1.
What does the earth's tilt cause?
Correct Answer
A. The seasons
Explanation
The tilt of the earth causes seasons to occur because it changes the angle that sun rays hit the earth
2.
What is the shape of the earth's orbit around the sun?
Correct Answer
B. Elliptical (slightly oval)
Explanation
Square? Are you kidding me!! It also does not change over time or for any other reason. If the earth were knocked out of its orbit or the orbit were to change, there would be major bad consequences for life on earth. Elliptical or oval is the correct answer.
3.
Which of the following best describes the tilt of the earth during the spring and fall equinoxes?
Correct Answer
B. The earth is tilted neither toward or away from the sun (tilt is side to side)
Explanation
During the spring and fall, the earth is tilted side to side as opposed to summer when that hemisphere is tilted toward the sun or away for winter
4.
Which of the following best describes the tilt of the earth when it is summer in the southern hemisphere?
Correct Answer
B. The northern hemispHere is tilted away from the sun
Explanation
when the northern hemisphere is tilted away from the sun, that means that the southern hemisphere is tilted toward the sun. When a hemisphere is tilted toward the sun, that means summer. OR When we have winter, they have summer.
5.
What effect does the tilt of the earth have?
Correct Answer
A. It changes the angle that the sun strikes the earth in different land areas
Explanation
The more directly the sun's rays strike the earth, the more effective it is at warming the earth. The sun's rays strike the equator directly year round and so it is always warm at the equator.
6.
Which of the following best describes equinoxes?
Correct Answer
A. The earth is tilted neither toward or away from the sun
Explanation
Equinox-think equal. Equal amounts of day and night. In order for that to happen, the tilt must be side to side, otherwise, one hemisphere would receive more (or less) direct sunlight
7.
Which of the following best describes solstice.
Correct Answer
D. All of the above
Explanation
A solstice occurs when the earth is at its greatest tilt either toward or away from the sun. In the Northern hemisphere Winter solstice is in December and the summer solstice is in June
8.
The Arctic Circle receives several days each year where the sun never rises.
Correct Answer
A. True
Explanation
The winter solstice for the northern hemisphere will yield several days where the sun never rises. This is due to the tilt of the earth
9.
Each day past the summer solstice, the days get longer and longer until the fall equinox.
Correct Answer
B. False
Explanation
The days get shorter. As we progress from summer to fall, the days get shorter until we have equal amounts of day and night at the equinox. Days will continue to get shorter until the winter solstice.
10.
It takes approximately one _________ for Earth to make one revolution around the Sun.
Correct Answer
year
Explanation
The correct answer is "year" because a year is the unit of time that represents the period it takes for Earth to complete one full revolution around the Sun. This is commonly known as a solar year and is approximately 365.25 days long.
11.
Earth moves around the Sun because of the pull of gravity between Earth and the
Sun.
Correct Answer
A. True
Explanation
The explanation for the given correct answer is that the force of gravity between the Earth and the Sun is what keeps the Earth in its orbit around the Sun. Gravity is a fundamental force in the universe that attracts objects towards each other. In the case of the Earth and the Sun, the Sun's massive size and gravitational pull keep the Earth in a stable orbit, preventing it from drifting off into space. This gravitational force is what causes the Earth to move around the Sun.
12.
The force of gravity between two objects depends on the _______ and the _________ of the objects.
Correct Answer
B. Mass and distance
Explanation
The force of gravity between two objects depends on the mass of the objects, which refers to the amount of matter in each object. The greater the mass, the stronger the gravitational force. Additionally, the force of gravity also depends on the distance between the objects. The farther apart the objects are, the weaker the gravitational force between them. Therefore, the correct answer is mass and distance.
13.
Earth’s rotation makes the Sun appear to rise in the __________.
Correct Answer
east
Explanation
The Earth's rotation causes the Sun to appear to rise in the east. As the Earth spins on its axis from west to east, it creates the illusion that the Sun is moving across the sky from east to west. This is why we see the Sun rise in the east and set in the west.
14.
____________ is the movement of one object around another object.
Correct Answer
B. Revolution
Explanation
The correct answer is "Revolution" because it refers to the movement of one object around another object. This term is commonly used in astronomy to describe the motion of planets around the sun or moons around a planet. Rotation, on the other hand, refers to the spinning or turning of an object around its own axis. Orbit is a term used to describe the path an object takes as it revolves around another object.
15.
The __________ diameter is more than 100 times greater than Earth’s diameter.
Correct Answer
sun
sun's
Explanation
The correct answer is "sun". The sun's diameter is more than 100 times greater than Earth's diameter. This is because the sun is a massive star, much larger than our planet. Its diameter is approximately 109 times that of Earth, making it significantly larger in size.
16.
The path a revolving object follows is its ____________.
Correct Answer
A. Orbit
Explanation
The path a revolving object follows is called its orbit. An orbit refers to the curved path that an object takes around a larger object, typically due to gravitational forces. This term is commonly used in the context of celestial bodies, such as planets orbiting around the sun or moons orbiting around a planet. It is important to note that orbit specifically implies a curved trajectory, distinguishing it from the other options provided.
17.
The earth is a tilted planet. What is the degree of tilt?
Correct Answer
C. 23.5 degrees
Explanation
Most of the planets have a similar tilt, except Neptune.
18.
____________ is the movement of one object around another object.
Correct Answer
B. Revolution
Explanation
We, like ALL planets, do this around the Sun. Our Moon does this to us.
19.
The path a revolving object follows is its ____________.
Correct Answer
A. Orbit
Explanation
Ours is elliptical, lip an oval or egg.
20.
____________ is the movement of one object around another object.
Correct Answer
B. Revolution
Explanation
Revolution is the correct answer because it refers to the movement of one object around another object. In this context, revolution typically describes the motion of celestial bodies, such as planets, around the sun. Rotation, on the other hand, refers to the spinning motion of an object around its own axis. Orbit is a term related to revolution, as it describes the path an object takes around another object due to gravitational forces.
