What color is Mercurys sky?
The sky on Mercury appears black during the day due to the lack of significant atmosphere to scatter sunlight and create the typical blue color we see on Earth. At sunrise and sunset, the sky can take on a bluish hue due to the scattering of light by the dust and gas in Mercury's thin atmosphere.
What might the surface temperature be like on a planet with no atmosphere?
It depends on how far away the planet is from a star. If it's close, it's hot. Also, if the planet rotates on its axis there would be a big day-night temperature difference.
Why does the earth remain warm after sunset?
The surface of the earth holds heat, and the greenhouse gases in the atmosphere hold heat all through the night. If the earth had no atmosphere, then at night all the heat would escape out to space and the earth would be freezing.
The earth without atmhophere?
The Earth without atmosphere would alternate between boiling and freezing (day and night). It would be bombarded with dangerous levels of UV radiation. Meteorites would rain down from the sky without burning up on a daily basis.
What is is mercurys temperature?
Approximately -184 degrees facing away from the sun and about 427 degrees facing the sun, we do not have an accurate temperature because if an astronaut was to land on Mercury, he would drop dead when he gets 80 miles close to Mercury.
If the earth did not have an atmosphere temperature extremes between day and night?
Without an atmosphere, there would be significant temperature extremes between day and night. During the day, the surface would become very hot due to direct sunlight, while at night, temperatures would drop rapidly without the atmosphere to trap heat. This difference is significant because the atmosphere helps regulate temperature by trapping heat and distributing it around the planet.
What would happen if there would be no atmosphere?
If there was no atmosphere, there would be no air for us to breathe, leading to suffocation and the inability for life to exist on Earth. Additionally, the lack of atmosphere would result in extreme temperature fluctuations between day and night, and increased exposure to harmful solar radiation.
If there is no atmosphere what wwill be temp extreme bw day n night?
Without an atmosphere to distribute heat, temperature extremes between day and night on a celestial body would be significant. During the day, the surface exposed to the sun's rays would become extremely hot, while at night, without an atmosphere to trap heat, temperatures would plummet drastically. This phenomenon is observed on the moon, where temperatures range from about 127 degrees Celsius during the day to around -173 degrees Celsius at night.
The role of atmosphere in climate control?
The atmosphere prevents the sudden increase in temperature during the daylight hours. And during the night, it slows down the escape of heat into outer space. +++ It would be more accurate and more to the point to state that without the atmosphere there would be no climate!
What is the planet mercurys atmosphere made of?
Mercury has a surface pressure that is near enough zero (or a vacuum), the planet holds no real atmosphere due to its small size. There are some trace gases at the surface, but not what one would call a proper atmosphere.
What would happen if there is were no atmosphere on the earth?
If there were no atmosphere on Earth, there would be no air for humans and most living creatures to breathe. The lack of atmosphere would also lead to extreme temperature fluctuations between day and night, and increased exposure to harmful solar radiation. Additionally, without the atmosphere, there would be no protection against meteoroids and space debris, making life on Earth unsustainable.
What color is Mercurys sky?
The sky on Mercury appears black during the day due to the lack of significant atmosphere to scatter sunlight and create the typical blue color we see on Earth. At sunrise and sunset, the sky can take on a bluish hue due to the scattering of light by the dust and gas in Mercury's thin atmosphere.
How might the earth be different without the atmosphere?
Without an atmosphere, Earth would be much colder as there would be no greenhouse effect to trap heat. There would be no protection from harmful cosmic rays and meteoroids, making life as we know it impossible. The lack of atmosphere would also result in extreme temperature differences between day and night.
What might the surface temperature be like on a planet with no atmosphere?
It depends on how far away the planet is from a star. If it's close, it's hot. Also, if the planet rotates on its axis there would be a big day-night temperature difference.
What is the temperature of night on Saturn?
Saturn is the gas Giant with tiny core deep down the atmosphere. Surface temperature of Saturn is govern by its' thermodynamic cycle of rise and sink of massive gases. I believe, the surface temperature at the reference surface would not be of any great difference may be 10,000 oC with insignificant difference of day and night.
Why does the earth remain warm after sunset?
The surface of the earth holds heat, and the greenhouse gases in the atmosphere hold heat all through the night. If the earth had no atmosphere, then at night all the heat would escape out to space and the earth would be freezing.
