Why doesn't all the energy absorbed by the earth radiate back into space at night?

Not all the energy absorbed by the Earth radiates back into space at night due to several processes that retain heat. The Earth’s surface and atmosphere store energy absorbed from sunlight during the day, gradually releasing it over time. Additionally, greenhouse gases trap some of this heat, preventing it from escaping immediately. This results in a more gradual cooling process, allowing the Earth to retain warmth even after the sun sets.
