Question

Which characteristics do Venus and Earth share?
A. similar size, mass and density
B. same direction of rotation
C. slow revolution period around the Sun
D. atmosphere composed only of carbon dioxide.

Answer 1

Hint:There are eight planets in the solar system – Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Venus is usually called the Earth’s twin because of many similarities between them.Venus is only 30% closer to the Sun than Earth.They share similar size, and an atmosphere with a complex weather system.They have the same density.There are many differences between both the planets as well. The rotation time period, density of atmosphere, chemical composition of the atmosphere.Using this information, we will solve the above question.

Complete step by step answer:
Venus is also known as Earth’s twin because of many similarities they share. But they are not exactly alike. Earth takes 24 hours to rotate around the sun whereas Venus takes 243 days, the rotation of Venus is known as retrograde rotation. The orbital period of Venus is 225 days. This is the reason why Venus lasts less than a full day.

Earth and Venus have similar size, mass and density. They also have a very similar composition. But there is a difference in the composition of atmospheres. The atmosphere of Venus is only composed mostly of carbon dioxide and a little bit of nitrogen. The atmosphere of Venus is 90% denser than that of the Earth. Venus is the most reflecting body in the solar system.

Therefore, the right option would be A.

Note:Having a thorough knowledge about the composition and characteristics of both Earth and Venus will help us solve the question. Even though Venus is named as Earth’s twin, there are many differences between them. We should not have a misconception that they are very similar and do not have any differences.
