Study Notes
Earth's Rotation
- Rotation refers to an object's spinning motion about its axis.
- Axis is the imaginary or invisible line in the center of an object, about which the object spins.
Earth's Rotation Direction
- The Earth rotates from west to east, in an anticlockwise direction.
- This causes day and night in different areas of the Earth.
Sun's Apparent Movement
- The sun's light seems to move around the Earth from west to east.
- This explains sunrises and sunsets, with the sun appearing to rise in the east and set in the west.
Calculating a Year
- One year on Earth is calculated as one complete revolution of the Earth around the Sun.
- This takes approximately 365 and ¼ days.
Leap Year
- A leap year is needed every 4 years to keep time accurate.
- The ¼ days left over from each year add up to make 1 full day, which is added to the end of February.
