Study Notes
Earth's Shape and Motions
- The Earth is a geoid, a slightly flattened sphere bulging at the equator.
- A globe is a model of the Earth, representing its shape with an axis.
- The Earth has an axis connecting the North and South Poles.
- An imaginary line called the Equator divides the Earth into the Northern and Southern Hemispheres.
Earth's Rotation
- Rotation is the Earth spinning on its axis.
- Rotation causes day and night.
- The part of the Earth facing the Sun experiences day, while the other half experiences night.
- The Earth rotates from west to east.
- One rotation takes approximately 24 hours (one day).
- Rotation also causes winds and ocean currents.
- The axis of rotation is tilted at 23.5 degrees.
Earth's Revolution
- Revolution is the Earth orbiting the Sun.
- The Earth takes 365.25 days to complete one revolution.
- The Earth's revolution is responsible for the seasons.
- The Earth's orbit is not a perfect circle; it's slightly elliptical.
- The tilt of the Earth's axis causes the variation in the intensity of sunlight received by different parts of the globe, leading to seasons.
Cycle of Seasons
- The tilt of Earth's axis (23.5 degrees) is the primary cause of seasons.
- Seasons are caused by the changing angle of sunlight on Earth's surface as it orbits the Sun.
- The Earth's axis points in the same direction as it orbits the Sun.
- Different parts of the Earth experience varying amounts of direct sunlight throughout the year, influencing temperature changes.
- The Earth's tilted axis, combined with its revolution around the Sun, creates the cycle of seasons.
