# NCERT Solutions For Class 6 Social Science Geography Chapter 3 - Motions of the Earth

## NCERT Book Solutions Class 6 Chapter 3

The Earth has two types of motions, which lead to seasons and day-night patterns. These motions are â€“ rotation around its own axis and revolution around the Sun.Â Rotation means the movement of the earth on its axis. It rotates from the west towards the east.Â Revolution means the movement of the Earth around the Sun in a fixed path or orbit. This movement causes seasonal variations in different parts of the Earth. Students can go through ourÂ NCERT Solutions of Class 6 Social Science Geography Chapter 3, which is neatly arranged for your convenience.Â The questions provided in the NCERT textbook are solved in an elaborate and step-by-step manner here.

## NCERT Solutions for Class 6 Geography Chapter 3 â€“ Motions of the Earth

1. Answer the following questions briefly.

(a) What is the angle of inclination of the earthâ€™s axis with its orbital plane?

(b) Define rotation and revolution.

(c) What is a leap year?

(d) Differentiate between the Summer and Winter Solstice.

(e) What is an equinox?

(f) Why does the Southern Hemisphere experience Winter and Summer Solstice at different times than that of the Northern Hemisphere?

(g) Why do the poles experience about six months day and six months night?

(a) The angle of inclination of the earthâ€™s axis with its orbital plane is 66Â½Â°.

(b) The movement of the earth on its axis is called rotation. The movement of the earth around the sun in a fixed path or an orbit is called Revolution.

(c) Every fourth year, February has 29 days instead of 28 days. Such a year with 366 days is called a leap year.

(d) Summer Solsticeâ€“ When the Southern hemisphere experiences the winter season and it is summer in the northern hemisphere. At that point in time, the position of the earth on 21st June is called the Summer Solstice.

Winter Solsticeâ€“ When the Southern hemisphere experiences the summer season and the reverse occurs at the Northern hemisphere. At that point in time, the position of the earth on 22nd December is called the Winter Solstice.

(e) On 21st March and September 23rd, direct rays of the sun fall on the equator. At this position, neither of the poles is tilted towards the sun. Therefore, the whole earth experiences equal days and equal nights. This is called an equinox.

(f) The Earth is always revolving and it is divided into two hemispheres. The part of the earth which faces the sun experiences summer and the part away from the sun experiences winter. Therefore, Southern Hemisphere experience Winter and Summer Solstice at different times than that of the Northern Hemisphere.

(g) The Poles experience 6 months of day and six months of nights due to the inclination of the earth on its own axis. This inclination keeps one pole towards the sun and another pole away from the sun for 6 months each. This is the reason behind this condition.

(a) The movement of the earth around the sun is known as

(i) Rotation (ii) Revolution (iii) Inclination

(b) Direct rays of the sun fall on the equator on

(i) 21 March (ii) 21 June (iii) 22 December

(c) Christmas is celebrated in summer in

(i) Japan (ii) India (iii) Australia

(d) Cycle of the seasons is caused due to

(i) Rotation (ii) Revolution (iii) Gravitation

1. (ii) Revolution
2. (i) 21 March
3. (iii) Australia
4. (ii) Revolution

3. Fill in the blanks.

(a) A leap year has _______________ number of days.

(b) The daily motion of the earth is _______________.

(c) The earth travels around the sun in ______________ orbit.

(d) The sunâ€™s rays fall vertically on the Tropic of ___________ on 21st June.

(e) Days are shorter during ___________ season.

(a) A leap year has 366 number of days.

(b) The daily motion of the earth is rotation.

(c) The earth travels around the sun in anÂ elliptical orbit.

(d) The sunâ€™s rays fall vertically on the Tropic of Cancer on 21st June.

(e) Days are shorter during winter season.
