b) Mercury has no atmosphere.

d)Mars and Venus have similar atmospheres.

e)Venus’s atmosphere is thick and contains clouds of sulfuric acid.

Explanation:

We have four innermost planets in the solar system and they are : Mercury, Mars, Venus and the Earth.

a) Mercury has no atmosphere: Mercury has a planet has no atmosphere because of its very small size. It is said that Mercury has a light or thin exosphere that is made up of gases such as hydrogen, helium, potassium, oxygen and sodium. This gases are found it very light quantity on Mercury.

Because Mercury has no atmosphere through which it can trap heat, the temperature on the planet can vary greatly,resulting very extreme temperatures. It can be very cold at night on Mercury and very hot in the morning i.e. -172°c at night to 427°c during the day.

b) Mars and Venus have similar atmospheres: When we compare the atmospheres on the Mars with that of the Venus, we can see some similarities. For example, Both Mars and Venus have 95% carbon dioxide present in their atmosphere.

c. Venus’s atmosphere is thick and contains clouds of sulfuric acid: This statement is very true. The atmospheres on Venus is very thick because it contains 95 % carbon dioxide. It also contains very thick clouds of sulphuric acid which makes the planet very hot and dry.

Due to this thick clouds, the amount of solar energy that Venus receives is lower than the amount of solar energy which the earth receives.
