Which of the following explains why seasonal conditions vary in different parts of the world?
A
The gravitational pull of the Moon on the Earth's oceans.
B
The varying distance between the Earth and the Sun during the year.
C
The tilt of the Earth's axis relative to its orbit around the Sun.
D
The rotation of the Earth on its axis every 24 hours.
Verified step by step guidance1
Understand that the Earth's axis is tilted at an angle of approximately 23.5 degrees relative to its orbit around the Sun. This tilt is crucial in explaining seasonal variations.
Recognize that as the Earth orbits the Sun, different parts of the Earth receive varying amounts of sunlight at different times of the year due to this axial tilt.
During one part of the year, the Northern Hemisphere is tilted towards the Sun, resulting in longer days and more direct sunlight, which causes summer in that hemisphere.
Conversely, when the Northern Hemisphere is tilted away from the Sun, it experiences shorter days and less direct sunlight, leading to winter.
The Southern Hemisphere experiences opposite seasons to the Northern Hemisphere at any given time due to the same axial tilt, explaining the variation in seasonal conditions globally.
