Which characteristic do Venus and Earth share?

a-same direction of rotation
b-similar size, mass, and density
c-slow revolution period around the Sun
d-atmosphere composed only of carbon dioxide


Sagot :

Answer: B

Explanation:

The characteristic that Venus and Earth share is:

b. similar size, mass, and density

Here’s an explanation for each option:

a. **Same direction of rotation**: This is not correct. Earth rotates on its axis from west to east, whereas Venus has a retrograde rotation, meaning it rotates from east to west.

b. **Similar size, mass, and density**: This is correct. Venus and Earth are often referred to as "sister planets" because they have similar sizes, masses, and densities.

c. **Slow revolution period around the Sun**: This is not correct. Both planets have relatively quick orbits around the Sun, with Venus taking about 225 Earth days and Earth taking about 365 days.

d. **Atmosphere composed only of carbon dioxide**: This is not correct. Venus's atmosphere is primarily composed of carbon dioxide (about 96.5%), but Earth's atmosphere is a mixture of nitrogen (about 78%), oxygen (about 21%), and other gases, including a very small amount of carbon dioxide.

Therefore, the correct answer is:

B. similar size, mass, and density
