Gravity is the fundamental force that caused the early Earth to pull material together, forming a spherical shape. A sphere is the most stable shape under gravitational pull for a body of Earth's size.

The atmosphere is the layer of gases surrounding Earth. The photosphere and chromosphere are layers of the sun, not Earth.

Earth's 23.5-degree axial tilt causes different parts of the planet to receive varying solar intensity throughout the year, creating the four seasons. Rotation causes day-night, revolution causes the year.

Earth's rotation on its axis once every 24 hours causes day and night as different parts of the planet face toward or away from the sun. Revolution is the orbit around the sun.

Earth's revolution is its complete orbit around the sun, taking approximately 365.25 days (one year). Rotation is the daily spinning on the axis.

An equinox occurs twice a year when the sun crosses the celestial equator, resulting in approximately equal daylight and nighttime hours everywhere on Earth. This happens around March 21 (vernal/spring equinox) and September 23 (autumnal equinox). The term comes from Latin 'aequinoctium' meaning 'equal night.' Axis is the imaginary line Earth rotates around, and orbit is Earth's path around the sun.
