Sun, Earth, Moon 1
The Earth takes about this amount of time to revolve around the sun?
365 1/4 days
True/False The Moon is a planet.
False
What is approx. 23.5 degrees?
The Earth's axis.
The shape of the moon seems to change because...?
The moon revolves around Earth
The Moon phase that comes directly after the new moon is the.....
the waxing crescent
Earth rotates on its axis once every ...
24 hours
Waxing means the light is _______________ and waning means the light is ___________________.
Waxing means the light is increasing and waning means the light is decreasing.
Earth is tilted toward the sun and there are more hours of daylight. What season is it?
Summer
Why does the moon appear at night?
It reflects light from the sun
The percentage of the Moon that is visible during the first quarter phase.
50%
The Earth's rotation causes .........
day and night
The Earth's revolution around the Sun causes.......
our seasons
Winter is colder because...
Earth is tilted away from the sun.
How many days does it take to see all of the phases of the moon?
28 days
Describe how the sun appears to rise, move across the sky and set for a location on Earth
The sun rises in the East. It moves in an arc up high into the sky and then downward. It sets in the West.
Name the planets that do not have moons
Mercury, Venus
What is mostly responsible for the tidal cycle?
The moon's gravity
If Earth had no tilt, would there be seasonal changes?
No, it's the tilt that causes the seasonal changes
Why isn't there a lunar eclipse every time it is a full moon?
Lunar eclipses do not occur every full moon because the Moon's orbit around Earth is tilted by about 5 degrees relative to Earth's orbit around the Sun. This means that during most full moons, the Moon passes either above or below Earth's shadow, so the alignment needed for an eclipse is not met
In a waning moon, the light is on the....
right
Why is it hotter in Cairns compared to Melbourne when they are in the same hemisphere?
Cairns is hotter than Melbourne because it is located closer to the equator, which receives more direct sunlight year-round.
In contrast, Melbourne is farther from the equator, receiving less direct sunlight.
Explain the alignment of the celestial objects during a Solar Eclipse. What moon phase does this occur in?
Sun, Moon, Earth
New moon
Explain what a Neap tide is, and what moon phase/s it occurs in
A neap tide is when the moon and sun are at right angles, causing the gravitational pull to be shared. This results in lower high tides and higher low tides. Moon phase is the quarter moons.
What is the difference between rotation and revolution?
Rotation occurs when an object spins on it's axis. Revolution occurs when one object moves in a circular path around a second object.
What is the relationship between distance from the sun and orbital period? Give example.
The larger the distance from the sun, the longer it takes to orbit. Example, Mercury is the closet to the sun with the shortest orbital period, where as Neptune is the furthest from the sun with the longest orbital period.
