Moon
PRETEST
Name:
Sherylyn Richards McNamara
Answer each question based on your current
understanding of sun-Earth-moon spatial relationships.
1. Briefly explain the cause(s) of day (period of
light) and night (period of darkness) that we experience on Earth.
The pull from
the sun makes the Earth turn
2.
Briefly
explain the reason why our summers are warm and our winters are colder.
The Earth is
closer to the sun in Summer and away from the sun in winter
3.
Briefly
explain why our sun appears to move from east to west across the sky?
The sun
blocks the moon
4.
Briefly
describe the apparent movement, if any, of the moon across the sky during a
24-hour period.
The sun
blocks the moon
5.
Explain
why the moon is sometimes visible during daylight hours.
The sun is
not blocking during those hours
6.
Explain
why the same half of the moon always faces the Earth.
The sun cast
the lightfro us to see the moon
7.
What
is the source of the moon’s light?
The sun
8.
Explain
why some Earth locations can have days when the sun never sets (24 hours of
light) and days when the sun never rises (24 hours of darkness).
9.
If
people lived on the moon and observed Earth on a regular basis, would Earth
appear to have phases (different shapes)? Explain
Yes, because the
light from the sun would make the Earth look different shapes as it does the
moon.
10.
Using
the diagram below, draw where the moon would be during a new moon. A new moon
is when none of the moon is visible from Earth. Explain your reasons for your
placement of the moon.
Because the Earth blocks the moon from the light the sun will give
the moon.So the moon is behind the Earth.
Corrected Pretest:
1. The sun rotates on its axis each day and as it
rotates the sun will shine on the part of the Earth facing the sun causing
day. The Each turns away from the sun on
its axis each day causing night.
2. The
Earth has a tilt, and sometimes the Earth’s axis is titled away from the sun
and other times it is tilted towards the sun.
The directness of the sunlight and the Earths tilts cause the
seasons. In summer the Earth gets more
direct sun light which leads to hotter and longer days.
3. The
sun appears to move east to west because of the Earth’s counterclockwise rotation.
4. The
Moon orbits around the Earth from east to west
5. The
Earth is rotating faster than the moon orbits causing it to reflect light from the
Sun at the same time the sun is still visible during the day.
6. The
moon’s rotation is the same as its revolution
7. The
sun is the moon’s light source
8. The
Earth’s tilt on its axis can cause some areas on Earth where the sun never set
or rises during parts of the year.
9. Yes
it would be the same for the moon people as it is the Earth people because the
sun is Earths’ light source so the Earth would have phases like the moon.
10. The
moon is between the sun and Earth so during a new moon the sun is directly
behind the moon and does not shine on the side towards Earth causing the moon
to be unseen.
