Sun’s rays can make right angle only up to 23(1/2) and South latitudes because

Key Points

• The Sun's rays can make a right angle only up to 23(1/2) degrees North and South latitudes due to the Earth's axial tilt.
• The Earth is inclined at an angle of 66(1/2) degrees on its axis relative to its orbital plane.
• This axial tilt is responsible for the variations in the angle at which sunlight strikes the Earth at different latitudes.
• The regions between the Tropic of Cancer (23(1/2) degrees North) and the Tropic of Capricorn (23(1/2) degrees South) are the only areas where the Sun can be directly overhead at noon.
• This phenomenon is crucial for understanding seasonal changes and the distribution of solar energy on Earth.

Additional Information

• The Earth's axial tilt of 66(1/2) degrees is measured from the perpendicular to its orbital plane, which is why it is also described as being tilted 23(1/2) degrees from the vertical.
• This tilt is the reason we experience different seasons throughout the year.
• When the Northern Hemisphere is tilted towards the Sun, it experiences summer while the Southern Hemisphere experiences winter, and vice versa.
• The concept of Earth's axial tilt is fundamental to the field of astronomy and geography.
• Understanding the Earth's tilt helps explain the climatic zones and the distribution of ecosystems around the planet.
