Questions and Answers

1.

The Ancient Greeks such as Aristotle and Ptolemy believed that
- A.
  
  The Earth is the center of the universe
- B.
  
  The Sun is the center of the unverse
Correct Answer
A. The Earth is the center of the universe

Explanation
The explanation for the given correct answer is that the Ancient Greeks, including Aristotle and Ptolemy, believed in a geocentric model of the universe, which states that the Earth is at the center. This belief was based on their observations of celestial bodies and the apparent motion of the Sun, Moon, and planets across the sky. They proposed a system where the Earth was stationary and all other celestial bodies revolved around it. This geocentric model prevailed for centuries until it was later challenged by the heliocentric model proposed by Copernicus and supported by later scientific discoveries.

2.

This ancient Greek Astronomer influenced Copernicus to theorize the Heliocentric Solar System.
- A.
  
  Martin Luther
- B.
  
  Kepler
- C.
  
  Ptolemy
Correct Answer
C. Ptolemy

Explanation
Ptolemy was an ancient Greek astronomer who greatly influenced Copernicus to theorize the Heliocentric Solar System. Ptolemy's geocentric model of the universe, known as the Ptolemaic system, placed the Earth at the center and the other celestial bodies revolving around it. Copernicus studied Ptolemy's work and eventually developed his own heliocentric model, which placed the Sun at the center of the solar system. Therefore, Ptolemy's theories and ideas played a significant role in inspiring Copernicus to formulate the concept of a heliocentric solar system.

Johannes Kepler removed the Earth as the center of the universe to create his Theory of the Heliocentric Model.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Johannes Kepler did not remove the Earth as the center of the universe to create his Theory of the Heliocentric Model. In fact, it was Nicolaus Copernicus who proposed the heliocentric model, which placed the Sun at the center of the universe. Kepler, on the other hand, built upon Copernicus' work and developed his own laws of planetary motion, which described the elliptical orbits of the planets around the Sun.

4.

Kepler said that the planets orbits the sun in ___________ motions rather than in perfect circles.

Correct Answer
oval
elliptical

Explanation
Kepler proposed that the planets orbit the sun in elliptical motions instead of perfect circles. This means that the shape of their orbits is not a perfect oval, but rather a slightly elongated oval shape. This discovery was a significant breakthrough in understanding the nature of planetary motion and helped to refine our understanding of the solar system.

_________________ proposed that motions of objects were controlled or governed by 3 laws of Motion.
- A.
  
  Copernicus
- B.
  
  Einstein
- C.
  
  Sir Isaac Newton
Correct Answer
C. Sir Isaac Newton

Explanation
Sir Isaac Newton proposed that motions of objects were controlled or governed by 3 laws of Motion. Newton's laws of motion describe the relationship between the motion of an object and the forces acting upon it. These laws are fundamental principles in the field of physics and have been widely accepted and used for centuries. Newton's laws of motion revolutionized the understanding of motion and laid the foundation for classical mechanics.

What celestial body is responsible for the tides on the Earth?
- A.
  
  Sun
- B.
  
  Stars
- C.
  
  Moon
Correct Answer
C. Moon

Explanation
The Moon is responsible for the tides on Earth due to its gravitational pull. The Moon's gravity causes the water on Earth to bulge towards it, creating high tides. As the Earth rotates, different parts of the planet experience these high tides. The gravitational force of the Moon also causes a second bulge on the opposite side of the Earth, resulting in low tides. The Sun also has an influence on tides, but its effect is about half as strong as the Moon's.

What is reponsible for night and day on Earth?
- A.
  
  The 23 degree angle of the north and south poles
- B.
  
  The movement of Earth on its axis
- C.
  
  The revolution around the sun.
Correct Answer
B. The movement of Earth on its axis

Explanation
The movement of Earth on its axis is responsible for night and day on Earth. As Earth rotates on its axis, different parts of the planet are either facing towards or away from the sun, causing the alternation between day and night. This rotation takes approximately 24 hours to complete, resulting in a full day-night cycle. The 23-degree angle of the north and south poles and the revolution around the sun also have significant effects on Earth's seasons and the length of daylight, but they are not directly responsible for the occurrence of night and day.

8.

What movement of the Earth gives us our yearly calendar?
- A.
  
  The movement of the earth on its axis
- B.
  
  The revolution around the Sun
- C.
  
  The monthly movement of the moon around the earth
Correct Answer
B. The revolution around the Sun

Explanation
The movement of the Earth around the Sun is what gives us our yearly calendar. This revolution takes approximately 365.25 days to complete, resulting in the length of a year. This movement is responsible for the changing seasons and the different positions of the Sun in the sky throughout the year. The Earth's rotation on its axis, on the other hand, gives us the day and night cycle. The monthly movement of the moon around the Earth is unrelated to the yearly calendar.

This 20th Century Scientist was a great thinker. His THEORY OF RELATIVITY theorized that time travel was possible
- A.
  
  Edwin Hubble
- B.
  
  Albert Einstein
- C.
  
  Stephen Hawking
Correct Answer
B. Albert Einstein

Explanation
Albert Einstein is the correct answer because he was a renowned scientist in the 20th century and is widely known for his theory of relativity. His theory revolutionized our understanding of space, time, and gravity, and one of the implications of his theory is the possibility of time travel. Einstein's work has had a profound impact on the field of physics and his contributions continue to be influential in scientific research today.

RED Shift is 1 bit of evidence that the universe is expanding and that the galaxies are moving away from each other.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The red shift refers to the phenomenon where light from distant galaxies is shifted towards the red end of the spectrum, indicating that the galaxies are moving away from us. This observation supports the idea that the universe is expanding, as if everything is moving away from a central point. Therefore, the statement that the red shift is evidence for the expansion of the universe and the movement of galaxies away from each other is true.
