Layers of the Earth

Use this layers of the Earth template to learn how our planet is built, from the ground beneath our feet to its very center.

The Earth has four main layers:

• Crust: the thin, rocky outer layer we live on. Oceanic crust is thinner and denser than continental crust.
• Mantle: the thickest layer, made of hot rock that moves very slowly and drives the movement of the tectonic plates.
• Outer core: a liquid layer of iron and nickel whose movement creates the Earth's magnetic field.
• Inner core: a solid ball of iron and nickel at the center of the Earth, almost as hot as the surface of the Sun.

Add details about each layer, such as its thickness, composition, temperature and state, to compare them and remember how they work together.

How the Layers Work Together

Layers of the Earth

Use this interactive template to learn about Earth's four main layers, from the surface to its center.

Replace each numbered layer placeholder with the correct layer name, then complete its characteristics, composition, and effects.

Use the suggested ideas within each branch when helpful, or write answers in your own words. Finish by explaining the processes connected to Earth's interior.

Add your lesson notes or an explanation here and link to a trusted Earth-science resource if needed.

Tip: The four numbered branches are fill-in topics. Type each layer name directly into its placeholder instead of adding new branches.

PROCESSES

Complete this section with processes connected to the Earth's layers. Replace each 'add details' placeholder with one short cause-and-effect statement. Use the suggestions for ideas, or add your own examples.

Add explanations or examples in Notes and attach a reliable science resource if useful.

Describe how heat from Earth's deep interior moves toward the outer layers.

Describe the role of Earth's magnetic field, which is generated mainly by moving liquid metal in the outer core.

Describe a process involving magma or volcanic activity.

Describe one process driven by movement or heat within Earth. Express it as a short cause-and-effect statement.

FOURTH LAYER

Choose the correct name for the fourth layer of the Earth from the options below.

❗Only one answer is correct for this position.

Replace the placeholder with your choice, then add details about its characteristics, composition, and conditions in the subtopics.

Describe the pressure deep inside Earth and how it affects this layer's physical state.

Replace 'composition' with the materials found in this layer. You can add more details with Notes.

Compare the temperature of this layer with the other layers.

Describe the physical state and position of Earth's center.

THIRD LAYER

Choose the correct name for the third layer of the Earth from the options below.

❗Only one answer is correct for this position.

Replace the placeholder with your choice, then complete the subtopics with details about its materials, physical state, and properties.

Add a temperature-related characteristic. Use a qualitative statement or a temperature range from your textbook.

Describe an important effect produced by motion in this layer.

Describe the main materials and physical state of this layer.

SECOND LAYER

Choose the correct name for Earth's second layer from the options below.

❗Only one answer is correct for this position.

Replace the placeholder with your choice, then add more details about its characteristics, composition, and effects in the subtopics.

Causes

Explain an effect of the mantle's slow movement. Add the consequence in the empty child topic.

add what it causes

Name one effect of mantle movement on Earth's crust. You can elaborate using Notes.

composition

Replace 'composition' with a short phrase describing this layer's material and physical behavior. Use the child topic to add a more precise term or explanation.

add details

Add a detail about the layer's rock material or related molten material. Be precise: most of the mantle is solid rock, although some rock can partially melt to produce magma.

Explain its temperature or how heat affects the rock.

Describe this layer's size or thickness relative to the other layers.

FIRST LAYER

Choose the correct name for the first layer of the Earth from the options below.

❗Only one answer is correct for this position.

Replace the placeholder with your choice, then use the subtopics to describe its characteristics and contents.

Add one more important characteristic, for example how this layer relates to living things.

Contains

Identify what is found on this layer. Use the empty topics below to add separate examples; keep or remove examples according to your lesson.

Enter another example of what the outer layer contains. You can add more topics if needed.

what does it contain?

Enter one example of what the outer layer contains, such as a landform. Write the answer directly in this topic.

Describe the material and physical state of this layer.

add characteristic

Describe how thick this layer is compared with the others. Keep your answer short and specific.
