How The Earth Moves
key notes :
- Rotation:
- Earth spins or rotates on its axis.
- It takes approximately 24 hours for the Earth to complete one full rotation.
- Rotation causes day and night. The side facing the sun has daylight, while the side facing away has night.
- Axis:
- The Earth’s axis is an imaginary line running from the North Pole to the South Pole.
- Tilted at an angle of about 23.5 degrees.
- The tilt is responsible for the changing seasons.
- Day and Night:
- Day and night occur because of the Earth’s rotation.
- When your part of the Earth faces the sun, it’s day. When it faces away, it’s night.
- The Sun’s Path:
- The Sun appears to rise in the east and set in the west due to the Earth’s rotation.
- Revolution:
- Earth also moves in an orbit around the Sun.
- It takes about 365.25 days to complete one orbit, which is why we have leap years.
- Seasons:
- The Earth’s tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year.
- This leads to the changing seasons – spring, summer, autumn, and winter.
- Equator and Poles:
- The equator is an imaginary line around the Earth’s middle, dividing it into the Northern and Southern Hemispheres.
- The North Pole is in the Northern Hemisphere, and the South Pole is in the Southern Hemisphere.
- Solstices and Equinoxes:
- The summer and winter solstices occur when the North or South Pole is tilted closest to the Sun.
- The spring and autumn equinoxes occur when day and night are approximately equal in length.
- Time Zones:
- The Earth is divided into 24 time zones.
- Time zones help us keep track of time as the Earth rotates.
- Why Earth’s Movement Matters:
- Understanding how the Earth moves helps us explain day and night, seasons, and time differences.
- It’s crucial for navigation, agriculture, and our daily lives.
Additional Information:
- The study of Earth’s movements is called “Astronomy.”
- The Earth’s rotation and orbit are essential for life and maintaining our planet’s climate.
