The Earth In Motion (1936)

The film explains the evidence supporting the Earth’s shape and motion, highlighting observations such as a ship disappearing below the horizon, the apparent motion of stars due to Earth’s rotation, and the behavior of a Foucault pendulum. It illustrates the Earth’s revolution around the Sun, using the changing position of the constellation Leo and the concept of apparent motion of nearby stars. The film also discusses the elliptical orbit of Earth, variations in distance from the Sun, and the effect of the Earth’s axial tilt on seasonal changes, culminating in a depiction of the seasons experienced in temperate zones.
