{'ecliptic': [0, 0, 0, 1], 'rotation': [1, 0, 0, 2], 'angle': [0, 0, 1, 0], 'perpendicular': [0, 1, 1, 2], 'axis': [0, 0, 0, 1], 'seasons': [0, 0, 1, 4], 'degrees': [0, 1, 0, 3], 'earth': [0, 1, 1, 1]}

Option 1: There would have been no seasons.

Explanation: The tilt of the Earth`s axis of rotation is responsible for the change in seasons. When the Earth`s axis is tilted towards the Sun, a hemisphere experiences summer, and when it is tilted away from the Sun, the hemisphere experiences winter. If the angle of the Earth`s axis of rotation was 0 degrees, there would be no tilt and no variation in the amount of sunlight received in different hemispheres. This lack of tilt would result in a lack of seasonal changes, and the temperature and climate would be the same throughout the year.

Option 2: The length of day and night would have been the same throughout the year.

Explanation: The tilt of the Earth`s axis also affects the length of day and night. During the summer solstice, the longest day of the year, the hemisphere tilted towards the Sun experiences longer daylight hours and shorter nighttime hours. In contrast, during the winter solstice, the hemisphere tilted away from the Sun experiences shorter daylight hours and longer nighttime hours. If the Earth`s axis had no tilt, the length of day and night would be the same throughout the year.

Option 3: The length of day and night would have been the same all over the Earth.
