Test Your Knowledge Of Science: 1 In 4 People Fail This Quiz! - Quiz

This is a copy of the National Science Foundation's simple quiz regarding scientific knowledge in the United States. 1 in 4 people fail this test. This is why Bill Nye "The Science Guy" recently warned Americans that we risk losing our place in the world market. Take the quiz and see how you do.

Questions and Answers

1.

The center of the Earth is very hot. True or false?
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The center of the Earth is indeed very hot. This is because of the intense pressure caused by the layers of rock and metal above it, which generate a tremendous amount of heat. The Earth's core is primarily made up of molten iron and nickel, and temperatures there can reach up to 5700 degrees Celsius (10,000 degrees Fahrenheit). This extreme heat is responsible for driving geological processes such as plate tectonics and the creation of Earth's magnetic field.

2.

The continents have been moving their location for millions of years and will continue to move. True or false?
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement is true because the continents on Earth are constantly moving due to the process of plate tectonics. Over millions of years, the plates that make up the Earth's surface shift and collide, causing the continents to move and change their location. This movement is responsible for various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges. Therefore, the continents have indeed been moving their location for millions of years and will continue to do so in the future.

3.

All radioactivity is man-made. True or false?
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false because radioactivity can occur naturally. Radioactive elements such as uranium, radon, and thorium are present in the Earth's crust, and radioactive decay processes also occur naturally. Additionally, natural sources of radiation include cosmic rays from space and radiation from the sun. Therefore, not all radioactivity is man-made.

Rate this question:
4.

Does the Earth go around the sun, or does the sun go around the Earth?
- A.
  
  The Earth goes around the sun.
- B.
  
  The sun goes around the Earth.
Correct Answer
A. The Earth goes around the sun.

Explanation
The correct answer is that the Earth goes around the sun. This is based on the heliocentric model of the solar system, which was developed by Nicolaus Copernicus and supported by subsequent scientific evidence. According to this model, the sun is at the center of the solar system and the planets, including Earth, orbit around it. This understanding is supported by observations of the motion of celestial bodies and has been widely accepted in the scientific community for centuries.

Rate this question:
5.

Electrons are smaller than atoms. True or false?
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Electrons are subatomic particles that orbit around the nucleus of an atom. They have a much smaller size compared to atoms, which consist of a nucleus (containing protons and neutrons) and electrons. Therefore, it is true that electrons are smaller than atoms.

6.

Lasers work by focusing sound waves. True or false?
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Lasers do not work by focusing sound waves. Instead, lasers work by focusing and amplifying light waves through a process called stimulated emission. This allows for the production of a highly concentrated and coherent beam of light.

Rate this question:
7.

The universe began with a huge explosion. True or false?
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The correct answer is True. This is based on the scientific theory known as the Big Bang, which suggests that the universe originated from a dense and hot state around 13.8 billion years ago. This theory is supported by various pieces of evidence, such as the observed expansion of the universe and the detection of cosmic microwave background radiation.

8.

It's the father's gene that decides whether the baby is a boy or girl. True or false?
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement is true because the sex of a baby is determined by the father's genes. The father contributes either an X or a Y chromosome, while the mother always contributes an X chromosome. If the father's sperm carries an X chromosome, the baby will be a girl (XX), and if the father's sperm carries a Y chromosome, the baby will be a boy (XY). Therefore, the father's genes play a crucial role in determining the sex of the baby.

Rate this question:
9.

Antibiotics kill viruses as well as bacteria. True or false?
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Antibiotics are specifically designed to kill bacteria, not viruses. Viruses are different from bacteria in terms of their structure and way of replication. Antibiotics work by targeting specific structures or processes that are unique to bacteria, such as their cell walls or protein synthesis. Since viruses lack these specific targets, antibiotics are ineffective against them. To treat viral infections, antiviral medications are used instead. Therefore, the statement "Antibiotics kill viruses as well as bacteria" is false.

10.

Human beings, as we know them today, developed from earlier species of animals. True or false?
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Human beings have evolved from earlier species of animals through a process known as biological evolution. This process involves the gradual changes in genetic traits over generations, leading to the development of new species. Fossil records, comparative anatomy, and genetic evidence all support the theory of human evolution. Therefore, it is true that human beings have developed from earlier species of animals.
