Schumann resonances are low-frequency electromagnetic peaks in Earth's atmosphere. Named after physicist Winfried Otto Schumann, predicted in 1952. Occur between Earth's surface and ionosphere as a closed waveguide. Appear as peaks at 7.83 Hz, 14.3 Hz, 20.8 Hz, 27.3 Hz, and 33.8 Hz
Seismic tomography images Earth's subsurface using seismic waves. Seismic waves travel through Earth's material, affecting their properties. Tomography creates 2D and 3D models by comparing wave differences
Stars will eventually burn out and become white dwarfs. Universe will expand infinitely, allowing for improbable events. Matter will eventually disintegrate through radioactive decay. Climate change may delay glacial period by up to 50,000 years
USCS evolved from Casagrande's WWII airfield soil classification system. System uses two-letter symbols: first for primary component, second for grain size. Five first-letter symbols: G (gravel), S (sand), M (silt), C (clay), O (organic)
