Students may be asked to write a paragraph on “The Layers of the Earth” as it is an important topic in school exams. The Earth is made up of four layers, each with unique properties. Together, they shape our planet and support life. Please check the various versions (in 100 words, 150 words, 200 words, and 300 words) provided below for the paragraph.
Paragraph on ‘The Layers of the Earth’ in 100 Words
The Earth has four layers: the crust, mantle, outer core, and inner core. The crust is the hard outer layer where we live. It’s made of rocks and soil. Beneath the crust is the mantle, which is thick and made of hot, soft rock. The outer core is made of liquid metal, and it’s very hot. The inner core is the very center of the Earth, and it’s made of solid metal. The layers of the Earth work together to make the planet’s surface change and help keep the Earth warm.
Paragraph on ‘The Layers of the Earth’ in 150 Words
The Earth has four layers: the crust, mantle, outer core, and inner core. The crust is the outer layer, and it is made of rocks and soil. It’s thin compared to the other layers, but it’s where we live. Beneath the crust is the mantle. The mantle is very thick and made of hot, soft rock. It moves slowly and causes earthquakes and volcanoes. Below the mantle is the outer core. The outer core is made of liquid metal, like iron and nickel. It’s so hot that the metal is in liquid form. At the very center of the Earth is the inner core. The inner core is made of solid metal and is even hotter than the outer core. These layers work together to create Earth’s surface and keep the planet warm.
Paragraph on ‘The Layers of the Earth’ in 200 Words
The Earth has four layers that each play a special role. The outermost layer is the crust. The crust is where we live and is made of rocks and soil. It’s thin compared to the other layers, but it covers the entire Earth like a shell. Beneath the crust is the mantle. The mantle is very thick and made of hot, soft rock. It moves slowly, and this movement can cause earthquakes and volcanoes. The mantle is so hot that parts of it melt, creating magma, which can flow out through volcanoes.
Below the mantle is the outer core. The outer core is made of liquid metal, mostly iron and nickel. It’s extremely hot, around 4,000 to 5,000°C. The movement of the liquid metal in the outer core helps create Earth’s magnetic field. At the very center of the Earth is the inner core. The inner core is made of solid metal, and it’s even hotter than the outer core. Even though it’s so hot, the pressure inside the Earth makes the inner core solid. All of these layers work together to create the Earth’s surface, support life, and keep the planet warm.
Paragraph on ‘The Layers of the Earth’ in 300 Words
The Earth has four layers that are very different from each other. The outer layer is called the crust. The crust is the thinnest layer, and it’s where we live. It’s made up of rocks and soil. The crust can be thick or thin depending on where you are. It covers the Earth like a shell, and we see mountains, valleys, and oceans on the crust. Beneath the crust is the mantle. The mantle is much thicker and made of hot, soft rock. This layer moves slowly, which causes earthquakes and volcanoes. The mantle is very hot, and parts of it melt into a substance called magma. This magma rises to the surface during volcanic eruptions.
Below the mantle is the outer core. The outer core is made of liquid metal, mostly iron and nickel. The temperature in the outer core is extremely hot, between 4,000°C and 5,000°C. The liquid metal in the outer core moves around, and this movement creates Earth’s magnetic field, which protects the planet from harmful solar radiation. At the very center of the Earth is the inner core. The inner core is made of solid metal, even though it’s very hot. The pressure inside the Earth is so high that the metal remains solid despite the heat. The inner core is even hotter than the outer core.
All of these layers work together to shape the Earth. They help create the surface we see, cause volcanoes and earthquakes, and keep the planet warm enough for life. Understanding the layers of the Earth helps us learn more about how our planet works.

Why Can’t We Dig a Hole Through The Centre of the Earth?
We can’t dig through Earth because it’s too hot, has extreme pressure, and consists of solid and molten layers, making it impossible to survive.
Short Paragraph on ‘The Different States of Matter (Solid, Liquid, Gas)’
Matter exists as solid, liquid, or gas. Solids have fixed shapes, liquids flow, and gases spread freely. Heat can change matter between these states.
What is Inside the Earth?
Earth has four layers: the crust (outer layer), mantle (hot rock), outer core (liquid metal), and inner core (solid metal, very hot).
Write a Paragraph on ‘What Causes Volcanoes to Erupt?’
Volcanoes erupt when hot magma, gases, and pressure build up inside Earth. When pressure becomes too high, magma escapes through openings, forming lava and ash.
Paragraph- ‘The Rock Cycle’
The rock cycle changes rocks over time. Heat, pressure, and weathering turn rocks into igneous, sedimentary, or metamorphic forms, constantly reshaping Earth’s surface.
