Chapter 3 of the NCERT Class 6 Geography textbook, “Motions of the Earth,” explains the fascinating phenomena of day-night cycles and seasons, all resulting from the Earth’s rotation and revolution. The Earth spins on its axis, a movement known as rotation, and this causes our daily cycle of day and night. Meanwhile, its journey around the Sun, called revolution, takes a year and is responsible for the changing seasons we experience.
For students seeking to understand these concepts, our platform offers a range of resources, including NCERT solutions for class 6 geography. These materials, found in our NCERT books, are prepared to provide easy-to-understand answers from the NCERT textbooks for effective learning and homework assistance.
Infinity learns concise, step-by-step solutions help simplify these scientific ideas. By referring to our NCERT solutions for class 6, students will find studying geography more accessible and enjoyable, making it easier to prepare for their exams and appreciate the natural phenomena that shape our world.

Class 6 Geography Chapter 3 Motions of the Earth Questions and Answers
Motions of the Earth Exercises (Page No. 21)
1. Answer the following questions briefly.
(a) What is the angle of inclination of the Earth’s axis with its orbital planet?
Ans.
(a) The Earth’s axis isn’t straight up and down — it’s actually tilted! This tilt is super important because it affects the weather and seasons. Now, imagine a straight line that we could draw through the Earth while it travels around the Sun. The angle between the Earth’s axis and this imaginary line is what we call the angle of inclination. For our Earth, this angle is 23.5 degrees. It might seem like a small lean, but this tilt is responsible for the different climates we experience in different parts of the world!
(b) Define rotation and revolution.
Answer:
- Rotation: Have you ever spun around in a circle? That’s a bit like what the Earth does every day! When the Earth spins around on its own axis (an imaginary line going from the North Pole to the South Pole), it’s called rotation. This spinning is why we have day and night. When your side of the Earth faces the Sun, it’s bright and sunny, and when it spins away from the Sun, it gets dark, and we see the Moon and stars. It takes about 24 hours for the Earth to complete one full spin.
- Revolution: Now, while the Earth is busy spinning, it’s also traveling around the Sun. This big circular trip is called revolution. The Earth takes about 365 days, or one whole year, to go all the way around the Sun. This movement is super important because it’s why we have seasons like summer, winter, spring, and fall. Depending on where the Earth is on its path around the Sun, we get more or less sunlight, making it warmer or cooler.
(c) What is a leap year?
Answer:
- Earth takes 365¼ days to revolve around the Sun.
- As a convenience, we consider a year to consist of 365 days.
- The six hours (1/4th of 24 hours) that are ignored make one day (24 hours) over four years.
- This surplus day is added to February.
- Every fourth year, February is observed as having 29 days, and such a year (366 days) is known as a leap year.
(d) Differentiate between the Summer and Winter Solstice.
Answer:
(e) What is an equinox?
(f) Why does the Southern Hemisphere experience Winter and Summer Solstice at different times than the Northern Hemisphere?
(g) Why do the Poles experience six months day and six months night?

Summary of Class 6 Geography Chapter 3 Motions of the Earth
In this chapter, we learn about two cool ways Earth moves in space:
- Spinning on its Axis (Rotation): Earth spins like a toy top! It takes 24 hours to make one full spin. This spinning is why we have day and night – when you’re facing the Sun, it’s day, and when you’re not, it’s night.
- Orbiting the Sun (Revolution): At the same time, Earth is on a year-long trip around the Sun. This trip is why we have different seasons like summer and winter.
Because Earth is a bit tilted, not straight, we get different amounts of sunlight during the year. This tilt causes our seasons! Sometimes your part of the Earth is closer to the Sun (hot, hot, hot summer!), and half a year later, it’s further away (brrr, cold winter!).
There are also special days called equinoxes when day and night are equal, and solstices, when we have the longest or shortest day.
Oh, and a fun fact: the very top and bottom of Earth (the Poles) have six-month-long days and nights! Imagine having a six-month-long sleepover night!
So, all these motions of Earth give us our daily sunrises and sunsets, and the different seasons that make our year so interesting!
NCERT Solutions for Class 6 Social Science Geography Chapter 3 Motions of the Earth
NCERT Class 6 Social Science Geography Chapter 3 Motions of the Earth describes the Earth’s rotations and how the Earth’s dynamics interact with the rest of the universe. The rotation and revolution of the Earth are two types of motion. Once every 24 hours, the Earth rotates around its axis from west to east. About 365 1/4 days pass between Earth and the Sun. This movement is known as the revolution. In this chapter, the rotation of the Earth is explained.
Earth receives light from the Sun. This movement illuminates the Earth facing the Sun. During the day, we call it a day, while at night, we call it a night. The half of the Earth facing the Sun would always be warm and have a day all the time, while the other half would always be cold and have a night. Life on Earth would not have been possible in such conditions.
The Earth’s Revolution is also explained in the chapter Motions of the Earth. Our planet completes the revolution around the Sun by moving around it at a speed of 96000 kilometers per hour. NCERT Geography Class 6 The growing and decreasing days and nights are described in Chapter 3 of the Earth’s motion. It also clarifies the concept of the Earth’s shifting seasons, which occur every year. This chapter also contains information about Polar days and nights. The Sun shines for 24 hours on the Northern Pole throughout the summer season (March to September) in the Northern Hemisphere. This condition lasts six months at the North Pole. Similarly, the Southern Hemisphere has a summer season (September-March), resulting in six-month-long nights at the North Pole and vice versa. This chapter also covers the distinct seasons in various places that occur throughout the year.

FAQs on Class 6 Social Science Geography Chapter 3 Motions of the Earth
What is equinox Class 6 short answer?
An equinox is a special day that happens twice a year when day and night are of the same length. It occurs because the Sun is directly above the equator. This balance between day and night happens around March 21st and September 23rd.
What are comets Class 6?
Comets are like space snowballs made from ice, dust, and small rocky particles. They orbit the Sun, and as they get closer to it, they heat up and leave a trail of gas and dust behind them, creating a beautiful glowing tail in the sky.
What is rotation for Class 6?
Rotation is when the Earth spins around like a top. This spinning happens around an imaginary line called an axis. Thanks to this motion, we have day and night. It takes about 24 hours for Earth to complete one full spin.
What is orbit class 6?
An orbit is the path that Earth follows around the Sun. Imagine it like a huge circle that Earth travels around once every year. This journey around the Sun is also why we experience different seasons.
What are the 5 types of motion Class 6?
- Straight: Moving in one direction.
- Circular: Going round in a circle, like Earth's orbit around the Sun.
- Rotational: Spinning around an axis, like Earth's rotation.
- Oscillatory: Moving back and forth, like a swing.
- Random: Moving any which way, like a fly buzzing around.
What is the main motion of the earth?
The main motions of the Earth are its rotation on its axis, which gives us day and night, and its revolution around the Sun, which causes the change in seasons throughout the year.
What are the motions of the earth Class 6?
For Class 6, the motions of the Earth refer to two key movements: rotation (the Earth spinning on its axis every 24 hours) and revolution (the Earth taking a year-long journey around the Sun). These motions explain why we have days, nights, and seasons.
What is the motion of the earth geography chapter?
The motion of the earth geography chapter talks about how the Earth moves in space, including its spin on its own axis (rotation) and its circular path around the Sun (revolution). This chapter helps us understand why we experience day, night, and different seasons throughout the year.
