Q&A STUDY GUIDE UPDATED 2026
◉ rotation of the earth on its axis. Answer: what causes day and night?
◉ east to west, because of Earth's rotation. The stars and planets move in
the same way from our point of view, also, because of Earth's rotation.
Answer: how does the sun appear to move in the sky in the course of a
day?
◉ it orbits the sun, once (also known as one complete revolution about
the sun). Answer: what happens to the earth in one year?
◉ the tilt of the Earth's axis of rotation, with respect to the plane of its
orbit around the Sun (and not because of changing distance from sun).
Answer: why do we have seasons?
◉ 23 degrees. Answer: what is Earth's approximate axial tilt?
◉ with the North Pole toward the sun. Answer: how is Earth's axis tilted
when we have summer in the Northern hemisphere?
,◉ winter. Answer: What season is it in the Southern Hemisphere when it
is summer in the northern hemisphere?
◉ December 21. Answer: in the northern hemisphere, when does winter

◉ during the day. it transits at noon; it rises 6 hours earlier (at sunrise)
and sets 6 hours later (at sunset). Answer: when is the new moon
visible?
◉ in a straight line: sun- moon - earth. Answer: how are the sun, earth,
and moon positioned when it is new moon?
◉ sun - earth - moon. Answer: how are the sun, earth, and moon
positioned when its a full moon
◉ the moon is blocking the suns light, or a location on the earth's
surface is passing under the moon's shadow. Answer: what is a solar
eclipse?
◉ suun - moon - earth (as in a new moon). Answer: how are the sun,
earth, and moon positioned when it is a solar eclipse?
◉ earth's shadow passes across the moon. Answer: what is a lunar
eclipse?
