A sudden, violent movement of electrons.
- A.
Thunder
- B.
Electrons
- C.
Lightning
- D.
Electricity
Correct Answer
C. LightningExplanation
Lightning is a sudden, violent movement of electrons. During a thunderstorm, the buildup of electrical charges in the atmosphere causes a discharge of electricity in the form of a lightning bolt. This discharge occurs when there is a difference in electrical potential between the ground and the clouds, causing a rapid movement of electrons. The movement of these electrons creates a bright flash of light and the characteristic sound of thunder. Therefore, lightning is the correct answer as it accurately describes the sudden, violent movement of electrons.Rate this question:

A single bolt of lightning is hotter than the surface of the sun.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A single bolt of lightning is hotter than the surface of the sun because lightning can reach temperatures of around 30,000 Kelvin (53,540 degrees Fahrenheit), while the surface of the sun has an average temperature of about 5,500 degrees Celsius (9,932 degrees Fahrenheit). Lightning is formed by the movement of electrons and ions, which generates intense heat and causes the surrounding air to rapidly expand, resulting in the characteristic thunder sound.Rate this question:

What causes lightning?
- A.
When the natural electricity in the cloud is out of balance.
- B.
Ice crystals ad water droplets swirl around each other, water droplets are blown up to the top of the cloud where it is very cold and create hailstones. The hailstones fall and crash into each other and creates a negative electrical charge. The top cloud, the smaller ice crystals are left with a positive electrical charge.
- C.
The negatively charged electrons in the bottom of the cloud are pulled toward the positively charged particles in the top of the cloud.
- D.
All of the above.
Correct Answer
D. All of the above.Explanation
The explanation for the given correct answer, "All of the above," is that lightning is caused by a combination of factors. When the natural electricity in the cloud is out of balance, it creates a situation where ice crystals and water droplets swirl around each other. The water droplets are blown up to the top of the cloud where it is very cold and create hailstones. As the hailstones fall and crash into each other, they create a negative electrical charge. At the same time, the smaller ice crystals in the top of the cloud are left with a positive electrical charge. The negatively charged electrons in the bottom of the cloud are then pulled toward the positively charged particles in the top of the cloud, resulting in lightning.Rate this question:

A single bolt of lightning might be several miles long and contain how many electrons?
- A.
156 million
- B.
156 quintillion
- C.
156 billion
- D.
None of the above
Correct Answer
B. 156 quintillionExplanation
A single bolt of lightning can be several miles long and is a powerful discharge of electricity. Electrons are the negatively charged particles that carry the current in an electrical circuit. Given the magnitude and intensity of a lightning bolt, it is reasonable to assume that it contains a massive number of electrons. Therefore, the correct answer is 156 quintillion, which represents an extremely large quantity of electrons.Rate this question:

Lightning helps restore the natural electrical balance in the clouds.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Lightning helps restore the natural electrical balance in the clouds by transferring electrical charges between the ground and the clouds. During a thunderstorm, the buildup of electrical charges in the clouds is discharged through lightning bolts, which travel from the negatively charged bottom of the cloud to the positively charged ground. This process helps to equalize the electrical imbalances in the atmosphere, restoring a more stable state. Therefore, the statement that lightning helps restore the natural electrical balance in the clouds is true.Rate this question:

Where is the best place to be during a thunderstorm?
- A.
Under a tree
- B.
Inside a car
- C.
Inside a building
- D.
Both B and C
Correct Answer
D. Both B and CExplanation
During a thunderstorm, it is unsafe to be outside, as lightning can strike objects such as trees. Being inside a car or a building provides protection from lightning strikes, as they act as a Faraday cage, directing the electric charge around the occupants and into the ground. Therefore, the best place to be during a thunderstorm is either inside a car or inside a building.Rate this question:

This type of lightning is the most dangerous.
- A.
When a netrual electrical charge builds up on the ground it makes the electrons in the thundercloud discharge into the sun.
- B.
When a negative electrical charge builds up on the ground it makes the electrons in the thundercloud discharge into the earth.
- C.
When a positive electrical charge builds up on the ground it makes the electrons in the thundercloud discharge into the earth.
Correct Answer
C. When a positive electrical charge builds up on the ground it makes the electrons in the thundercloud discharge into the earth.Explanation
When a positive electrical charge builds up on the ground, it creates an imbalance with the negative charge in the thundercloud. This imbalance causes the electrons in the thundercloud to be attracted to the positively charged ground, resulting in a discharge of lightning from the cloud to the earth. This type of lightning is considered the most dangerous because it carries a high amount of energy and can cause significant damage.Rate this question:
-
- 13.
Lightning never strikes the same place twice.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false because lightning can strike the same place multiple times. Tall buildings, trees, and other high structures are often struck by lightning repeatedly. Additionally, lightning can strike the same area during a thunderstorm, as the electrical charge may be attracted to the same location due to various factors such as topography or conductivity of the ground. Therefore, it is incorrect to say that lightning never strikes the same place twice.Rate this question:

- C.
Downward Steamer
- D.
Upward Streamer
Correct Answer
D. Upward StreamerExplanation
When the stepped leader, a channel of negative charge, gets closer to the ground, it induces a stream of positively charged particles to rise upwards. This rising stream of positive charges is known as an upward streamer. The upward streamer and the stepped leader connect, completing the path for the lightning discharge to occur.Rate this question:
-
- 17.
What is formed when an Upward Streamer and a Stepped Leader meet?
- A.
Lightning Channel
- B.
Thunder and Lightning Channel
- C.
Thunder Channel.
Correct Answer
A. Lightning ChannelExplanation
When an Upward Streamer and a Stepped Leader meet, they form a Lightning Channel. This channel is the path through which the electrical discharge of a lightning bolt travels. It is created when the negatively charged stepped leader from the cloud connects with the positively charged upward streamer from the ground. The lightning channel allows for the flow of electricity, resulting in the bright flash of lightning that we see during a thunderstorm.Rate this question:
