Q. Consider the following statements:
1.The tilt of the Earth’ axis remains constant throughout the year.
2.The summer solstice is the time when the sun is directly above the Tropic of Capricorn.
3.The summer solstice leads to an increase in the process of photosynthesis.
How many of the above statements are correct?
Answer: B
Notes:
Explanation –
Statement 1 and 3 are correct. The Earth’s axis is inclined approximately 23.5 degrees relative to its orbital plane around the sun. This tilt remains constant throughout the year, causing changing seasons as Earth orbits the sun. The summer solstice leads to an increase in the process of photosynthesis because there is an increase in solar energy on the day since the Sun is directly overhead.
Statement 2 is incorrect. The summer solstice is the time when the sun is directly above the Tropic of Cancer.
