Concept:The Earth’s axis is tilted relative to its orbital path around the Sun.
Explanation:The plane of the Earth’s orbit is called the plane of the ecliptic.
A line perpendicular to this plane would make a
90∘ angle with it.
The Earth’s axis is tilted
23.5∘ away from that perpendicular.
Therefore, the angle between the Earth’s axis and the plane of the ecliptic is:
90∘−23.5∘=66.5∘This is usually rounded to
66∘ in geography examinations.
This tilt causes the seasons and varying day length.
Answer:A.
66∘
