Seasonal changes are related to the length of a day and the height of the Sun in the sky. Describe how these two factors change throughout a year, and how this relates to the seasonal changes you observe in your home town.
Answer:
it presents a cause and effect perspective
Explanation:
The axis of the Earth rotates in relation to the Sun as it revolves around it, the height of our Sun as seen above the horizon changes as a result of this.
What are seasonal changes?Our Sun is seen to trace a higher route above the horizon in the summer and a lower path in the winter at any given place on Earth.
Since the Earth is slightly inclined toward the Sun during the summer, we are warmed and experience longer, brighter days.
Based on our location, the Earth is tilted away from the Sun throughout the winter, making the days colder, shorter, and with less sunshine.
Therefore, the tilt of a planet's axis and its orbit around the sun are causes of seasons.
