Build Your Own Earth Spheres Map

Turn your textbook chapter or class slides into a map of the spheres and their links.

Built from your own material

Upload a PDF, DOCX, PPTX or text file and the AI maps the spheres it finds in it.

Expandable branches for each sphere

Open any sphere to add its components, processes and examples as you study.

Quiz and flashcards from the same notes

Turn the map into a quiz or flashcards to test how well you know the four spheres.

How to Make an Earth Spheres Map

Three steps to a clear map of Earth's spheres from your own study material.

  1. 1

    Add your material

    Upload your notes, chapter PDF or slides, or type the topic Earth spheres.

  2. 2

    AI builds the map

    The AI finds the four spheres and their key processes and places them as branches.

  3. 3

    Study, expand and quiz

    Expand any sphere, edit the text, then export the map or test yourself with a quiz.

Understanding the Four Spheres of Earth

Earth is often described as four interacting spheres. The geosphere is the solid Earth, including the crust, mantle and core. The hydrosphere holds all water, from oceans and lakes to groundwater and ice. The atmosphere is the layer of gases surrounding the planet. The biosphere contains all living things, linking the other three spheres together.

  • Geosphere: rocks, minerals, soil, and the crust, mantle and core
  • Hydrosphere: oceans, rivers, lakes, groundwater and ice
  • Atmosphere: gases, weather layers and the water cycle
  • Biosphere: plants, animals, microbes and their habitats
  • Interactions: processes such as weathering, erosion and photosynthesis linking spheres

Use this map to review how each sphere affects the others. To build a version based on your own class notes, create a personalized map with CogniGuide.

Earth Spheres Questions Answered

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

How many spheres does Earth have?

Earth science usually describes four spheres: the geosphere, hydrosphere, atmosphere and biosphere. Some courses add the cryosphere for frozen water, which is often grouped within the hydrosphere.

What is the difference between the geosphere and the lithosphere?

The geosphere covers all of Earth's solid parts, including the core and mantle. The lithosphere is the rigid outer shell made of the crust and uppermost mantle, so it is a smaller part of the geosphere.

Which file types can I use to make an Earth spheres map?

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

Can I turn my Earth spheres map into a quiz?

Yes. You can turn the finished map into a quiz to test yourself on the spheres and their interactions. There is also a free plan with 5 creations per week.
