Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mercury is the planet closest to the Sun. It has frozen water on its poles, and it has an extremely thin atmosphere. During the day, the temperature reaches 850
A
No, because the temperatures are too extreme.
B
Yes, because Mercury has water and sunlight.
C
No, because life can only exist in the place where it first evolved.
D
Yes, because Mercury has an atmosphere
Explanation: 

Detailed explanation-1: -Mercury is the closest planet to the Sun. Its orbit around the Sun is very elliptical, like a stretched out circle, compared to those of the other planets. Mercury’s distance from the Sun ranges from 28.6 million miles (46 million km) to 43.4 million miles (69.8 million km).

Detailed explanation-2: -The heat from our star actually contributes to the formation of ice, according to a paper published in The Astrophysical Journal Letters on Monday. Mercury’s surface can get up to 400 degrees Celsius (752 degrees Fahrenheit) during daytime, a temperature that doesn’t support liquid water let alone ice.

Detailed explanation-3: -Because the planet has no atmosphere to retain that heat, nighttime temperatures on the surface can drop to minus 290 degrees Fahrenheit (minus 180 degrees Celsius). Mercury may have water ice at its north and south poles inside deep craters, but only in regions in permanent shadows.

Detailed explanation-4: -Because Mercury does not have a substantial atmosphere to transport heat around the planet, the darkness allows ice to remain frozen despite the extreme temperatures of the tiny world.

Detailed explanation-5: -Tough Place for Life It is unlikely that life as we know it could survive on Mercury due to solar radiation, and extreme temperatures.
