The Earth gradually increases in size over time, with this expansion causing continental separation and mountain building, and the ocean floor spreading as the planet grows.
Expanding earth theory was proposed as an alternative to plate tectonics in the 1950s-1960s, but it contradicts astronomical observations and the conservation of mass. The Earth's mass remains essentially constant, and precise satellite measurements show no measurable expansion. Plate tectonics successfully explains all the phenomena that expanding earth attempted to account for , continental drift, seafloor spreading, and mountain building , through a static-sized planet with moving crustal plates.
