If the sun burned out all life on Earth would cease to exist. There would be no heat.
If the sun heated the Earth evenly, there would likely be a significant impact on the water cycle. Different regions of the Earth receive different amounts of sunlight, which drives weather patterns and influences the distribution of precipitation. If the Earth were heated evenly, these patterns would be disrupted, potentially leading to changes in evaporation rates, cloud formation, and rainfall patterns globally.
This causes our weather.
If the sun heated the atmosphere evenly, it would disrupt the temperature differences that drive weather patterns in the Earth's atmosphere. This would likely lead to a breakdown of the water cycle, as it relies on these temperature differences to create processes like evaporation, condensation, and precipitation. Overall, the water cycle would be greatly affected and could potentially cease to function properly.
Without sun earth will freeze and it will be impossible to live on earth. Earth will be so cold.
If Earth were heated evenly, the overall temperature would rise uniformly across the planet. This could disrupt weather patterns, affect ecosystems, and lead to widespread climate change. It could also cause polar ice caps to melt, leading to rising sea levels.
it is heated by conduction by the earths atmosphere
Earth is heated by the sun, which is a star.
As the Earth does not rotate evenly, but rather at a tilt, the seasons would be skewed.
Radiation
No.
As the earth is heated by the sun, bubbles of air rise upward from the warm surface.
The ground is heated by the sun's rays penetrating the Earth's atmosphere and warming the surface. The heat is absorbed by the ground and retained, which contributes to the overall temperature of the Earth's surface.
