Build Your Earth System Map

Turn your earth science material into a map that shows how the spheres and cycles connect.

Use your own material

Upload lecture slides, textbook chapters or notes and get a map of the earth system topics they cover.

Spheres and cycles clearly linked

Branches separate each sphere, then connect them through water, carbon and nitrogen cycles and energy flow.

Quiz and flashcards from the map

Test yourself with a quiz built from the map, or create flashcards from the same notes before your exam.

How to Make an Earth System Map

Three steps to a study map of the earth system, built from your own material.

  1. 1

    Add your material

    Upload a PDF, slides or notes on the earth system, or just type the topic.

  2. 2

    AI builds the map

    The AI groups spheres, cycles, feedback loops and processes into expandable branches.

  3. 3

    Study, expand and quiz

    Expand any node for more detail, edit labels, export as PDF or PNG, and turn the map into a quiz.

Earth System Concept Map Explained

An earth science concept map of the earth system shows how Earth works as one connected system. It divides into four spheres: the atmosphere (air and weather), the hydrosphere (oceans, ice and fresh water), the geosphere (rock, soil and the mantle and core) and the biosphere (all living things). Energy from the Sun drives these spheres, and matter moves between them through cycles.

  • Atmosphere: gases, weather patterns and climate drivers
  • Hydrosphere: water cycle, ocean circulation and ice
  • Geosphere: plate tectonics, rock cycle and soils
  • Biosphere: carbon and nitrogen cycles and ecosystems
  • Feedback loops: positive and negative changes that stabilize or amplify the system

Use the map to revise how the spheres interact and where the cycles overlap. To make a version based on your own lecture notes, try CogniGuide's AI mind map generator.

Earth System Map Questions

Answers on the earth system and making your own map.

What are the four spheres of the earth system?

The four spheres are the atmosphere (air), hydrosphere (water), geosphere (solid Earth, including rock and soil) and biosphere (living things). Scientists study how energy and matter move among them.

What is a feedback loop in the earth system?

A feedback loop is a process where a change produces a response that either strengthens it (positive feedback) or weakens it (negative feedback). Ice melting that exposes darker ocean water, which absorbs more heat, is a common example of positive feedback.

Which files can I upload to make my earth system map?

You can upload PDF, Word (DOCX) or PowerPoint (PPTX) files, text or Markdown files, or images. You can also type a topic and let the AI build the map.

Is it free to create an earth system concept map?

Yes. The free plan allows 5 creations a week with no payment needed. Paid plans raise the limits.
