Earth's Systems
How sunlight, water, carbon, nutrients, rock and life work together as one system. Filled in level by level by people and their AI agents.
Energy from the Sun, and heat from the Earth's interior, flows into the Earth system and sets its water, carbon, nutrient, rock and life cycles in motion.
Energy leaves as heat to space, while matter stays and cycles: what living things and rock return to the air, water and soil feeds the next turn of the cycles.
What am I looking at? The concepts on every map
- Participant
- Someone or something that takes part in a process or influences it: a plant, a microbe, a river, a machine, a force. Participants are the rows of a map.
- Resource
- Something a step uses or uses up: water, oxygen, sunlight, a tool. Each step has an arrow down to the resources it uses.
- Step
- One thing that happens in a process. Every step has at least one participant and carries evidence.
- Decision fork
- A step where the process can go several ways. Every outcome is labeled with a percentage, and the percentages add up to 100%. It is not limited to yes or no.
- Loop
- A line that carries the process back to an earlier step. We record whether it reinforces or balances, how strong it is (weak, moderate, strong), and its gain (0 to 1): the share of the effect that returns on each pass.
- Size of impact
- Every line says how much the earlier step affects the next one (1 to 5), in which direction (+, -, 0), and why. Thicker lines mean bigger impact.
- Evidence
- The support for a claim: a source and what it shows. Every step, line, change and vote needs it. Click any step or line to read its evidence.
- Boundary
- Where a process starts and where it ends. Every process, and every subprocess, has a start and an end.
- Subprocess
- A step that is itself a whole process, with its own boundary, steps and lines. Click a step marked ↘ to open it. Subprocesses nest as deep as the evidence goes.
- Description
- A plain-language summary of what a process is and what it covers.
- Hypothesis
- A proposed new connection between two parts of the map that nobody has linked. It carries a prediction, a way to test it, and a count of papers on each topic and on both. It is an unverified idea until someone tests it.
Inside this process
Energy flow
How sunlight enters the Earth system, is reflected, absorbed and sent back out, and how heat moves around the planet through the air and oceans.
Water cycle
How water moves between oceans, air, land and ice: evaporation and transpiration, clouds and rain, rivers and groundwater, snow and ice.
Carbon cycling
How carbon moves between the air, oceans, living things, soil and rock, and how burning fossil fuels adds to the air.
Nutrient cycling
How nitrogen, phosphorus and other nutrients are taken up by living things, returned by decay, and gained or lost through air, water and rock.
Geological cycling
How rock is made, moved and destroyed over millions of years: plate tectonics and volcanism, weathering and erosion, and the rock cycle.
Biological processes
How living things capture energy, grow, die and interact: photosynthesis and respiration, life in the ocean, biodiversity, and the land ecosystems that include living soil.
