Study Notes
Sun Position and Seasons
- The Sun is highest in Sydney, Australia at noon during the winter solstice on December 21.
- For equatorial regions, the Sun is in its northern path above at noon from March 21 to September 21.
- On December 21, the Sun is directly overhead at the Tropic of Capricorn, positioned at 23.5 degrees South latitude.
Seasonal Changes
- The first day of spring for Australians occurs around September 21.
- If the Earth were tilted to 45 degrees instead of 23.5 degrees, winter temperatures in Colorado would be significantly colder.
- In the absence of the Earth's axial tilt, June temperatures in Colorado would also be colder than they are currently.
Extreme Tilts Impact
- A tilt of 90 degrees would result in summers in the Arctic being warmer than summers in Colorado.
- On Mars, summers in the Northern Hemisphere are generally colder compared to those in the Southern Hemisphere.
- Conversely, winters in the Northern Hemisphere on Mars are typically warmer than in the Southern Hemisphere.
