the phenomena of parallelism of axis?
a- results in the production of day and night
b- causes different hemispheres of the earth to tilt toward the sun
c- determines the angle at which the sun's rays will strike the earth
d- all of the above
The phenomenon of parallelism of axis refers to the fact that the Earth's axis remains parallel to itself as it revolves around the Sun. This means that throughout its annual orbit, the axis maintains the same tilt and orientation.
Now, let's analyze the given options:
a) The parallelism of axis does result in the production of day and night. This is because as the Earth rotates on its axis, different parts of the planet are either facing towards or away from the Sun, leading to the alternation of day and night.
b) The parallelism of axis also causes different hemispheres of the Earth to tilt toward the Sun at various times of the year. This is why we experience different seasons. When a hemisphere is tilted towards the Sun, it receives more direct sunlight and experiences summer, while the other hemisphere is tilted away, receiving indirect sunlight and experiencing winter.
c) The parallelism of axis does determine the angle at which the Sun's rays will strike the Earth. The tilt of the Earth's axis affects the angle at which the Sun's rays hit different parts of the planet, leading to variations in temperature and the changing seasons.
Therefore, the correct answer is d) all of the above. The phenomenon of parallelism of axis influences the production of day and night, causes the different hemispheres of the Earth to tilt towards the Sun, and determines the angle at which the Sun's rays strike the Earth.
