Surface temperatures can exceed 100\u00b0C, much like the Moon, which has no atmosphere. Without an atmosphere to trap heat (no greenhouse effect) or distribute it via wind, temperatures would plummet rapidly after sunset.\u00a0<strong>Places in shadow or during nighttime would become extremely cold.<\/strong><\/li>\n\n\n\n<li>The atmosphere helps regulate the Earth\u2019s temperature by absorbing heat from the Sun during the day and slowing its escape at night. This heat-trapping ability is what keeps the planet\u2019s average surface temperature around 15\u00b0C (59\u00b0F), making it suitable for life. Without this natural insulation, Earth would experience harsh temperature fluctuations between day and night, similar to what occurs on planets and moons with thin or no atmospheres.<\/li>\n\n\n\n<li><strong>Certain gases in the Earth\u2019s atmosphere<\/strong>, particularly greenhouse gases like\u00a0<strong>carbon dioxide (CO\u2082),<\/strong>\u00a0methane, and water vapor, have the\u00a0<strong>unique ability to absorb and trap radiation.<\/strong>\u00a0This property makes them especially effective in trapping heat within the atmosphere, contributing significantly to the greenhouse effect.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>I.
