1.
What is another name for the Northern Lights?
Correct Answer
C. Aurora borealis
Explanation
The correct answer is "Aurora borealis". The Northern Lights, also known as Aurora borealis, are a natural light display that occurs in the polar regions. This phenomenon is caused by the interaction between charged particles from the sun and the Earth's magnetic field. The lights are typically seen in the northern hemisphere, but can also occur in the southern hemisphere, where they are known as the Southern Lights or Aurora australis.
2.
Where are the Northern Lights happen to be seen out of the following?
Correct Answer
A. Alaska
Explanation
The Northern Lights, also known as the Aurora Borealis, are a natural phenomenon that occurs in the Earth's polar regions. They are caused by the interaction of charged particles from the sun with the Earth's magnetic field. Alaska is located in the northernmost part of the United States and is known for its prime viewing locations for the Northern Lights. On the other hand, New Jersey and Zimbabwe are located far away from the polar regions and are not typically associated with sightings of the Northern Lights.
3.
The lights are caused by _________ electrically charged particles interacting with the Earth magnetic field.
Correct Answer
B. Solar Winds
Explanation
Solar winds are streams of charged particles, mainly electrons and protons, emitted by the Sun. When these charged particles interact with the Earth's magnetic field, they can cause the phenomenon known as the Northern Lights or Aurora Borealis. The charged particles from the solar winds excite the atoms and molecules in the Earth's atmosphere, causing them to emit light. Therefore, the lights mentioned in the question are caused by solar winds interacting with the Earth's magnetic field.
4.
What is the most common color of the Northern Lights?
Correct Answer
C. Green
Explanation
The most common color of the Northern Lights is green. This is because the green color is produced when charged particles from the sun collide with atoms and molecules in the Earth's atmosphere, specifically with oxygen atoms. These collisions cause the oxygen atoms to emit green light, resulting in the vibrant green color that is often associated with the Northern Lights.
5.
It can be up to _____ miles wide.
Correct Answer
B. 2,000
Explanation
The given statement suggests that "it" can be up to 2,000 miles wide.
6.

7.
Borealis is named after the Greek God of the ____.
Correct Answer
C. Northern Wind
Explanation
Borealis is named after the Greek God of the Northern Wind. In Greek mythology, Boreas was the personification of the cold north wind, often depicted as a bearded man with wings, blowing gusts of cold air. The term "Borealis" is commonly used to refer to the Northern Lights, a natural phenomenon that occurs in the northern hemisphere due to the interaction of solar particles with the Earth's magnetic field. The name "Borealis" is fitting as it represents the connection between the Greek God of the Northern Wind and the awe-inspiring beauty of the Northern Lights.
8.
One last question, Let's move to the South. What are the Southern lights called scientifically?
Correct Answer
A. Aurora Australis
Explanation
The Southern lights are scientifically called Aurora Australis. This natural phenomenon occurs in the Southern Hemisphere, similar to the Northern lights (Aurora Borealis) in the Northern Hemisphere. The lights are caused by the interaction of charged particles from the sun with the Earth's magnetic field, creating colorful displays of light in the sky.
