10. The Earth is tilted on its axis as shown in the picture on the right.
What would change if the Earth's axis was not tilted but
straight up and down like in the picture at the left?
A. The Earth would not have seasons.
B. The Earth would stop orbiting the sun.
C. At the equator there would be 24 hours
of daylight
D. The daytime temperature at the North
Pole would be the same as the equator.
Answers
Answer:
A. The Earth would not have seasons.
Explanation:
What if the Earth's axis was not tilted? The Earth would no longer tilt to the right, as it does in the figure above. Instead, it would point straight up, and would rotate every day around that straight-up axis.
Answer:
Final Answer.
Explanation:
Given,
The earth is tilted on its axis.
Concept:
The initial, obvious result of the Earth having zero obliquity would be that the seasons would be much less pronounced, and that the Earth would have the same season all over the planet.
The season would result from the eccentricity of the Earth’s orbit. Mid-summer would be around January 3rd, and mid-winter would be around July 3rd. These seasons would be much less pronounced than the seasons caused by the Earth’s obliquity.
The result of having much less pronounced seasons would be that there would not be an annual growth cycle for plants. Plants could germinate, grow, flower and seed at any time of year.
This, in turn would have an effect on animals, especially those which migrate to follow their food source. Think especially of the migratory birds and the wildebeest on the East-African plains.
A secondary effect of the Earth having zero obliquity would be that all days would have nearly the same length of daylight. This effect would be slightly modified by the orbital eccentricity, but to nowhere near the same degree as that caused by the obliquity.
Under these conditions, the sun would rise almost due east every day, and set almost due west.
Therefore, the correct answer is
The earth would not have seasons.
