The document describes the Earth's movements of rotation and revolution that cause natural phenomena. The Earth completes one rotation in 24 hours, which causes day and night. It takes 365 days for the Earth to complete one revolution around the Sun, which divides the year into four seasons as a result. The seasons are spring, summer, autumn and winter, each with characteristic weather patterns and effects on plants and animals.
