At any given time, different parts of the earth experience different seasons. Apart from the earth's revolution around the Sun, which of these is the reason for this?
At any given time, different parts of the earth experience different seasons. Apart from the earth's revolution around the Sun, which of these is the reason for this?
The correct option is C The tilt of the earth's axis of rotation
D. The tilt of the earth's axis of rotation
Seasons happen because Earth's
axis is tilted at an angle of about 23.4 degrees and different parts of Earth
receive more solar energy than others. Because of Earth's axial tilt
(obliquity), our planet orbits the Sun on a slant which means different areas
of Earth point toward or away from the Sun at different times of the year. Around
the June solstice, the North Pole is tilted toward the Sun and the Northern Hemisphere
gets more of the Sun's direct rays. This is why June, July and August are
summer months in the Northern Hemisphere. At the same time, the Southern
Hemisphere points away from the Sun, creating winter during the months of June,
July and August. Summer in the Southern Hemisphere is in December, January, and
February, when the South Pole is tilted toward the Sun and the Northern
Hemisphere is tilted away.
