Build a Map from Your Earth Science Notes

Turn textbook chapters or lecture slides into a clear map of Earth's layers you can study from.

Start from your own material

Upload a PDF, Word file or PowerPoint on Earth's structure and the AI maps the layers for you.

Layers and properties together

Each layer branches into its composition, thickness, state and boundaries so you can compare them quickly.

Quiz yourself from the map

Turn the finished map into a quiz, or create flashcards from the same notes, before your exam.

How to Make an Earth Layers Map

Three steps from your notes to a map you can expand, test and export.

  1. 1

    Add your notes or topic

    Upload a file on Earth's layers, or type the topic and let the AI start the map.

  2. 2

    AI builds the map

    The generator organizes the crust, mantle and core into branches with their key details.

  3. 3

    Study, expand and quiz

    Expand any layer with more detail, edit the text, then export as PNG or PDF or test yourself.

Understanding the Layers of the Earth Concept Map

A concept map of the layers of the Earth shows how the planet is divided by composition and by physical state. The three compositional layers are the crust, the mantle and the core. The core is split into a liquid outer core and a solid inner core, so a good map separates both the chemical and mechanical views.

  • Crust: thin, rocky outer layer, continental and oceanic types
  • Mantle: thickest layer, mostly silicate rock that flows slowly
  • Outer core: liquid iron and nickel that generates the magnetic field
  • Inner core: solid iron and nickel held under extreme pressure

Use the map to revise the boundaries, such as the Moho and the Gutenberg discontinuity. Then generate a personalized version from your own notes with CogniGuide.

Earth Layers Questions Answered

Common questions about the layers of the Earth and how to map them.

What are the three main layers of the Earth?

The three main compositional layers are the crust, the mantle and the core. The crust is the thin outer rock, the mantle is the thick silicate layer beneath it, and the core is mostly iron and nickel.

Why is the core split into two parts?

The outer core is liquid while the inner core is solid. The difference comes from pressure, which is much higher at the center, even though both are very hot and made mostly of iron and nickel.

Which file types can I use to build an Earth layers map?

You can upload a PDF, a Word (DOCX) file, a PowerPoint (PPTX) file, a text or Markdown file, or an image of your notes. You can also just type the topic.

Can I turn my Earth layers map into a quiz for free?

Yes. The free plan includes 5 creations a week with no payment needed. Your finished map can be turned into a quiz to test your recall of each layer.
