d. write short answers. 1. what happens on the summer solstice? 2. what causes variations in the duration of day and night?
3. At what angle is the earth's axis inclined to its plane of orbit?
Answers
Answer:
1. At the summer solstice, the Sun travels the longest path through the sky, and that day therefore has the most daylight. When the summer solstice happens in the Northern Hemisphere, the North Pole is tilted about 23.4° (23°27´) toward the Sun
2. The change between day and night is caused by the rotation of the Earth on its axis. ... The changing lengths of days and nights depends on where you are on Earth and the time of year. Also, daylight hours are affected by the tilt of the Earth's axis and its path around the sun.
3. 23. 5 degrees is the angle. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists.
