Reading Earth from Core to Space

Introduction

Document Four introduced the Electromagnostat, the thermospheric boundary where the full intensity of the electromagnetic field is modulated into the surface expression that permits life. This document assembles the complete temperature sequence of Earth from inner core to exosphere. It is a picture no one has put together in one place before.

The interior of Earth is studied by geophysicists and geologists. The atmosphere is studied by meteorologists and atmospheric scientists. The thermosphere and ionosphere are studied by space physicists. These communities have their own data, their own journals, their own explanations for what they observe within their domain.

No one has assembled their data into a single sequence and asked what the complete picture means.

This document does that. Read the table below from bottom to top, from the inner core outward to the exosphere, as a single continuous structure.

Layer	Depth / Altitude	Temperature	State	Significance
Inner Core	0–1,220 km depth	5,000–6,000°C	Solid	Iron-nickel at extreme temperature and pressure. Far above Curie temperature of Iron (770°C). No classical ferromagnetism.
Outer Core	1,220–3,480 km depth	4,500–5,500°C	Liquid	Liquid Iron-Nickel. Churning motion generates Earth’s magnetic field. Still far above all Curie thresholds.
Lower Mantle	660–2,900 km depth	3,000–4,000°C	Solid	Dense rock under pressure. Hot enough to flow over extended time.
Upper Mantle	10–660 km depth	700–3,000°C	Plastic	Asthenosphere flows, driving plate tectonics. Curie depth at ~20 km marks where ferromagnetic response ceases.
Crust	0–70 km depth	15°C to 870°C	Solid	Temperature at base approaches Curie range for crustal minerals. Life zone at top surface.
SURFACE: LIFE ZONE	0 km	avg. 15°C	Variable	Chemistry. Biology. Liquid water. All downstream domains. Bounded above and below.
Troposphere	0–12 km	15°C to -60°C	Gas	All weather. 99% of water vapor. Temperature drops with altitude.
Stratosphere	12–50 km	-60°C to -15°C	Gas	Ozone absorbs UV. Temperature rises, first upward reversal above surface.
Mesosphere	50–85 km	-15°C to -90°C	Gas	Coldest point in the entire Earth system. The thermal floor. Boundary between surface zone and Electromagnostat above.
Thermosphere	80–600 km	-120°C to 2,000°C+	Plasma	Temperature rises sharply. Spans and exceeds all Curie temperatures. The Electromagnostat. ISS orbits here.
Exosphere	600–10,000 km	Transitional	Plasma/Vacuum	Fades into interplanetary space. Earth’s electromagnetic field merges with the solar field.

Three Observations the Sequence Reveals

First, Earth has two zones of extreme temperature separated by the entire inhabited world. The inner core at 5,000 to 6,000°C from below. The thermosphere at up to 2,000°C and above from above. Between them, every other layer sits at intermediate conditions. The life zone occupies the narrow band where these two extremes are furthest apart.

Second, the coldest point in the entire Earth system is the mesopause at approximately -90°C. It sits at 85 kilometers altitude, directly between the surface life zone and the thermospheric Electromagnostat above it. This is the thermal floor. The deepest point of cooling in the system. It is not incidental. It is the structural boundary that separates the biological world from the full encounter intensity of the electromagnetic field above it.

The life zone is bounded above by the mesopause and below by the Curie depth. It does not sit arbitrarily on Earth’s surface. It sits in a precisely bounded thermal valley between two structural limits, one electromagnetic, one thermal.

Third, the Curie depth at approximately 20 kilometers below the surface marks the downward boundary of organized ferromagnetic response in the crust. Above it, crustal rocks respond coherently to the electromagnetic field. Below it, temperatures exceed the Curie thresholds of every ferromagnetic mineral and organized magnetic response ceases. The life zone sits directly above this downward boundary, in the zone where the crust still maintains organized electromagnetic response.

The life zone is therefore held between two boundaries that the framework identifies as structurally related: the mesopause above, the lower limit of the Electromagnostat and the Curie depth below, the upper limit of the thermally disordered interior. Between them, the electromagnetic field operates in its organized surface expression. Within that organized expression, every downstream domain exists.

What Conventional Science Has Not Asked

Conventional geophysics explains each layer separately. Mantle convection explains mantle temperatures. Ozone chemistry explains stratospheric warming. Mesospheric thinning explains mesospheric cooling. Thermospheric absorption explains thermospheric heating. Each explanation is local and discipline-specific.

No conventional framework has assembled these separate explanations and asked: why do all these independent processes conspire to produce a life zone at exactly the temperature and pressure range where chemistry and biology can operate? Why is the coldest point in the system positioned precisely between the biological world and the electromagnetic encounter zone? Why does the Curie depth sit just below the zone of life?

The Lilborn Equation Framework asks all three questions simultaneously and finds that the answer to each is the same: the electromagnetic field, organizing through coherence and encounter geometry, produces the conditions its downstream domains require. The sequence is not a coincidence. It is a structure.
