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. Variations in the length of day and night time from season to season on the earth's surface is due to the axial tilt of earth's rotation axis with respect to its orbital axis..
3. 23.5 degrees
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
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. ... The day has also been celebrated in many cultures.
2. Earth rotates on its axis; this causes us to experience day and night. But Earth's axis is tilted 23.5 degrees (the angle is measured between Earth's equatorial plane and the plane in which it orbits our Sun).
3. about 23.5 degrees
We have seasons because Earth's axis – the imaginary line that goes through the Earth and around which the Earth spins — is tilted. It's tilted about 23.5 degrees relative to our plane of orbit (the ecliptic) around the Sun
