Earth Beneath — Cross Section to Scale

Geology Interactive Visualization

Scroll to descend through the continental crust at true scale — 10 pixels = 1 meter (1 pixel ≈ 10 cm). Depths shown are representative; real geology varies enormously by location.

Scale: 10 px = 1 m  ·  House ≈ 4.5 m  ·  Representative continental crust ≈ 35 km to the Moho  ·  Scroll to descend Fact-checked anchors: Mponeng mine 4.0 km · Kola borehole 12.262 km · Moho depth varies ~25–70 km by region (35 km used here as a typical shield value). Temperatures are rough estimates using a ~25 °C/km geothermal gradient.

Mohorovičić Discontinuity (Moho)

Base of the continental crust at ~35 km in this model.
Below lies the upper mantle — solid silicate rock under extreme pressure, not a magma ocean.
You scrolled through 35 km of crust. The mantle continues another 2,800+ km to the core.
