If there was no sun, the temperature on Earth would be extremely cold, likely well below freezing. The sun provides heat and light to our planet, so without it, the Earth would quickly become uninhabitable for most forms of life.

How is the temperature on mercury be different if it the same mass as earth?

If Mercury had the same mass as Earth, its temperature would still be higher due to its proximity to the Sun, lack of atmosphere to regulate temperature, and slow rotation causing extreme temperature differences between the day and night sides. The mass of a planet does not significantly influence its surface temperature compared to factors like distance from the sun and atmospheric composition.


Why the earth is not in thermal equilibrium with yhe sun?

The Earth is not in thermal equilibrium with the Sun because the Earth receives energy from the Sun in the form of sunlight but also radiates energy back into space in the form of infrared radiation. This continuous exchange of energy maintains a temperature difference between the Earth and the Sun, preventing thermal equilibrium. Additionally, factors such as the Earth's atmosphere, albedo, and distance from the Sun also contribute to the lack of thermal equilibrium.


What would happen if the sun suddenly turned into a black hole?

If the sun were to suddenly turn into a black hole, it would not affect Earth's orbit or cause it to be sucked in. However, the lack of sunlight would lead to a rapid drop in temperature, causing all life on Earth to perish.


Why does the surface temperature of Earth usually decrease at night after the sun sets?

The surface temperature of Earth usually decreases at night after the sun sets because there is no sunlight to provide warmth through radiation, causing the Earth's surface to lose heat to the atmosphere.


What would happen if gravity were not a force acting between Earth and the sun?

If gravity were not a force between Earth and the sun, Earth would move in a straight line tangential to its orbit instead of orbiting around the sun. This would cause Earth to drift off into space, no longer held in orbit by the sun's gravitational pull.

How can you tell the Earth orbits the sun?

You can tell by the seasons, if the sun revolved around the earth the temperature would remain constant all year.


How much of the sun heat will be reduced if all the water on earth on the sun?

If all the water on Earth was suddenly transported to the Sun, the impact on the Sun's temperature would be negligible. The Sun's immense size and heat make the water from Earth a minuscule addition in comparison. The Sun's temperature and energy output would not be noticeably affected.


What would happen if the Sun's temperature were much cooler and it was much smaller?

If the Sun's temperature were much colder and it were much smaller Earth would no longer support human life


Which star's surface temperature is closest to the temperature at the boundary between earth's mantle and core?

The star with a surface temperature closest to the boundary between Earth's mantle and core would be the Sun, with a surface temperature of about 5,500 degrees Celsius. The temperature at the boundary between Earth's mantle and core is estimated to be around 3,000-4,000 degrees Celsius.


What would happen to the earth's temperature if a layer of the atmosphere dissolved?

the eath would seriously heat up because of the sun. the atmospheres act like sunscreen. when one of them is taken out, the earth would have a huge spike in heat.


What if the sun moved closer to the earth?

The average temperature would go up and the year would get shorter.
