What are the 7 Layers of Earth

what are the 7 layers of earth

Looking at the Earth from space is an amazing experience. The different colors and shapes of the continents are incredibly beautiful, and it’s easy to see how everything on our planet is interconnected. In this article, we take a closer look at the 7 layers of Earth, and how they’re all important for us humans.

The Inorganic Layer

The first layer of Earth is the inorganic layer. This layer is made up of elements such as silicon, oxygen, and potassium. This layer is very thin and covers only about 2% of the Earth’s surface.

2. The Organic Layer

The second layer of Earth is the organic layer. This layer contains plants and animals. It covers about 55% of the Earth’s surface. This layer is very important because it provides food for other creatures.

The Organic Layer

The first layer of the earth is the organic layer. This layer is made up of plants and animals that died a natural death. This includes things like leaves, flowers, trees, and insects.

The second layer of the earth is the mineralogical layer. This layer contains rocks and minerals that were created when water, gas, and rocks melted together. It includes things like sand, clay, and metals.

The third layer of the earth is the physical layer. This layer contains everything else including Earth’s core and surface!

The Lithosphere

The Lithosphere is the outermost layer of the earth. It’s made up of the Earth’s solid rock and is about 100 kilometers thick.

2. The mantle
The mantle is the layer below the Lithosphere. It’s made up of hot, melted rock and is about 1,500 kilometers thick.

3. The core
The core is the middle layer of the earth. It’s made up of solid iron and is about 2,700 kilometers thick.

The Asthenosphere

The Asthenosphere is the third layer of the Earth’s mantle. It sits below the lithosphere and upper mantle and extends from the surface to a depth of about 300 km.

The Asthenosphere is made up of two parts: the lithosphere and the asthenosphere. The lithosphere is a solid layer that covers the entire planet. The asthenosphere is a softer, more ductile layer that sits on top of the lithosphere.

The asthenosphere has a number of important features that affect how the Earth works. For example, it affects how heat gets transferred from the core to the surface, and it affects how earthquakes happen.

The Mantle

The mantle is the layer of earth that sits atop the planet’s core. It’s made up of solid rock and is about 5,500 miles thick.

2. The Core
The core is the center of the Earth. It’s made up of molten rock and is about 5,989 miles thick.

3. The Crust
The crust is the outermost layer of the Earth. It’s made up of solid rock and is about 2,000 miles thick.

The Crust

The Crust is the outermost layer of Earth. It is made of solid rock and is about 100 kilometers thick.

The Crust contains most of the Earth’s water and is a major source of food for plants. It also protects the planet from the effects of earthquakes and volcanoes.

The Crust plays an important role in the climate system. It helps to regulate the Earth’s temperature by reflecting sunlight back into space.

The Crust is also a source of minerals, including diamonds and other precious stones.

Conclusion

The seven layers of earth are: the Earth’s crust, the mantle, the lower mantle, the upper mantle, the outer core, the inner core and the Earth’s atmosphere.
