1.
Which ones is NOT a celestial object?
Correct Answer
D. Humans
Explanation
Celestial objects are things that occur take up space in outer space. Humans take up space on Earth so it isn't considered a celestial object. Earth takes up space in the universe so it can be considered a celestial object.
2.
Day and night are caused by
Correct Answer
D. Earth's rotation on its axis.
Explanation
Day and night is caused by Earth's rotation on its axis. The tilt of Earth and Earth's revolution around the sun causes seasons.
3.
One complete revolution of Earth around the sun takes about
Correct Answer
C.
one year.
Explanation
It takes 365 days (or 1 year) for Earth to rotate around the sun once. In that time, there are 4 seasons.
4.
Earth has seasons because
Correct Answer
C.
Earth's axis is tilted as it moves around the sun.
Explanation
Earth is tilted on an axis, so different amounts of sunlight reaches Earth at different angles. This is what causes seasons to occur.
The distance between the Earth and Sun changes because Earth's orbit around the sun is an elliptical shape but that isn't the main cause of seasons.
5.
When the north end of Earth's axis is tilted toward the sun, North America will experience
Correct Answer
D.
more direct rays and longer days.
Explanation
Remember that the summer solstice occurs when the northern hemisphere of Earth is tilted towards the Sun. The direct rays causes longer and warmer days.
6.
In the Southern Hemisphere, the summer solstice occurs when the sun is shining on
Correct Answer
C. The southern hemispHere.
Explanation
The Tropic of Cancer is in the northern hemisphere. Remember when sunlight is directly on the southern hemisphere then that area will experience a summer solstice.
7.
An equinox occurs when
Correct Answer
A.
neither end of Earth's axis is tilted toward nor away from the sun.
Explanation
Equinox occur when Earth's axis is perpendicular to the sun's rays. Earth's axis is not tiled towards nor away from the sun. The axis is at a 90 degree angle to the sun's rays.
8.
Because the moon rotates once for each revolution around Earth
Correct Answer
C.
you never see the far side (opposite side) of the moon.
Explanation
You never see the far side of the moon (opposite side) because the moon rotates once for each revolution around Earth.
9.
The phase of the moon you see depends on
Correct Answer
B.
how much of the sunlit side of the moon faces Earth.
Explanation
The phase of the moon you see depends on how much of the sunlit side of the moon faces Earth. This is because the moon does not emit its own light, but rather reflects the sunlight. As the moon orbits around the Earth, the amount of the sunlit side that is visible from Earth changes, resulting in different phases of the moon. When the sunlit side is fully facing Earth, we see a full moon, and when none of the sunlit side is facing Earth, we see a new moon. The different phases, such as crescent, quarter, and gibbous, occur depending on the angle at which the sun's light hits the moon and how much of that illuminated side is visible from Earth.
10.
From new moon phase to full moon phase you see
Correct Answer
A.
an increasing amount of the lighted side of the moon.
Explanation
During the transition from the new moon phase to the full moon phase, the amount of the moon's lighted side that is visible from Earth gradually increases. This is because as the moon orbits around the Earth, the angle between the sun, Earth, and moon changes, causing different portions of the moon's surface to be illuminated. As the moon moves from the new moon phase to the full moon phase, more and more of the lighted side becomes visible, resulting in an increasing amount of the moon's lighted side being seen from Earth.
11.
For a solar eclipse to occur,
Correct Answer
B.
the moon must be directly between Earth and the sun.
Explanation
A solar eclipse occurs when the moon blocks sunlight and casts a shadow on Earth.
12.
During what phase can a lunar eclipse occur?
Correct Answer
D. Full moon
Explanation
Remember that a lunar eclipse occurs when the sun blocks the light of the moon. The entire moon is only visible during a full moon.
13.
You are less likely to see a solar eclipse than a lunar eclipse because
Correct Answer
D.
you must be in the moon's shadow to see a solar eclipse.
you must be in the moon's shadow to see a solar eclipse.
Explanation
The moon's shadow is much smaller than the Sun's shadow.
