The Earth in the Solar System Class 6 Notes Geography Chapter 1 - PDF Download

Whenever we look in the sky, there is always that moment of mystery that surrounds our thinking. Do you think about what’s on the other side of the Moon? Will we be able to survive if we go on Mars and other thoughts like that? Well, if you are someone who is always wondering about life outside Earth, then this chapter is made for you. In this chapter, we will be talking about different planets and their relation with Earth along with the solar system.

In the solar system for class 6, students will learn about why the Earth is the only planet in the solar system, which can harness life. Likewise, it is the only planet with water in liquid form. Some facts about the mighty Earth will blow up your mind, and all of these you can find in the solar system for class 6 notes. Our teachers have been teaching students for more than five years. Thus, they have core knowledge of the subjects

Starting with the first fact, which many students might already know but the Earth is a giant planet of the first four planets that are nearest to the Sun. In addition to this, it is the only planet where you can find water in liquid form. This is because Earth is present in the habitable orbit of our solar system. These habitable orbits are present in each solar system. If a planet resides inside it, we can expect life on that planet and water in liquid form. 

Furthermore, the Earth is not the only planet with water in a solid-state. Even Mars has got water in the form of ice, and they used to be water back when the Sun was young and used to be quite hotter than it is today. Our Sun that we see in the night sky is also a star that emits its light and heat. The constellations are the various patterns that we see in the night sky. Different groups of stars form them. When we connect them, they form constellations. Some of the most well-known constellations are Ursa Major and Orion. 


Solar System For Class 6

In ancient times before the maps were made and there was no GPS, people used to navigate at night with stars and constellations. Even today, in army training, cadets are trained to find directions using the constellations and the shadow.

(Our Solar System)

You might not know this, but you can see planets in the night too. You can look for mars in the night, which has a different colour hue, more on the red side than others. The word planet came from the Greek word “Planeta,” which means wanderers. 


Fun Facts About Solar System

Our Earth gets all its heat from the Sun. The Moon that we see in the night sky is the natural satellite of the Earth. From outer space, the Earth appears to be blue as most of the Earth is covered in water, and only 1/3rd of the portion has land on which we have our countries, states, and cities. On the other hand, the Moon is our protective shield. It used to take all the hits from the asteroids, giving Earth the necessary time to form its atmosphere in millions of years. 

In NCERT class 6 geography chapter 1 notes, you will also study the asteroids and how they evaporate when entering the Earth’s atmosphere. After that, you will be learning how the asteroid belt, which is present in between Mars and Jupiter, protects the Earth from bigger asteroids that move in our solar system.

FAQs (Frequently Asked Questions)

1. Is there water present on Mars?

Yes, there is water on mars, but it's not the water you want to drink or take a bath in. The new findings by the NASA mars mission provide the most substantial evidence of liquid water present, which used to flow on mars intermittently. The liquid water that used to be there appears from the steep and relatively warm mountains on the mars' surface. These slopes were first discovered in 2011. 


Also, NASA has found hydrated salt particles on the surface of mars meaning there used to be water flowing in the form of a river in some time in the past. Many scientists believe that we can find frozen water beneath the surface of Mars. There are many predictions of water on Mars. Some scientists even believe that below the Moon's surface, we can find ice, which is as big as California and Texas. 

2. How does the Moon revolve around Earth and not around the Sun?

Moon is the brightest and the biggest object in our night sky. Moon also helps in making Earth the livable planet that it is right now. It makes the planet living by controlling its wobble on the axis. Thus, it results in a more stable climate. In addition to this, the Moon is the reason we have tides in the sea, it's a natural rhythm that has guided mankind millions of times, and it still does its work perfectly. 


The Moon is rotating at the same rate that it revolves around the Earth, known as synchronous rotation. As a result, we can only see the front face of the Moon in the night sky. The Moon makes a complete orbit in 27 days. The gravitational force of the Earth pulls the Moon. As a result, it moves around Earth only. But now here’s a catch, it does revolve around the Sun too. As the gravitational force of the Earth pulls it, the Earth takes the Moon along with it for the circle of the Sun. As a result, the Moon revolves around the Earth and around the Sun too.

3. What is the solar system? Explain in detail according to Class 6.

The sun and all the objects that circle it make up the solar system. Planets, asteroids, comets, and other objects revolve around the Sun. The age of the solar system is estimated to be around 4.6 billion years. The planets and their moons, as well as countless asteroids and comets, are all included. The gravity of the sun keeps all of these things in orbit around it. This indicates that it has a high gravitational pull.

4. What is an orbit accordion to Class 6 Geography?

In Class 6 Chapter 1 Geography the orbit of a planet (or satellite) is the specific and precise elliptical route in which it constantly travels (or satellite). A planet is a celestial body that spins in an orbit around a single star and receives all of its light from that star. Earth is a planetary system. A satellite is a celestial body that orbits around a planet in a certain orbit. The moon is counted as the only natural satellite of the Earth. A detailed explanation is available on the official website of  Vedantu. Students can also access the study material free of cost on the Vedantu App.

5. What is the universe?

The biggest unit in which we dwell in the universe. It's a smattering of galaxies. There is just one Universe, and all that exists inside it is contained within that Universe. Billions of stars constitute the galaxy. Like the solar system, most stars have their own families. Our galaxy, the Milky Way, is where we dwell. All the planets, asteroids, the sun, meteoroids, etc. lie in the universe.

6. What is the significance of the sun in the solar system class 6?

The Sun, eight planets, plus other celestial bodies such as satellites, meteors, comets, and asteroids make up our solar system. There is a lot of significance to the sun. Our solar system's primary source of heat and light is the Sun. All kinds of life on Earth are supported by heat and light. The planets are kept in their orbits by the Sun's gravitational force. Its gravitational force is so strong that no planet goes out of it.

7. What is the Earth?

To begin, many students may already be aware that the Earth is a huge planet and is one of the first four planets closest to the Sun. Additionally, it is the only planet on which liquid water may be found. This is due to Earth's being in our solar system's habitable orbit. Each solar system contains these livable orbits. If it contains a planet, we can expect life on that planet as well as liquid water.
