Why do the Sun and Moon appear to move across the sky?

The rotation of Earth makes the Sun and Moon seem to move.
The Sun and Moon revolve around the Earth.
The Earth revolves around the Sun and Moon.
Everything is brighter at night when there is a full moon because the Moon is
giving off its own bright light.

Which of the following explains why in Bronson it is warmer in July than in January?
The Sun gives off more heat energy in July.
Earth is closer to the Sun in July.
The Sun is higher in the sky and provides more hours of daylight in July.
The Northern Hemisphere is tilted away from the Sun in July.
Earth rotates on its axis, the Moon
also rotates, but it rotates much faster than the Earth's rotation.
also rotates, but at the same speed as Earth's rotation.
also rotates, but at a much slower speed than Earth's rotation.
does not rotate.
What causes the seasons?
The elliptical movement of Earth around the Sun
The tilt of the Earth on its axis at various points in its revolution around the Sun.
The ways in which solar winds strike the Earth at different angles.
The amount of time that has passed since the last lunar eclipse.
When the Earth is between the moon and the sun there is a
new
full
crescent
gibbous
When there is a solar eclipse, what is the order of the Sun, Earth and Moon?
Sun, Moon, Earth
Sun, Earth, Moon
Earth, Sun, Moon
Some other order
Which of these has the biggest effects on high and low tides
The mass and gravity of the Sun
The mass and gravity of the Moon
The mass and gravity of Earth
The depth of the water that is having the tides.
A solstice is a time when the amount of daylight is at the longest or shortest it will be all year. In which 2 seasons do we get solstices?
fall and winter
winter and spring
summer and winter
fall and spring
An equinox is a time when the amount of daylight is exactly equal to the amount of night time we get in a day. During which 2 seasons do we get equinoxes?
fall and winter
winter and spring
summer and winter
fall and spring
In Florida, the days are much shorter during the winter than they are during the summer. Which of these is the best explanation of why that is?
The Earth is farther from the Sun during winter, so the days are shorter.
The Earth rotates faster on its axis during the winter, so the days are shorter.
The days are not shorter, it just appears so because of daylight saving time.
During winter the Northern Hemisphere is tilted away from the Sun, so the days are shorter.
Why do places near the equator have a warmer climate than places near the poles?
Locations near the equator have more solar wind exposure which causes longer summers.
Because of the tilt of the Earth, locations near the equator have more consistent direct sunlight year around than locations near the poles.
Locations near the equator are closer to the sun than locations near the poles because the equator sticks out farther from the Earth.
Places near the poles are colder than places near the equator because there are less clouds in the areas near the poles.
Using the image, which position is the Earth when it is summer in the Northern Hemisphere?
The Earth__________ on its axis and_____________around the sun.
revolves; rotates
orbits; rotates
rotates; revolves
orbits; revolves
Carefully observe the image. What event is taking place in each picture?
Crescent, Full moon, Waxing gibbous
Crescent, new moon, Waning gibbous
Partial Solar Eclipse, Annular Solar Eclipse, Total Solar Eclipse
Partial Lunar Eclipse, Annular Lunar Eclipse, Total lunar Eclipse
A tide has the most significant change in consecutive high and low tides.
spring
leap
autumn
neap
If Earth was suddenly removed from the solar system, what would happen to the moon?
the moon would fall towards Earth's former position.
the moon would move straight out of the solar system.
the moon would continue to move in its current orbit.
the moon would move into new orbit under the influence of the sun.
A neap tide is
a very extreme tide; when the moon, sun and Earth are in a straight line.
a normal tide; at any time during the moon's orbit.
a less extreme tide than normal; when Earth, moon and sun are in a straight line.
a less extreme tide than normal; when Earth, moon and sun form a right angle.
I cause tides, what am I?
Mental attraction
Gravitational attraction
Magnetic attraction
Planet attraction
When the part of the moon that you can see is slowly getting bigger, meaning its becoming more illuminated, we say that it is:
waning
gibbous
waxing
crescent
You notice there is an especially high tide on one day. It is higher than the tides on most other days of the year. What is the name of this tide, and what is probably causing this unusually high tide?
Spring tide, which is caused by Earth, moon, and sun all being in a straight line.
Neap tide, which is caused by Earth, moon, and sun all being in a straight line.
Neap tide, which is caused by Earth, moon, and sun all being in a right-angle triangle.
What are you talking about, that's probably a mistake in your eyesight.
True/false, two important things to look at when determining the phase of the moon are the side of the moon that is illuminated and the shape that is illuminated.
True
False
