Which characteristics make mercury different from earth? check all that apply. rings no moon slow revolution hot surface temperatures atmosphere of carbon dioxide

Earth and Mercury are different in their characteristics .

The first option is rings. Ring is not present in mercury. Earth also contains no rings around it.

The second option is moon. Mercury does not have any moon which will rotating around it. But earth has its own moon which is at 384000 km away from it.

The third option is the period of revolution. Mercury is closer to the sun as compared to earth. Hence its period of revolution around sun will be less than the period of revolution of earth. The period of revolution of earth is 365 days while it is only 88 days for mercury in earth days. Hence mercury has slow period of revolution.

As mercury is closer to the sun, its temperature varies between day and night. At night time, its temperature is below -173 degree celsius while during day time, its temperature is more than 477 degree celsius. Hence, mercury has high surface temperature as compared to earth.

The gravity of mercury is very less as compared to earth. So its atmosphere contains less amount of gaseous particles. The atmosphere of mercury contains hydrogen and helium,neon and carbon dioxide while earth atmosphere mainly contains nitrogen and oxygen. But mercury does not have  an atmosphere of carbon dioxide only. So this point is excluded.

No Moon, Hot surface temperatures

Explanation:

Both Mercury and Earth do not have rings. Mercury doesn't have a Moon like Earth. The reason for not having a Moon can be the closeness to the Sun.

Mercury is also known as planet of Extreme. This is because the it gest very hot during the daytime and very cold during night time. This happens because of the absence of atmosphere. Due to the absence of atmosphere the heat is not trapped inside. Earth has enough density of atmosphere thus maintaining perfect temperature for life survival.

it is b. absorbs thermal energy

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
