3. Question
Which of the following statements regarding planet Venus are correct?
1. Venus is the second planet from the Sun
2. In Venus, the Sun rises in the east and sets in the west.
Select the correct answer using the code below.CorrectAnswer: A
• Venus is the second planet from the Sun and as the brightest natural object in Earth’s night sky after the Moon, Venus can cast shadows and can be, on rare occasions, visible to the naked eye in broad daylight.
• In Venus, the Sun rises in the west and sets in the east, because it rotates in the opposite direction (East to West/Clockwise) to all but Uranus.
• It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. Because of this, the greenhouse effect on Venus is so strong that even though Mercury is closer to the Sun, Venus has the hottest surface of any planet in the Solar System.
• The atmospheric pressure at the planet’s surface is about 92 times the sea level pressure of Earth.
• Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.
• The water has probably photo dissociated, and the free hydrogen has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.
• As one of the brightest objects in the sky, Venus has been a major fixture in human culture for as long as records have existed.IncorrectAnswer: A
