Shape and Structure
Earth is an oblate spheroid, slightly flattened at the poles and bulging at the equator. Its internal structure consists of the crust, mantle, outer core (liquid), and inner core (solid).

Tectonic plates
Earth’s lithosphere is divided into tectonic plates that float on the semi-fluid asthenosphere. Plate movements cause earthquakes, mountain formation, and volcanic activity.
Surface
Earth’s surface is 70% water and 30% land, consisting of continents, islands, oceans, rivers, and deserts. Its diverse terrain supports life.
Atmosphere
Earth’s atmosphere is a layer of gases, primarily nitrogen (78%) and oxygen (21%), which protects life from harmful solar radiation and maintains temperature.
Weather, Climate, and Water Cycle
Weather describes short-term atmospheric conditions, while climate refers to long-term patterns. The water cycle involves evaporation, condensation, and precipitation, regulating life-supporting processes.
Orbit and Rotation
Earth orbits the Sun in an elliptical path, completing one revolution in 365.25 days. Its 24-hour axial rotation causes day and night. The tilt of its axis results in seasons.
