it receives continuous daylight for six months.

19. Explain the equinox.

Ans: The equinox is the point on Earth where the Sun's rays fall squarely on the equator. The South Pole and the North Pole are not tilted toward the Sun in this situation. The days and nights are the same all throughout the world. This occurs on March 21st and September 23rd. On the equinox, all of the earth's nights and days are equal. The Sun receives an equal amount of sunrays in the Northern and Southern Hemispheres on this day.

20. What are rotation and revolution?

Ans: The rotation and revolution of the Earth are two different motions. Rotation is the movement of the earth on its axis. The Earth follows a set orbit or path around the Sun. Revolution is the name given to this movement. The earth takes approximately 24 hours to complete one rotation around its axis. This is known as Earth Day. The earth revolves around the Sun in about 365 days. The earth's revolution around the Sun is known as the revolution of the earth around the Sun.

3. What will students learn in Class 6 Social Science Geography Chapter 3?

Class 6 Social Science Geography Motions of the Earth Chapter 3 deals with the movement of the Earth around its own axis and also around the Sun. This chapter further explains the phenomena occurring due to rotation and revolution of the earth, which includes Summer Solstice, Winter Solstice, and Equinox. Students are also made familiar with terms like circle of illumination, orbital plane, leap year, and elliptical orbit.

4. What is an equinox present in Chapter 3 of Important Questions for Class 6 Geography?

The days of 21st March and September 23rd each year experience an equinox, meaning the whole earth experiences equal days and equal nights. It is the phenomenon when direct rays of the Sun fall on the equator, implying that neither of the poles is tilted towards the Sun.

5. What are the movements of the Earth as discussed in Class 6 Geography Chapter 3?

Earth has two main types of motions, called rotation and revolution. Rotation is when the Earth rotates on its axis. The earth takes 24 hours to finish one rotation, which we call a day. Revolution is the movement of the Earth around the Sun on a fixed path or orbit. The earth takes 365 days to finish one revolution, which we call a year.
