Because we have a thick atmosphere that is warmed by the sun during the day.
Plus the moon is dead, it does not have a moltern core like the earth which means still cooler temperatures.
If Earth had no tilt, there would be no seasons as we experience them now. This tilt is what causes variations in temperature and daylight throughout the year, leading to distinct seasons. Without it, much of the planet would have consistent weather patterns and temperatures.
If the Earth's rotation axis had no inclination, there would be no variation in the angle at which sunlight hits different parts of the Earth's surface, resulting in no distinct seasons. Areas at the equator would experience consistent temperatures year-round, while areas closer to the poles would have milder but less distinct seasonal changes.
It firstly depends how slow,as slower it rotates bigger the difference of daily temperatures especially around Equator,where most of the cyclones are formed. Always slower rotation would mean the cyclones of unprecedented strengths and unpredictability.
If Earth's axis were perpendicular to its orbital plane (i.e., the axis of rotation were upright), there would be no change in the Earth's relationship with the Sun. However, this change would eliminate the seasons as we know them, leading to more consistent temperatures around the world. Climate patterns and biodiversity could also be greatly affected as a result.
If the Earth's tilt was suddenly corrected, the North and South Poles would experience more consistent sunlight and temperatures throughout the year. This would disrupt the climate patterns in those regions and likely lead to significant changes in weather, ice coverage, and ecosystems.
If Earth's axis was tilted at 60 degrees, the planet's seasons would be much more extreme than they are currently. The poles would experience long periods of daylight and darkness, while the equatorial regions would have more consistent temperatures throughout the year. This extreme tilt would likely lead to significant changes in weather patterns and ecosystems across the globe.
If the sun were closer, Earth would be too hot for life to survive, as temperatures would be too high. If the sun were farther away, Earth would be too cold for life to exist, as temperatures would be too low. The distance between Earth and the sun is crucial for maintaining the ideal conditions for life.
About 3 Kelvin (-270 oC)
Yes it would.
If Earth had a thinner atmosphere, it would lead to less heat being trapped near the surface, resulting in faster cooling at night. This would likely cause average nighttime temperatures to drop more quickly and be colder compared to what we experience with our current atmosphere.
We would die because the temperatures would be to hot for life to take place.
Such high temperatures would not be found naturally on Earth. These extreme temperatures are typically associated with industrial processes, such as in certain types of furnaces or laboratory experiments. In nature, the hottest temperatures are found in phenomena like volcanic eruptions, but they are not in the range you mentioned.
