Earth’s magnetic field (collection)
A graphics collection representing multiple interesting aspects related to the Earth’s magnetic field.
Earth’s magnetic field (overview)
Schematics outlining key elements of the Earth’s magnetic field that is produced in the hot, liquid Outer Core, varies in strength, and even reverses multiple times through the planet’s evolution.
Planetary spheres art
100-km depth contours outline the basic radial compositional structure of the planetary interiors of Earth, Mars, Venus, and Mercury.
Surface topography cross-section art
The global bedrock relief model of the Earth’s surface along the equator integrating land topography and ocean bathymetry reveals the vastness of the ocean depths.
Planetary spheres
Planetary interiors represented by 100-km depth contours outlining the basic compositional structure.
Earth’s mantle heterogeneity theories
Conceptual model sketches for proposed compositional structures of Earth's mantle, including "Marble cake", "Thermo-chemical piles", and "Mid-mantle blobs" theories.