14.
Tides are caused mainly by
Correct Answer
D. Differences in how much the moon pulls on different parts of Earth.
Explanation
Tides are primarily caused by the gravitational pull of the moon on different parts of the Earth. The moon's gravitational force is stronger on the side of the Earth that is closer to it, causing a bulge in the ocean known as a high tide. On the opposite side of the Earth, there is also a high tide due to the moon's gravitational force pulling the Earth away from the water. This creates a second bulge in the ocean. As the Earth rotates, different parts of the planet experience these tidal bulges, resulting in the regular rise and fall of the tides.
15.
Most places on Earth experience
Correct Answer
C.
one high tide and one low tide about every 12.5 hours (almost half a day).
Explanation
There are usually 2 high tides and 2 low tides in about a day, so in about half a day there should be 1 low tide and 1 high tide.
16.
Galileo saw that much of the moon's surface is covered with round pits (holes) called
Correct Answer
C.
craters.
Explanation
Galileo observed that the moon's surface is filled with round pits, which are known as craters. These craters are formed due to the impact of meteoroids and other celestial bodies on the moon's surface. The presence of these craters indicates that the moon has undergone a history of intense bombardment from space debris. The other options, such as highlands, seas, and maria, do not accurately describe the round pits on the moon's surface.
17.
The force of friction pulls the moon and Earth toward each other. _________________________
Correct Answer
gravity
Explanation
Gravity is the force of attraction between two objects with mass. In the case of the moon and Earth, gravity is the force that pulls them towards each other. This gravitational force is responsible for keeping the moon in orbit around the Earth and also causes tides on Earth. Without the force of gravity, the moon and Earth would not be pulled towards each other, and their relationship would be completely different.
18.
The lighted half of the moon faces away from Earth during the ____________________ phase.
Correct Answer
new moon
Explanation
During the new moon phase, the moon is positioned between the Earth and the Sun. This means that the side of the moon that is illuminated by the Sun is facing away from Earth, making it appear as if there is no visible moon in the sky. This is why the lighted half of the moon faces away from Earth during the new moon phase.
19.
Any object that revolves around another object in space is called a ____________________.
Correct Answer
satellite
Explanation
A satellite is any object that revolves around another object in space. Satellites can be natural, such as moons, or artificial, such as man-made objects launched into orbit around the Earth. They are used for various purposes, including communication, weather monitoring, navigation, and scientific research. Satellites are essential for modern telecommunications and play a crucial role in providing services like global positioning systems (GPS) and satellite television.

Correct Answer
A. The high tides get lower and the low tides get higher.
Explanation
The high tides get lower and the low tides get higher.
On Monday, the first tide of the day was at 6:00AM and it was at 1.5m. (low tide)
On Thursday, the first tide of the day was at 12:30AM and it was at 6.1m. (higher)
This shows that the low tide got higher.
On Monday, the second tide of the day was at 2:00PM and it was at 6.7m. (high tide)
On Thursday, the second tide of the day was at 12:30AM and it was at 2.3m. (lower)
This shows that the high tide got lower.
On Monday, the third tide of the day was at 10:30PM and it was at 1.7m. (low tide)
On Thursday, the third tide of the day was at 12:00AM and it was at 5.9m. (higher)
This shows that the low tide got higher.
Therefore, the high tides get lower and the low tides get higher.

Explain how a lunar eclipse differs from a solar eclipse.
25.
Winds are caused by differences in
Correct Answer
C.
air pressure.
Explanation
Remember that air moves from an area of high air pressure to an area of low air pressure. Movement of air is called wind.
26.
Cool air masses tend to
Correct Answer
C. Falls and flow under warm air masses.
Explanation
Cool air masses tend to fall and flow under warm air masses because cool air is denser than warm air. This density difference causes the cool air to sink and flow beneath the warm air. As a result, the cool air displaces the warm air and creates a boundary between the two air masses. This phenomenon is known as subsidence, and it is a characteristic of stable atmospheric conditions.
27.
